Sam's carries the Yerf-Dog 3206. Which isn't as good as the Dazon/KPX/Twister models. It lacks reverse, front disc brakes, and ATV style hubs and wheels. I just ordered 2 KPX Xterro's from Toy Junkie's for $1999 each. I also ordered their performance kit(pipe, jet kit, and K&N) for an extra $300.
Where do get the performance CDI's for these Karts?

they say that they have an updated piston design and are sending it to me,
if it goes again I will use the lemon law...
The cart is basically a good design and well built, The motor is a copy of a Honda, down to the color code of the wiring.
The piston problem must be something new. Since they use that same motor in several different applications. My Yerf-Dog 3206 has the same motor and it's been trouble free for over a year now.

He mic-ed the pistons and found that there is no camber in the skirt. The skirt should be .007 to.010 narrower than the dome, he showed me this with a Wiesco, What he figures is happening is the side thrust is causing a problem.
When I explained this to the seller he said that the importer had just received a new/different batch of pistons from the factory.
Might have just been a bad batch.
Have you looked into aftermarket pistons? I know Ross will build custom pistons for reasonable cash outlay.

That sounds pretty interesting. Does Wiseco currently make a piston for these engines? If so, in what compression ratio's?

Is the suspension decent? the rear suspension has the engine on it, can it climb moderate hills such as getting out of a creek bed? Will we take a beating riding down average trails? My brother has a Rhino and that thing can literally go anywhere, I would like to be able to follow him at least some of the time, I know ground clearance may be an issue but I am mainly wondering if it has enough power to climb hills. thank you, Kell
Here's my experiences with these type of karts. I've owned three so far. A Yerf-Dog 3203, a 3206, and now a KPX Xterro(soon to be two - as I have a second one on order). If you're looking for a cheaper version of a Rhino, you'll be disappointed. The power to weight is just not there. And I'm sure the suspension is not as good either(I havn't been in a Rhino yet, so I'm speculating).
What these karts are is a cheap and fun alternative to an ATV. They'll climb some pretty steep hills, provided that they aren't too long and drawn out. A 45-60 degree hill is no problem as long as it isn't more than about 20 feet in length and you have decent traction. Suspension performance depends on the terrain and speed(and also which kart you buy). In my Xterro, 20 MPH on a rough road is no problem. 20 MPH through a set of whoops is. In my Yerf-Dog, you take a beating(from the wimpy suspension and hard plastic seats) pretty much all the time. So kart selection makes a big difference. From what you described as what you want, I think you'd be happy with one of "CLONE" karts. The clone karts being the KPX Xterro, the Dazon Raider, the Kasea AB150RII, the Twister Hammerhead, and the Carter Talon. Which are all the same kart with only some minor differences in appearance and performance. As long as your brother isn't purposely trying to ditch you, you shouldn't have any problem keeping up with him in one of these karts.
I almost like these things more than my 727 Raptor. Everything is a challenge!

Now if there was just a way to bolt on your R6 engine! I was curious, you must have the single seater, I would guess the double would be heavier. I had looked at the yerf dog at sams which was only about $1600. I talked to someone who bought one of these and said they did great but he was looking for bigger tires in the front to get more ground clearance.
My KPX is a two-seater. Click on the little camera to the left of this topic to see a pic in my pictures section. Or go to KPX's website for more info. Here:
http://www.kpxmotors.com/sandrail.html
The two-seater buggies are not much heavier than the single seaters. Only about 40lbs in the KPX's case. The Yerf-Dog you saw at Sam's was probably the model 3206. Which I also own. It uses the same engine/drivetrain as the KPX but without the VERY handy reverse. For an extra $500 over the Yerf, you can buy a KPX which is a much better kart IMO. The big problem with the Yerf isn't the small front tires, it's the wheelbase. It's a long kart that has a large turning radius because of it. Which makes the lack of reverse very annoying.
It's funny you should mention the R6 conversion. Because I've been doing alot of measuring and drawing lately. Not for an R6, but for my 727 Raptor engine. The reasons for the 727 over the R6 is that I think these little buggies really need reverse. Which the Raptor motor has. Getting unbuckled and out of the kart to push it backwards really sucks. And also, I don't think the kart chassis would take the 100+ HP that the R6 produces. And of course the Raptor would most likely get either a V-Max engine(with a chain drive conversion and a 1500cc long rod kit) or a Hayabusa engine for it's new motivation.

I recieved my second KPX Xterro(a blue one) today. The kit that Toy Junkie's sell's for the KPX is not a White Bros. I'm not sure who makes it. But it appears to be of high quality. And has a nice sound. It's deep and throaty, without being obnoxiously loud.

Also, I could not find the Toy Junkie place where someone ordered there's, I did a search and came up with nothing.

I put their kit on my second KPX today. It does make a little difference. It's noticeable but not drastic. The sound is great though.

Has anyone had problems with their chain Breaking? went to the dazon forum on some sandrail site and they where dogging the twister and kpx's because they only have one chain and they say they break alot. Not sure how this would happen, maybe if you jumped it with too loose or too tight of a chain?
The 2003 Dazon Raiders are the only ones I've heard of breaking chain's(in fact my buddy broke his). That's why the Dazon's went with a dual chain setup. Which is totally ridiculous. The best cure would have been to use a better quality chain instead of duals. That's what my buddy did. And he hasn't had any problems since. A 180 HP Suzuki GSXR1300 Hayabusa has the same size chain, and you don't see them breaking. Dazon must've been using the cheapest chain they could find. I havn't had any problems with my Yerf or KPX's breaking chains.

I checked the plug and it looks like the mixture is fine so I would hate to try and just lean it out. Anyone else check speed?
Thanks
I've checked both my Yerf-Dog 3206 and my KPX Xterro with a GPS. Both clocked in at 31 MPH.

Since these karts don't have a wet clutch, any automotive type oil will do fine. I'm running Royal Purple 15W-40 synthetic in the engine. And Royal Purple gear oil in the gear case.

I assembled it and fired up the engine...all seemed fine. It was 10:00 at night and my kids were flying around the yard and driveway for about an hour. We put it in the garage for the night and noticed a large amount of oil dripping out of the plastic housing that protects the clutch/flywheel/fan and the rest of the motor was drenched in oil as well. I disassembled the housing and the leak appears to be coming from behind the clutch pack (passenger side of engine). I assume the eqivalent to a cars rear main seal is the culprit but I'm not sure. Has anyone had this problem?
I attempted to remove the clutch pack but couldn't budge the nut, I think it was an 18mm. The cover behind the clutch is mounted with a series of 9mm bolts but I think I need to remove the clutch first. THis is the cover where the inductive pick up mounts to the engine in order to read the flywheel. Any suggestions are appreciated?
P.S. I did notice that the crankcase was over filled with oil from the factory but I doubt this is a contributing cause.
It is possible that the overfilling of oil caused excessive crankcase pressure to build up creating your leak. I'd try correcting the oil level first. If that doesn't work. Then here is a link to the online Yerf-Dog(same engine) service manual. You most likely will have to have a YAHOO account to access the link though.

Go here:

And then join that group. Once you are a member of that group, then you can access the manual. It's in the "FILES" section. It's actually a good group to belong to. It's mostly Yerf-Dog owners, but there are other kart owners in there as well.

For those interested, I finally took both of my Xterro's out for a comparison today. My blue one has stock internals with a pipe, jetting, and a K&N. And my black one has the same bolt-ons, but it has a ported and polished Yerf-Dog head with larger intake and exhaust valves.
No comparison, the black one spanks the blue one in a drag. And it's hill climbing ability is FAR greater. Hills that stop the blue one in its tracks, the black one trucks right up.

Kell
I'm not sure getting the Yerf head is necessary. The heads look identical other than the valves and combustion chambers. For my next conversion, I'm gonna see if my local motorcycle machine shop can put the larger Yerf valves in my KPX head. I only used the whole Yerf head because I had it available. And it was free. I'll be doing this conversion in the next week or so.

I put the pipe on this weekend and didn't have time to put the rest on because I was anxious to try it out anyway. I noticed an immediate improvement in low end power. It definetly had more grunt, not much added on top though. All of the screws on the back of the pipe were loose and I lost one. The pipe looks professional, the part that replaces the stock air system is pretty crude looking but I am into performance not looks.
Saturday I put the jet kit and filter on. The jet was a 145 and replaced a 108. Now the buggy seems a little slower again, also smokes now and the plug is black. Is there anyway I put too much oil on the filter? I squeezed the excess out with paper towels. 145 seems like a big jump to me. Can I find these jets locally? thinking of trying a 140 or 135.
Took the buggy out a couple of weekends ago to Turkey Bay which is an excellent off road park, maybe a little rough though. The buggy did good, had some trouble climbing steep hills. I did manage to bend the bar thing that sticks out of the strut/kingpin? that attaches to the end of the rack & pinion steering. Came off a pretty large jump and landed on one front wheel. Pretty harsh landing! All in all the buggy did very well, almost impossible to tip over (so far).
A few more things, the stock air filter is worthless, you can see the dust getting by this into the air system. My oil was filled too high also causing some to come out of that tube the other guy was talking about.
The last thing, I went ahead and bought castrol syntec 10/40, do you guys think this will work well in this?
thanks for the advice,
Kell
You should be fine with your oil choice. Your black smoke problem is definately a rich condition. The jump to 145 main is HUGE. Even a 120 in mine was too rich. Here's the carb setting's I found work best in these motors:
Shim the needle approximately .030"
Drill out the stock main jet .003"
And adjust the pilot screw to wherever it idles best(wait approximately 2 minutes before adjusting. It appears that the electric choke comes on everytime you cycle the key. Whether the engine is warm or not).
Those setting's should be close. Assuming you're somewhere near sea level. I'm at 1100 feet.

Not sure where to find the shim material, I don't have access to pilot drillbits either. Do you think I can pick up a jet that fits from our local bike shop? the carb says made in japan on it. When I ordered the pipe kit, they asked me my elevation which I didn't know at the time. I don't want to wait another week for them to get me another main jet. I guess a set of drillbits would come in handy though!
thanks for the input.
Kell
Oh yeah, had every kid in the neighborhood riding in the cart this weekend, and when I unloaded down at turkey bay there was a crowd around the twister but no-one around my bro's rhino. go figure?
I just use small machine screw washers for shims.
The main jets look like the same jets that my Raptor uses. Although I havn't compared them directly.
I'm not surprised that your Twister received more attention than the Rhino. These Karts are cool-looking compared to the Golf-kart appearing Rhino. Too bad these Karts don't have the Rhino's power.

SMOKES LIKE CRAZY when I start it. After it runs a little bit it stops though.
If it only smokes at start up, then the valve seals are most likely the culprit.

Hopefully only the bigger Yerf valves are needed. The KPX has a smaller combustion chamber and subsequently more compression. So I'm hoping to be able to put the larger valves in the smaller combustion chambered head. After Halloween, I find out if it's possible. If not, then I'll be putting on a whole Yerf head, and decking the cylinder and head to get the compression back.

thanks
The 4x133 pattern is the same as the Kawasaki Bayou. Which limits your wheel selection. I've found that the easiest way to convert to a more common pattern is bolting on a set of Raptor/Banshee/YFZ hubs. Which have the same splines. Making the pattern a 4x115. They can be found on ebay for $15-25 a pair.

Just some FYI. You all should go check the planetary drive(the reverse mechanism) on your karts. Both of mine and my buddie's Dazon's were bent and on the verge of failure. It's an easy thing to overlook until it breaks. I built some custom brackets last night for both of mine. We'll see how they hold up with paddle tires at Glamis this weekend.

How does he like that Dazon? I keep hearing that they are faster, but I don't see how that is, since it's the same engine and all... right?
-Steve
The engine's in these karts are all VERY similar but they are not exactly the same. They use different CVT/gearcase ratio's and piston/head combinations. The Dazon appears to have the best of all those parts. Lower CVT ratio for better off the line sprints, and bigger valves for better top end breathing. So they are faster from the factory. Even my ported and polished big-valved KPX is unable to beat my buddie's piped-only Dazon. He'll get the holeshot, and then we stay even(me about 2 karts back) until they both top out.

The "C" shaped bracket mounted to the planetary case twists.
I've fabbed up a dual bracket setup to better distribute the load. If it makes it through this weekend, I'll post pics.

Wow.. okay, good to know. And he is in the double seat Dazon, too?? If that's the case... imagine how much faster off the line the single would be.
Now... is the price worth it? Big price difference there.
Have any experience with the Carter Brothers Talon line??? Wondering how they top out... all three of these are apparantly built by the same factory.
Some sites seem to claim 13 hp on the carters... but I see 11hp claims as well. Get's confusing here.
-Steve
He has the single seat Dazon. So we ballasted it(him-205lbs versus my wife-125lbs) to make up for the difference in weight.
If the price difference between the Dazon and whatever other kart(KPX, Twister, Carter) your looking at is only a couple of hundred bucks, then I'd pony out the extra cash for the Dazon. It appears Dazon goes the extra effort to build the better kart. In my case, the KPX's I bought were $700 a piece cheaper. So I can do the motor/gearing upgrades cheaper than it would've cost me to go with the Dazon's.
Plus the Dazon's have a bench seat, and I liked the KPX's buckets better.

I think I will keep the stock tires but want aluminum rims. Anyway, I think the stock rims are 9" wide, will it hurt to go to an 8" wide rim with these tires. The tires "say" 22x10x10, and I believe the offset of the rims are 4&5 with the 5 on the inside of the wheel (can't remember if they call this negative offset or not). Anybody have any advice? I am trying to reduce the rotational weight, ideally I would like lighter tires but I DON'T want wider tires. It's already hard enough to spin them. If I go to a narrower tire, they all seem to be 18's and that would really reduce ground clearance. The 10" steel rims seem really heavy to me.
8 inch wide wheels will work fine. That's what I've been running on the back of mine. They have a 3 inch offset(to the inside). Also, the stock steel wheels aren't as heavy as you may think. I've weighed them against a set of Douglas .125 aluminum wheels, and they are only 2.5lbs heavier. So a .190 aluminum wheel(which is what these karts need) is probably not any lighter than the stock steels.
Posted by: RAPTORAZ
For those interested, I believe I've found the reason for the Dazon's higher power output. I've acquired a Dazon cylinder head, and it appears to be a MUCH superior design over the KPX or Yerf-Dog head designs. It has the larger valves(like the Yerf), but it has a better combustion chamber(semi-hemispherical versus the KPX's and Yerf's heart-shaped chamber. Which really unshrouds the valves promoting better flow). I'm in the process of porting the Dazon head, and I'll be installing it on my Blue KPX this Saturday. Look for a review(I'll drag race them out front!) of my ported Dazon headed KPX versus my ported Yerf headed KPX soon after.BR>
Also, my custom planetary brackets held up great at Glamis last weekend! All they are is 2 pieces of 1 inch wide X 1/4 inch thick strap ran to the engine from the planetary drive.

I'm doing the porting myself. Along with the guidance of some of my "Race Car" buddies. The porting is not much. Mostly just cleanup with a little material pulled off of the roof to help straighten the air path. I'm also port matching the intake port to the intake manifold and spacer. Or visa versa. Depending on which is greater.

I forgot to mention that I also reshape the ledges around the guides. That is where most of the material is being removed.

Dazon head swap update.
The swap is a bust. The Dazon head is approximately 1/2 an inch taller than the Yerf and KPX's cylinder heads. Which means the cam chain and head studs are 1/2 an inch too short.
So for now, I'm porting my Blue KPX's small valve head. Look for a comparison between my ported KPX small-valved head against my ported big-valved head after this weekend.
Side note:
I believe the Dazon head is still doable. But it's gonna require splitting the cases to put in a longer cam chain.

If I'm not mistaken, the Subaru-Robin motor is just another lawn-mower type engine with little performance potential. You'd probably be happier going the KPX route.
Posted by: RAPTORAZ
KPX engine update:
I just got done with the modifications to my blue KPX today. I ported and polished the intake manifold, the spacer, and the intake and exhaust ports. I also milled the head .050" and used a .010" thinner cylinder base gasket. The compression ratio went from a before as measured 9.1:1 to a measured 10.6:1. The cranking compression went from 150 psi to 180 psi.
Performance wise, it has a TON more off idle torque and hits the rev limiter pretty easy.
Look for my full report after next weekend from Glamis. I'll be putting it up head to head against my ported and polished big-valve Yerf-Dog headed black KPX.

I've been searching the net for one. But have yet to find one. I tried the White Brother's box off of my 416EX, which physically plugged in, but it didn't work. The kart missed and sputtered with it. Anyone know where to get one of these "REV" boxes?

It's definately a KPX. The model number on the spec sheet gives it away. The pipe and filter kit on that one is the same as what I am running. And they are very near a drag pipe. VERY loud. I'm planning on building my own here soon. As I think they are now costing me some power on my modified motors.

Don't quote me on this, but I've heard that only the Dazon's are eligible for a green sticker in California. As for my KPX's, they came with titles, registrations, and off-highway vehicle plates. Making them legal for use on Arizona land.

I was gonna make a whole review of my Glamis findings. But it isn't necessary. Even with nearly 2 full points of LESS compression, my ported big-valved Yerf-Dog headed Xterro smokes my ported small-valved KPX headed Exterro. Looks like I'll be ordering another Yerf head and valves for my blue KPX Xterro soon.

From the sounds of it, it was a direct swap... but I'm curious too if there were any kinks along the way or not.
Does Yerf sell the head directly or do you have to go through a dealer???
-Steve
You can buy Yerf parts directly from Yerf-Dog.
As for the swap, when I did it, I had the whole Yerf motor. So I swapped over the entire upper end(cam, head, jug, and piston). The swap was a direct bolt on. I measured everything at the time, and it all seemed the same, other than the Yerf's larger valves and combustion chamber.
This next swap will be a head and valve swap only(it'll get milled this time though, for more compression). So I'll let you all know. It should be done within the next week or so.
Also, the Dazon head was a bust because the KPX's cam chain being too short, not the bolts.

If anything the freer breathing larger valves would help to unrestrict the motor, making it run cooler.

In any event, my Yerf valved KPX has .100" bigger valves than stock, and I havn't had any overheating issues.

bladepowersports.com do you think they might be pretty good. they say the do 45-50 mph, but, i dont know about that. give me you feedback.
thanks

Judging from the pics, I'd say they are a Dazon clone. The bodywork looks real close, and they have the same idiotic dual drive chain setup.

They also have what looks like an identical cvt. I have ridden a couple and was not too impressed with stock form but having much more experience with 2-strokes than 4, I know the potential for probably more power is there. If you haven't ridden a modern cr80 lately, you would be suprised at the power they can put out. They run like a good 125 used to and a 50cc now runs like an 80.
I think the weight of the kart with two people would overwealm any 90cc engine, stock or built. The problem with 2 stroke engines is that they have no torque. And that's what these karts need. I've thought about a 2 stroke conversion myself. But with a 250 Trailblazer motor(air-cooled with a forward and reverse CVT). The whole ATV can be bought used for around $1500. You could probably part out the rest of the quad and make nearly all your money back.

New main jet is a 120.
Didn't shim the main needle yet... What exactly does this achieve?? I assume it might richen the mid to top end a bit more too?

Does it pop coming off of a WOT run or just normal cruising?

It's not too serious... but it's definately there. I made sure I checked all fittings really well after install, so I know everything is tight. I'm really close to sea level here (an ocean front town) Might very well need to be a tad richer. But, from what i've heard, 120 is about right or even a little rich for some people.
So, if it turns out what I have is mid-range popping, and not truely WOT popping... what am I looking to change? Shim the main needle a bit at that point?
-S
Sounds like it's a little lean at the top. Instead of putting in a bigger main though, I'd shim the needle about .020". You'll richen the top a little, and it should also pick up the midrange response.

Anyway, I recently started leaning toward the KPX. I found this post via a search. I saw the pictures of yours. A few questions, if you don't mind:
1. You've obviously contributed many posts to this board, so I'm assuming you've done your homework prior to the double purchase of the KPX. Can you please tell me what swayed you to this machine? I had originally decided on the Twister, but have seen countless reliability issues.
2. I keep seeing that many of these buggys are basically the same thing, just minor changes depending on the make. So why do some say 35mph and some 40? I keep seeing that the motors are similar to Honda. Who really makes these 150cc motors?
3. You mentioned you bought your karts from Toy Junkies for 1,999. I have not found this price or the Toy Junkie site. From what I've seen, this is the lowest price on this type of unit anywhere.
4. How long did it take for you to get your karts once paid for?
5. Please tell me about the performance kit you also ordered. How much does it really help performance, low end and top end? And, how does it effect the noise level?
6. I keep reading about receiving the Karts crated, where assembly is required. I'm very handy, but I even read to "have a professional assemble ... comes with no instructions." Is this a big deal?
7. I thought the KPX colors were red and blue, but it looked like your wife's was black???
Thank you in advance!
Joe
Answers in order:
1) What swayed me towards the KPX's over the others was price and equipment. At the time, the $2K I paid was $300 cheaper than the Twister, and $700 cheaper than the Dazon. I also liked the twin bucket seats(vs the Twister's bench) and the larger rear rack(versus the Dazon's smaller one).
2) The claimed speed is all marketing hype. My Yerf-Dog, my KPX's, and my buddy's Dazon all ran within 1 MPH of each other according to my GPS. As I understand it, the motors are a copy of an old Yamaha scooter engine. They are manufactured by a couple of different companies and they all have minor differences. So far, all the ones I've had apart(Yerf-Dog, KPX, Dazon) have had the same shortblock, but different cylinder heads.
3) Toy Junkies no longer sells the KPX's for $1999. They are now $2399. I've been watching some Ebay auctions for a couple of weeks now. And the 2005 models have been going between $1800 and $2100. So that is probably your best bet if you decide to go with a KPX.
4) Since both Toy Junkies and I are in Arizona, I received my first one(the black one) the same day. But I had to order the blue one. Which took two weeks.
5) The performance kit was a noticeable inprovement in power across the board. However it's LOUD!
6) My KPX's were bought assembled, but I did have to assemble my Yerf when I got it. It was simple. Anyone even remotely handy could do it.
7) KPX only lists them available in blue or red, but they are also available in black. Which when clean, and in bright sunlight, looks awesome. All the metal flake in the paint makes it almost have a color shift effect. Unfortunately, when dirty, it looks like poop. The blue one does a better job of hiding the dirt, but it shows the scratches much more than the black one. So it's all a matter of opinion. The red one I'm undecided about. It's kinda a red/pink/maroon/purplish color. All the colors look dramatically different in person than in pics. So don't judge the colors by their pics.
Sorry for the rambling. Let me know if you've got any more questions.

Does the pipe stick straight out(a perfect 90 degree angle) from the head. Like the KPX. Or does it bolt to the head at a slightly different angle? Angling the pipe towards the rear of the kart.
Posted by: RAPTORAZ
For all those interested, I've been watching some Ebay auctions for a while now. And here's what I've seen some auctions close for:
1 seater Pirate 150(appears to be a KPX clone) = $1600-$1700
2 seater Explorer 150(also appears to be a KPX clone) = $1900-$2100
1 seater Blade 150(appears to be Dazon clone) = $2000-$2100
2 seat Blade 150(again appears to be a Dazon clone) = $2200-$2400
After comparing the specs between the Explorer's versus the Blade's, I think the Blade's area better value. For the extra $200-300 more, you get better seats, nicer wheels, bigger front tires, a speedometer, a hitch, and better lights.
Just some FYI for those looking to buy a buggy.

The crank case on the XTV has some added mounting points on the bottom that will be really obvious in the pics. The head looks the same judging by external reference points. The plastic case surrounding the head on the XTV is identical to the Xterro.
No way to know the really important stuff though without removing the head of the XTV.
Judging from your pics, I'd bet that the XTV has a similar head design as the Yerf. Since the Dazon's exhaust port angles back.

It sure would be a benefit for all us non-XTV owners to find out if the XTV truly has a larger carburator.Any XTV owners out there wanna measure the inlet and outlet diameters of their carb's?

I've emailed KPX with both of those questions and received no response.

My blue KPX(for some odd reason, my black one has been bulletproof), and my buddies Dazon have both had many electrical glitches. Mostly caused by bad connections. If the selling dealer won't cover labor while it's under warranty. Then you might as well just get one off the internet.

hopsterguy, thank's for all the info and the comparison of the two karts.
I called Carter as well today. The XTV's carburator is $90 and the intake is $15. Sounds like this is gonna be the next mod for my KPX's.BR>
Could I get you two measure the bolt spacing(on the intake manifolds) between your karts? Maybe even do a clearance visual between the two as well.

Sure, just have to give me some time. I want to look at how that throttle cable is mounted on the ATV style carb on the XTV as well. Never seen the inside of one of these types of connections. Maybe you have.
No problem. Typically the throttle cable cable is connected directly to the slide on that style of carb. So as you pull on the cable, the slide goes up. When you pull off the top cap, the slide will come out with the cable end. Be careful, sometimes they "pop" out with some pieces coming off.

Nice pics. So much for the XTV carb transplant idea. I'll call KPX today, and see if I can get any more info on the bigger carburator rumor.

Just got an idea. Did you try the XTV carb/intake with or without the plastic spacer in place? The intake/carb might fit if you remove the 1/4" spacer off the head.

Looking at those pics gives me another idea. How about using longer studs and a thicker spacer to get the XTV's carb above the Xterro's frame rail?

Typically, during an outing, what should I be prepared for? Some great links would be nice??
Best terrain: hard pack dirt, woods, low elevations
Spare parts: volt/ohm meter, wiring schematic, and electrical connectors
Flats: havn't had any yet, but tires are easily blown off the bead if the pressure is too low
Chain: still using the originals on mine
Outing preparation: prepare to have stupid amounts of fun. My buggy's see far more use than my ATV's

RAPTORAZ, any update on this.
I would like to know specifically if I can get away with just ordering the head and valves, I am not sure if your other xterro had the whole yerf dog jug and piston or not. Do they sell the gaskets in a kit or do I just need to order one head gasket, I think the valve cover is an O-ring? Any suggestions about milling the head a little to boost compression? Also, you mentioned after porting the stock head that it hit the rev limiter, would it be a benefit to order the cdi mentioned before to raise the limit? I have never hit the rev limiter on my twister, that I am aware (even down hill).
thanks,
Kell
forgot: Also, I think you mentioned you were running aftermarket wheels that made offset wider than stock, any problems bending the axle etc. so far? Seems like the people running the stock balloon type tires could benefit from flipping the rims to widen the rear end (I have rolled mine, even with my squared off tires) but could stress the axle more. I can't get away with this because it just barely fits backed up into my truck as it is.
I don't have any updates as of yet. Been having overheating issues with my 727 Raptor that has been eating up my time lately. My black Xterro does indeed have the entire Yerf upper end. Piston, jug, head, cam, valves, etc... I swapped everything, because I had all the parts. I'm 99% sure that all the would be needed for the swap is the head and valves. The gaskets do not come in a kit. They are all individual. I've used gaskets from both Yerf and Dazon, and havn't noticed any difference between them. All you'll really need is a head gasket. I've reused all the others without any problems so far. As far as milling goes, since the piston's do NOT go to zero deck, you can remove a lot of material without worry. I removed .050" off the head, and used a .010" thinner base gasket on my blue Xterro. The chain tensioner has no problem taking up the extra slack. And the piston to valve clearance isn't even an issue. I was wrong about the rev limiter. It was a loose connection that caused a high RPM miss-fire.
I'm actually running the stock wheels reversed. Which widens the kart by 2 inches in the rear. I have noticed a wobble(when operating the kart off the ground) in the rear axle. Since it can't be felt while driving, I havn't looked into it.

Mirrors are in a different place, the console that was on the old pictures is not there... the placement of the headlights is higher and now only two lights instead of 4. I hope those people that bid on the first 3 auctions actually get what they bid on. I wouldn't be a happy camper, myself.
Original ebay listing
New listings
I prefer the looks of the older(1st listing) karts as well. But the new ones(2nd listing) do show some improvements. Such as, better rear tires(flatter profile=less tippy), seat lever placement, better steering wheel(looks better, could also be less flexy), and a different reverse bracket(possibly stronger?).

Prepare, this is going to spawn into several questions. The spare part was a tube. The tube is about 10 inches long and looks to be a breather or a gas line.
So I looked over the machine closely for some place a tube could connect but didn't. I found none. Then I thought, maybe it connects to another tube. I found four tubes which were connected on one end only. I will provide manual pages and part numbers for those who have the manual.
Tube 1art Ref No.10, Part ID#M150-1001001. This tube comes off the cylinder head cover. One end is connected to the port off the head and the other end is thicker and has a clamp connected on it but is not connected to anything. Sometimes, these things are fed back with a PVC valve to the carb so I think this is a high candidate for connecting to something "it has an unused clamp so it must go to something!"
Tube 2art Ref No.22, Part ID#M150-1003400. This tube comes off the crankcase and doesn't terminate.
Tube 3art Ref No.28, Part ID#16199-GT8-600. This tube comes off of the float chamber and is used to drain fuel for winter storage so probably only one end should be connected.
Tube 4art Ref No.19, Part ID#95005-45270-50. Very short tube bending down coming off of the carb. Probably the intake for the needle jet?
Any info on the mystery tubes and these 4 tubes would be appreciated. The Kart runs as is but idle isn't perfectly steady. However, my 245lb bulk climbed 500 feet of nearly vertical mountain with the gas pedal barely down so the low end torque is awesome on the 2005!
Thanks
Heath
I'll look in my book for you. Some pics of the part in question would be helpful though. Do you have any pics of your kart yet? I'd like to see what the 2005's look like.

Another question about the Kart itself ... They call these transmissions AUTOMATIC, but do they really just have one speed/gear, or do they actually shift automatically??
I'd go with the red one for two reasons:
1) It'll look better than the black one when it's dirty.
2) The red is more visible. Which means you'll be less likely to get run into by other off-roaders(I've seen it happen).
These karts have a constant-velocity transmission. Which means they have two pullies that change diameters to give them multiple gears.

I took the petcock off and was able to blow into it, but not out of it. Maybe that's normal and just needs to have the compression to suck gas through. I'm not sure. Anyway, how can I get the fuel flowing?? And, should that additional line from the tank be going somewhere??
I have to go to the inlaws this afternoon, so try to respond quick. Thanks!!

The fuel valve is vacuum operated. So it only flows fuel while the engine is running. The hose goes to the fitting on the the left hand side of the intake manifold.

I see gas flowing now. It started, but quickly died. I cranked it a few more times and it started almost a couple, then the battery died. After another close look, I found another vacuum hose not connected. I hooked it up and had enough battery to start one more time. It ran for about 5 seconds, but quit the second I gave it any gas. Maybe it needs some tweaking, but I certainly don't know what. I really don't know what to try. Also, what do I need to know when charging one of these little batteries. I have a typical Craftsmen charger.
I also noticed another rubber line/hose near the back of the motor coming from the top of what seems to be the drives housing. I have no idea what it's for, but it's not connected to anything. If it's another vacuum, I see no place for it to go.
Sure would like to ride this thing.
Joe
It's a 12 volt system. Just like a car. Charge it at a lower amperage level is possible though. After it fires, just let it idle for a minute or two. The electric choke will come off after about two minutes. Then it should run fine.

The one time I tried the gas, it reved some and quit anyway.
I'm sure I shouldn't mess with the carb adjustments, but my unprofessional opinion is that the idle seems to low. I think it may be fine if it can ever stay started and get warmed up. But if each cold start is this way, it's going to need some type of adjustment.
My wife's bro will be in town tomorrow. He is a jet engine mechanic and former motorcycle mechanic. He still rebuilds wrecked bikes as a hobby. He'll take a look I'm sure. For now, any more ideas??
Joe
Crank up the idle. You can always turn it down after it warms up. Hard starting shouldn't be an issue. Both of mine start right up.

I'm still wondering about maybe another vacuum hose issue. By the way, did the hose at the top of the back engine casing ring a bell? It's a typical black hose, similar to the fuel line.
My gals are driving me crazy. I don't blame them at all. I guess I'll try again Sunday.
Joe
The hose at the top and rear of the engine case is the differential gear case vent. You can either leave it open. Or put a very small filter on it. Mine are open since they vent outward pressure. Since it's cold outside, try adjusting the idle mixture screw out. It's on the left hand side of the carb, just forward and above the fuel bowl. I'd try 1/2 of a turn counterclockwise.

If you're looking for a more common pattern for the rear, Yamaha hubs bolt right up. I'm using Raptor hubs on mine, and a buddy of mine is using YFZ450 hubs on his. Banshee and Warrior hubs should be the same as well. Used ones can be had off of Ebay for under $25.

Throw away the locking lug nuts! They're not necessary. I've also had to replace some studs due to the junk nuts. I simply used grade 8 bolts that were the same length and tack welded them in. Been working fine.

These buggies are really starting to take off. I saw at least ten different ones this past weekend on my Glamis trip. Mostly Twister's from what I saw. I even saw a single seater with a fiberglass '32 Roadster body on it. Way cool!
My two did great this past weekend. I even launched my black one off a really good jump. Had to be at least 3-4 feet off the ground. Came down with a THUD, but didn't break anything. The only failure I can report, after a brutal flogging all weekend, was a dead battery.
How's everyone elses Kart's holding up?

I hate to try and order one from the local dealer it would probably take month and probably not be the right one.
your help would be greatly appreciated.

Ps. Anybody with a Hammerhead? Better check every nut and bolt on it. I am tired of everything falling off of this one.
Loose hardware is a normal part of off-road vehicles. My ATV's lose nuts and bolts all the time as well. I'd suggest making Loctite your best friend. As for your missing nut, just measure the shafts diameter.

We took our cart out for the first time after the breakin period on MLK day and had a similar problem. After hitting a bump in the road the chain went slack and the cart won't move. On closer inspection the output shaft from the gear box is sagging. It looks like something inside the gear box snapped.
Has anybody done any work to thier gear box yet or are these "black boxes". I have been trying to get ahold of KPX but thier tech support has been out sick.
You're the first I've heard of having any gear box problems. So I'd say it's an isolated problem.Let us know what KPX does for you. Hopefully a new Kart will be the outcome.

just gotta have a little extra hp!!!
The Yerf has a larger combustion chamber than the KPX. So unless you want to lose 20 psi of cranking compression(which is probably 1 point of dynamic compression), you might want to shave some material off the head. On my ported KPX head, I shaved .050". And I also used a .010" thinner cylinder base gasket. That brought the measured compression ratio up from 9.1:1 to a measured 10.6:1. If you want similar results, you're probably gonna have to do near the same. Maybe even use an even thinner base gasket. I believe the stock gasket was .040" thick.

All I know is my particular kart was faster then those other particular karts I raced. We did flat out drags and I was quicker off the line and they never came close. We did it a few times to rule out reaction time.
Them we raced on berm tracks with the Twister. If I went out first I would pull away. If he went out first I would ride his tail. We even swapped karts. His seat was nicer because mine was a 2004 and Dazon had not upgraded to the race seats but I think the new Dazon seats are way better then the Twister seats.
OCduner
You wouldn't happen to work for Dazon or a Dazon dealer would you?
I've done multiple drags as well with My KPX's, Yerf, and Dazon. In stock, bolt-on, and internally modified forms. And yes the Dazon is faster in all forms. But not dramatically so. Only a length or two at most. And that's only in a drag race. Top speeds are all within a mile an hour or two(GPS verified).

The ported Yerf head was a MUCH bigger improvement than when I just added the pipe and filter.

But the thing that got my attention most was the exhaust.

What aftermarket pipe are you using? My Toy Junkies pipe is the same diameter as the stock pipe.

If this is larger than yours it may explain the larger increase in power from the pipe versus the yerf head that I experienced.
Thank's. I'll make a trip down to Eastside and check it out.

I "clayed" my ported small valve head before I milled it. I put enough clay on the piston to make it even with the top of the cylinder, and turned the motor over by hand a few times. The valves left NO marks in the clay. At the time, the piston was approximately .090" from zero deck. So I figured that removing .050" was no problem. Since the piston had valve reliefs on top of the .040" of deck height left. I didn't clay it after the milling.
I went and looked at the Eastside pipe today(took my TJ pipe with me). The Eastside pipe was a MUCH better looking peice. And much larger in diameter as well. Looks like I'll be getting one of those as well soon.

Eastside told me that that don't even use an exhaust gasket. They bolt the pipe directly to the head.

If you mill the jug, you'll remove the lip that holds the sleeve in place. Without the lip, the sleeve would be free to travel downwards towards the crankshaft.

Looks like I'll be ordering another Yerf head and valves for my blue KPX Xterro soon.hr>
Update:
It would seem that the small grooves I had in my Blue KPX's cylinder(from a slightly mishapen factory piston) made a much more significant difference in power than I thought.
I got KPX to warranty a cylinder and piston for me. Here's my latest findings:
My Blue KPX has really come alive with a fresh bore. My two buggy's now run side-by-side with each other until top end. Where my Blue one now starts to slowly pull away. So it seems that the added compression was worth more than the larger valves. Especially at the bottom end. The Blue one struggles less in the soft sand than my Black one.
Time to up the compression on the Black one. And put a Yerf head on the Blue one. Best of both worlds!
Modifications list:
Blue one - Ported stock small-valved head
Milled head with thin base gasket(10.6:1 measured compression ratio)
Toy Junkies pipe and filter
Black one - Ported Yerf-Dog big-valved head
Yerf jug(8.2:1 compression ratio)
Toy Junkies pipe and filter

Top speed on these karts is simply a matter of gearing. It's a trade off. Higher top speed = slower acceleration.

It is a bit dissapointing and recently have been looking at a replacment engine preferrable an automatic. say about a 300cc. hoping an atv engine could fit without too many headaches. has anyone attempted anything like this?? if its impossible for an engine change how else can i get some more power out of a 150cc motor. other than the exhaust. i found 2 sites check these out
www.turbonator.com or
www.tornadoair.com
anyone used these parts? would they work on a twister? is this possible?
although i reckon the cart is well built, jumps well, and good fun but that extra 100cc would be perfect....
Go back and read this entire post. These little engine respond very well to pipes and internal modifications. Not only are the mods simple. But they are also cheap.

Adding reverse is definately doable. I've seen others do it on Yerf-Dogs. I'd do a search on Yahoo on the subject.

These Buggies are approximately 200lbs heavier than a Banshee. With the Banshee's lack of low end power and violent powerband, you'd be hard-pressed to keep the thing together. I'd suggest using a larger four stroke engine.

I'm gonna have some fun modding this thing...
All these karts use the same basic engines. Which are all scooter based. The transmission is actually part of the engine assembly, like most motorcycles. So an engine swap would also require the use of a different transmission. As for a carb swap, I put a 400EX carb on my 250cc Sand Devil and am very happy with the results.

Yes. I've had my 150's at both Glamis and Buttercup many times. Traction isn't a problem. It's power. They just don't have the stuff to go through the dunes. At Glamis, they'll cruise the flats and washes just fine. And they'll even go through some of the smaller dunes, but that's it. Mine do a little better paddles, but not enough to justify the cost. Especially since the buggy's weight, around 750lbs with two passengers(in your case), eats paddles rather quickly.

After I re-geared it, my Sand Devil does very well in the dunes. In fact, I've duned it all the way to China Wall. It does take some skillfull driving though.

I finished my wifes twister kart last month. I basically did a full chop and slash in the suspension/motor department. The radical swap of parts allows me to use our Polaris dealer for all spare parts. It'll gps 48mph on level asphalt. Test drove it at Dumont two days ago and it ran all over the the left dunes without paddles. I will get paddles before the next trip to Dumont in the fall. In the really soft stuff I would have liked more traction, plus my 24" rears were to tall for my gears/power in the sand.
I posted some pics.

Posted by: Slowride
pics are on my profile page. they explain what I did faster than I can type.
I did the swap strictly for more power. My only problems with the stock kart were the reverse cable and some bolts coming loose. I wanted more power and a better suspension.

Posted by: Slowride
The rear suspension is like floating on a cloud. Front is a little bouncy with the heavy duty front springs. I've got to change the front struts to something with more dampening. When I say bouncy, I'm referring to full throttle crossing deep whoops lasting for 3/4 mile. Regular terrain or trail riding, the front and rear work great.
Billet is an Air Fuel ratio gauge to make sure the jetting is real close. It also does a good job of reminding me when the air filter needs cleaned. We wheel anyfrom from sea level to 9,000ft, I like seeing my jetting.

The billet I bought was from a dune buggy shop. Just a plain ol' 2" gauge holder.

Thanks Kell.
The folks around here were not seeing my vision when I started, but it worked out pretty good. Once they drove the kart, they couldn't believe the radical change.
There are a few things I would have done different, but its a pretty good solution for the amount of power I have. On the polaris CVT, I went with a heavier spring to let the motor rev higher before it hits the belt. This gave the kart more snap out of the hole, kinda like a stall converter on a race car.

Posted by: Slowride
Kell,
My new front suspension is nothing but comprimise. Basically, unless I wanted to add 12-16 inches of length to the kart, I couldn't get the front geometry to work out, especially with were the rack and pinion is mounted. So I took the easy route.
The Polaris front struts were a real simple mod. I did them in one day with nothing more than a weldor and metal saw. Luckily I had some heavy duty front springs in the garage because the stock Trail Boss springs couldn't support the weight of the front of the kart.
How fast does your kart run with all the mods? If we didn't play in the sand so much, I would have left it stock.

hopsterguy - I would probably get a two seat buggy and that Titan II looks good with the GT package but they have no specs or info on their web page and hopsterguy said the peirspeed 250 was a dog lacked speed and suspension movement so is the Titan II similar in those ways? watching the videos it sure looks faster....
So who has the best deal on the Twister Karts they seem to be the one that everyone on here likes the best? Also I did read someplace that they will be coming out with a 250cc Kart later in 2005.

Does anyone know if the Titan II 250cc Kart is any good? I keep waiting for Twister to come out with their 250cc model but have not seen any mention of it in a while. Thanks

thanks for resonding...
what model did you ride?

4wheelhi,
The wheel base on the hammerhead was too wide too fit in the back of my truck(I do not have big truck) so I decided against buying one. I figured since I would be spending most of my time fishing and hunting Id get an ATV. and im glad I did because I rode a friend mines after I posted this and let me say that my riding lawn mower pulls out quicker than those things, they are also it was vary doggy up hills. I bet if you souped it up it would be awsome though...later
Posted by: dadsworry
By the way my other buddy has a Dazen (sp?) and is a smoker!! on a half a mile stretch it beat the hammerhead by like 15car lenghts! they also burn up hills alot quicker. but im sure with some mods yours would be a hek of alot better. Id be scared too ride a souped up dazen!!!!

details or link?
There are two major Chinese makers of karts, Yerf-Dog and Jiong-Chiang. I see Yerf-Dog all over, the others are a fairly recent explosion. They come underpowered, but a new pipe, CDI box, and hotter coil lets you retune the carb for nice output. I test drove a stock one, and a modded one that the dealer had done for himself. Unmodded felt like a lawnmower motor powered it, modded felt like the ATV motor it was suposed to be.
No report on longevity after mods, though. He had just done the mod. It's been about 4 months, and he still rips around on it, though.
Posted by: Cheapass
I rode the two seater Jiong-Chiang, burgandy in color. They have a metallic blue that's real nice.
I think a performance CDI is really all that they guy did to it, then richen up the fuel a tad. It moved really nice after that.
Posted by: Cheapass
Eww!
One thing to question: Who assembled it? they arrive crated, with a fair amount of assembly needed. I don;t know it they have inherent problems, or maybe your dealer assembles them poorly. Either could apply.
Posted by: Cheapass
Could be. Haven't dealt with the Hammerhead2. Did they change the oil? I noticed that my bike came with some thin watery oil, so I immediately changed it for some 30w50 without additives. (About the best for an air cooled wet clutch bike)
I would not have trusted that thin oil in any kind of heat.
Posted by: Cheapass
Look in to a new CDI and raising the carb jets a size or so.

I had looked at the yerf dog at sams which was only about $1600. I talked to someone who bought one of these and said they did great but he was looking for bigger tires in the front to get more ground clearance.
thanks again for the input,

Get creative, and measure the mounts from an Odyssee or Piot engine/tranny. Maybe you can beef that puppy up, and still keep the two seater setup.
I bet larger, softer wheels would improve traction, ride, and clearance, too. need more oomph to push them, but a two stroke 350 out of an odyssee would do that nicely.
Posted by: Cheapass
Yes on that oil. I have found, fairly universally, that Chinese/Tiawanese motor producs come with very thin oil. Something like 20 weight. BR>
i DRAIN THEM AND PUT IN 30w for break in, and 50W for running. In these, cheap oil, I think, is best. The cheap brands don't put in the additives that the expensive ones do, which is better for a wet clutch.
Posted by: Cheapass
Out of curiosity, jetted at 140, try a pod filter directly on the carb. If this restores the fuel balance, the new exhaust can be used to it's fullest and the power increase should be profound.
Most likely 140 is too much, though. You'd need a very free flowing pipe and pod to need that kind of jetting.

I just bought two Twister HammerHeads.. there pretty fun although, to slow on the take off for me... but once you get going they'll do at least 40mph. I rolled one upside down going around a corner to fast and got out rolled it back over and kept going. I lost a couple bolts one the clutch arm on BOTH buggies and went back to the place I bought them and they'd said the manufacture had made some mod's to fix that problem. All and All... I'm happy with them.. and they're selling like crazy around here so when I'm done I can always sell one of them.. the other will be good for hunting and putting around. It fits perfect in the bed of a truck.
Posted by: 4wheelhi
Are you talking about these Twisters? If so I'd like to hear more info if you have it.
Posted by: 4wheelhi
Well.. like ANY 4 wheeling vehicle you that you plan on abusing off road.. you have to maintain it. The twisters require changing the oil every 10hrs of abuse and you should check for loose bolts and CABLES before every ride. I don't think it's poorly designed, I think for what you pay for it and how its driven its a fairly well ride'n machine. Although, I'd agree with most, it could you more power on the take off and up hills, but on the flats I'm doing a good 40mph around turns fish tailing and tearing it up!
Posted by: 4wheelhi
WOW.. that sux. So did the warranty cover you? I had broken the clutch guard cover on BOTH units the same day and the dealer ordered new ones free of any charges.
I've pushed both mine pretty hard but only had them out about 5x this summer. Actually thinking of selling one and buying a quad runner. The other will make for good chores and hunting use.
I'd like to learn more about modifying them for faster take offs

I bought two of these Twister HammerHeads in June. I've only ran them about 10-15hrs. (at most) this summer. Although, very hard racing hours.. and the only problems I've had so far "knock on wood" is the bolts loosening. Hell I even rolled one upside down and rolled it back over and drove it back.
So far I've been impressed with them, but the only complaint would be the take off power.. you're not going to get a hole shot out of one of these stock. But then I have a 15y/o and hopefully he'll learn a lil' bit of driving technique and get the wild driving out on these and not on the street.

GUYS! sorry to break in on your thread.. but I'm trying to fix my Twister for the weekend and getting frustrated.
My drive belt broke on the engine and I've got the replacement in today and now can't figure out how to get it on..
The engines consists of a engine side and clutch side... the dealer mechanic said pull it off on the clutch side.. but the engine pully looks like it splits in two.. either way the problem I have is getting the bolt loose on either pully without the engine or transmission turning over, not much to hold on to there.
ANY IDEAS WOULD BE GREATLY APPRECIATED.. THANKS!!!
Posted by: 4wheelhi
I have an impact gun...
which pully should I attack and how do I stop it from spinning?
Thanks!
Posted by: 4wheelhi
COOL.. I"m on it..
I have an electric and a air impact... that makes since about what you're saying with the torque...
So I'm assuming since you mentioned the engine turning.. I'm taking the engine side pully off not the clutch side pully?
Thanks for the advice.. .please enlighten me more..!
Posted by: 4wheelhi
Okay... what a mess
I took the fly wheel off the engine side and of course the inside of the flywheel (pully) fell apart. After getting that back together.. I'm stuck now on how to stretch the belt over both pullys.
Any ideas there?
thanks again for the insight

I bought a Twister Hammer Head 2 about 2 months ago. Last week the starter went out. I took it back to the dealer and he said that was the 2nd one to go out. Keep in mind this dealer has only been selling the karts about 2 months. I got one of the first he sold. The mechanic in the back also told me 2 had come back with blown engines and almost everyone of them come back with the reverse cable broken. He said mine was about to break but he didnt have any spare parts in inventory. He said I should change the engine oil every month. Anyone else having trouble with the Hammerhead 2?
Thanks Eddie

They assemble them but I would think the engines would come assembled so the engines blowing up and the starters going out should not be from the assembly I wouldnt think. I am thinking its the cheap Chinese made kart

Mine has not been abused. Only putted around with my 3 year old in with me. I have proably put 2 tanks of gas thru it.
Posted by: pedullabass
yes the warranty covered it all.

hey Kell email me eddiecma@bellsouth.net I live in Marshall County just across the line from McCracken. I bought My twister in Cadiz for $2600
Eddie
Posted by: pedullabass
Yes now it seems to have a charging problem. Seem the lights run the battery down. I think I got one of the first 6 at Cadiz. He said after the first 10 the price was going up. Mine has the tires like the link you posted and has horn and turn signals.

I havent tried to do anything with the seat belts. He told me at the Cadiz store that some people duct tape them. I also drive my 3 year old around. There are trails back where I live on Little Cypress Rd. off of 62 first road to the left into Marshall. back on the Tennessee River. I also have 4 Military Jeeps. opps I mean 5 I cant keep them straight.
Posted by: pedullabass
Theres some close to the river , some dirt roads thru crop land. A few trails in the woods, but you have to drive on the road some to get to them.

Hey Kell Im still here. Hardly ever mess with the Kart. I did change the oil the first time last night.Too busy restoring 3 WW2 jeeps and 2 viet nam era jeeps.
What have you done to your Kart to make faster. Where id iyou buy it and how much.
Thanks Eddie

Hey Kell the guy that sits beside me here at work said he saw you at Turkey Bay saturday. He rides motorcycles. I got most the problems fixed on my Twister finally.
1. the plug wire was lose on the spark plug.
2. the rectifier was not plugged in so the battery was not charging.

Yeah I noticed the changes the other day. I called Direct to try to upgrade my air filter but no luck. Classics told told me to call Tweister direct becasue they would prob want to upgrade my air breather for free since they had had so many engines blow up. I called and ask them and they told me that isnt true and they would not sell directly to me.

I purchased a Twister Hammer head a month ago,
after 2 hours the reverse cable broke and the motor blew up, bad piston casting.
They sent me another piston and gaskets
after 1.5 hours the engine went again, same problem with the piston
they say that they have an updated piston design and are sending it to me,
if it goes again I will use the lemon law...
The cart is basically a good design and well built, The motor is a copy of a Honda, down to the color code of the wiring.
Posted by: DuneCountry
What happened was that the lower oil ring land gave way just above the wrist pin on both pistons, there is not much support there.
I took the barrel and pistons to my machinist who does all of my engine work, (I have 17 rental quads)
He mic-ed the pistons and found that there is no camber in the skirt. The skirt should be .007 to.010 narrower than the dome, he showed me this with a Wiesco, What he figures is happening is the side thrust is causing a problem.
When I explained this to the seller he said that the importer had just received a new/different batch of pistons from the factory.
Might have just been a bad batch.
Posted by: DuneCountry
Yes, we have discussed boring it to 180cc and using a wiesco.
The problem is that we only have 3 hours on a brand new machine,still under warranty, the seller might opt to cover my costs though
Posted by: DuneCountry
Nobody makes a stock replacement for a 150cc, we talked about boring it out to 63mm which would make it a 185cc, using a honda style piston, if the pin to deck height is the same.
compression ratio would be stock,

We always wanted to do something fun,
But even this has it's hassels

Posted by: DuneCountry
Thought I would post an update.
The third piston failed, again after 2 or so hours.
We removed the engine and sent it back to the importer on Sept. 28th. Still haven't got it back.
I have been doing some measuring and it looks like a Polaris 250 engine and trans will go right in with a few mods.
I called the importer yesterday and told them if they refund me $500 they can keep the engine.
Have yet to hear back, but I am going to start on the re-fit.
I will keep you posted.

I would like any more info anyone has on these go-karts, I am considering selling my new Honda 450r and getting one of these so I can drive my son around. Is the suspension decent? the rear suspension has the engine on it, can it climb moderate hills such as getting out of a creek bed? Will we take a beating riding down average trails? My brother has a Rhino and that thing can literally go anywhere, I would like to be able to follow him at least some of the time, I know ground clearance may be an issue but I am mainly wondering if it has enough power to climb hills. thank you, Kell
Posted by: Kell
Thanks, thats just the information I need. As soon as I sell my 4-wheeler I will probably end up buying one. It just looks like a cheap way to have fun with the boys. Now if there was just a way to bolt on your R6 engine! I was curious, you must have the single seater, I would guess the double would be heavier. I had looked at the yerf dog at sams which was only about $1600. I talked to someone who bought one of these and said they did great but he was looking for bigger tires in the front to get more ground clearance.
thanks again for the input,
Kell
Posted by: Kell
Well I went ahead and bought one at Gander Mountain, $2700 with discount so it sounds like
I paid a little too much. Another local dealer had the 2004 model for $2750, after a little research I found out the 2005 had a few updates like tires and more grease fittings. I can't wait till its broke in, I think its going to work great for me and my oldest son. could use more power and more suspension but exceeded my expectations. Went through some pretty gnarly ditches and easily does donuts in gravel and grass. I haven't been able to really punch it but doesn't seem like there will be a whole lot of power there. Just barely fits in the back of my small toyota truck (have to back it in and leave front tires sticking out).
So where do I find the pipe and jet kit for this? Does it help any? Will it fit the twister? It does not have the backup kick start like on some others, electric start only.
Can someone tell me what the heck I need blinkers and a trailer hitch for? I like the lights and rearview mirror but comeon, its not nearly fast enough or powerful enough to drive on the road especially with a trailer!
All in all I really like it and can't wait to get on some serious trails with it. It seems to be geared low enough to get through some tight stuff and pretty steep hills. Going through some rough stuff, it just picks up one of the front wheels and keeps on going! My son is better protected than on my brothers rhino also, It has better seat belts and the frame wraps around the riders. Really nice seats also.
thanks to everyone for there input!

So does the pipe give it any more power? Since you need torque on these CVT type machines I would be worried it takes some power off the low end and puts it all on top. I am considering ordering one just for the sound though!
My cousin put a pipe on his yamaha 660 utility quad (kodiak?) with automatic with no increase in power. I know on a regular quad that you control the clutch on a pipe can make a huge difference.
A little more suspension and power and this would be a blast to race! Ive already got a set of flat track tires on rims that will bolt right on for tt racing! Not sure how much jumping you could do in stock form, but I'm willing to try it.
Also, I could not find the Toy Junkie place where someone ordered there's, I did a search and came up with nothing.
Kell
Posted by: Kell
Yeah, a 10%-15% increase on 10hp wouldn't feel like a whole lot. I'm ordering one anyway.
Has anyone had problems with their chain Breaking? went to the dazon forum on some sandrail site and they where dogging the twister and kpx's because they only have one chain and they say they break alot. Not sure how this would happen, maybe if you jumped it with too loose or too tight of a chain?
Anyway I am sure you guys think I'm nuts for posting so much, just never knew a go-kart could be this much fun!

Those look like they'd work much better than the stock ones that came on my KPX's. What size are they?
My tires say 22-10-10 on the side, look the same size as my Hondas, I think they are taller than last years version, this may make top speed slightly higher. They do a nice job of tearing up the bermuda grass I call a lawn. Also I like the square profile of them, I think they have too much air in the one in the picture because mine look perfectly flat on top. I will be testing them out this weekend hopefully on some real trails. I am not sure if I should change the oil before then. I only have 45 fairly easy minutes on the engine but want it to last. Someone said the stock oil was pretty wimpy. I doubt I can ride it for much longer without getting on it, especially in the woods. I told my wife if this one is as much fun in the woods as I think its going to be I may order a cheaper (and lighter) single seat version but she said if I do that she wants one for her and our other boy to ride in.

Allright, so where do I get the yerf dog head?
this is going to get expensive before long.

Here are my experiences with the Pipe and jet kit/uni air filter that East side sells.
I put the pipe on this weekend and didn't have time to put the rest on because I was anxious to try it out anyway. I noticed an immediate improvement in low end power. It definetly had more grunt, not much added on top though. All of the screws on the back of the pipe were loose and I lost one. The pipe looks professional, the part that replaces the stock air system is pretty crude looking but I am into performance not looks.
Saturday I put the jet kit and filter on. The jet was a 145 and replaced a 108. Now the buggy seems a little slower again, also smokes now and the plug is black. Is there anyway I put too much oil on the filter? I squeezed the excess out with paper towels. 145 seems like a big jump to me. Can I find these jets locally? thinking of trying a 140 or 135.
Took the buggy out a couple of weekends ago to Turkey Bay which is an excellent off road park, maybe a little rough though. The buggy did good, had some trouble climbing steep hills. I did manage to bend the bar thing that sticks out of the strut/kingpin? that attaches to the end of the rack & pinion steering. Came off a pretty large jump and landed on one front wheel. Pretty harsh landing! All in all the buggy did very well, almost impossible to tip over (so far).
A few more things, the stock air filter is worthless, you can see the dust getting by this into the air system. My oil was filled too high also causing some to come out of that tube the other guy was talking about.
The last thing, I went ahead and bought castrol syntec 10/40, do you guys think this will work well in this?
thanks for the advice,
Kell
Posted by: Kell
I checked and our elevation is around 400'
Not sure where to find the shim material, I don't have access to pilot drillbits either. Do you think I can pick up a jet that fits from our local bike shop? the carb says made in japan on it. When I ordered the pipe kit, they asked me my elevation which I didn't know at the time. I don't want to wait another week for them to get me another main jet. I guess a set of drillbits would come in handy though!
thanks for the input.
Kell
Oh yeah, had every kid in the neighborhood riding in the cart this weekend, and when I unloaded down at turkey bay there was a crowd around the twister but no-one around my bro's rhino. go figure?
Posted by: Kell
Mine has a 145 which must be a mistake, probably meant to send a 115 or something. Already did away with the stock airbox, now has a unifilter.
eddie,
are you still having trouble with yours? I called the guy in cadiz and he said he wouldn't come off the 2750 price so I went to Gander and got it for 2700 (before tax). My thinking was that theirs would probably be the newest version with the good tires. If I had known about the KPX's I would have ordered one of those, I am not big on the cheesy blinkers and horn on mine.
First time in lbl and the very first jump, about 3', it did a nosedive and landed on the front of the frame. That was quite a painful lesson. Dead stop, with lots of dirt and gravel covering me and even making it up under my goggles. It just doesn't have the power to pick the front end up enough to land level for a steep jump. I thought the suspension held up pretty good though. Its not something I would do with my 3 year old in it anyway.
Kell
Posted by: Kell
I am sorry to hear you are still having problems. I like to just go out get in and drive, like my toyota truck. Have you solved the problem with the seatbelts? Mine just vibrate until they slip and get really loose. I put my 3 year old boy on a booster seat so the belt fits better. thinking of duct taping them.
Is there anyware close that has some trails? I live in Reidland and when I drive east on I-24, near the waterskiing place on the right I see trails sometimes. Somewhere between husbands rd. and Exit 16.
I have to back this thing up into my small Toyota truck, one wheel goes over the wheel well and the front tires stick out on the tailgate. Looks pretty funny going down the highway!
Kelly (yeah, I'm a dude not a chick)
Posted by: Kell
Allright,
I jacked up the backend of the Twister and oiled the chain with the cart running (wheels moving) and noticed the reverse gear assembly wobbling. Has anyone else noticed this? Looks like the shaft is fine, just the whole housing wobbles. The sprocket looks pretty good so I don't think it is making the chain tight and slack.
Eddie,
Are these trails on the river? Hills and stuff? I may have to come check them out sometime. Got to get another jet from FDR today. Think I'll try a 135 since it runs better with the 145 than the 108.

Here's my latest update on the Twister buggy with pipe and jet kit.
Sort of got the jetting about right and took it for some serious creek riding with my son.
I am really impressed with the increased hill climbing ability that the pipe gave it. It has
a lot more low end grunt, right where you need it. It did almost nothing for top end, so
top speed is still pretty slow, I would guess around 30-35.
Got stuck in the sandy/rocky creek bottom a couple of times. Its really soft and the buggy
just dug right in. The fast sections where a blast though. My butt got wet though going through
the wet sections. I didn't want to go in too deep water because of the transmission. Water
came flooding in on top of the floorboards, my son sits on a booster seat so he didn't get wet.
Probably the deepest was a foot or so. The taller tires on the 2 seat version helps in this area.
Also, most of the hills have ruts so a taller tire helps keep the sprocket and brake from dragging as
bad.
So far it's holding up fairly well. When I first got it I did some stupid stuff like jumping it a bunch
and now every one of the wheels slightly wobbles (could have been this way from the factory though)
Some things vibrate loose, lost a grease fitting, rollcage needs tightening every once in a while.
SMOKES LIKE CRAZY when I start it. After it runs a little bit it stops though. I guess oil is leaking past
the valves or something, not used to seeing the cylinder layed over like that, maybe that has something
to do with it. Still needs lots more power though. Wish I could bolt on something with a CVT transmission
that wouldn't require too much fabrication. Looked into getting a whole 250 chinese quad and just
taking the engine off, that may be a fairly inexpensive option.
Anyway, I had so much fun I am thinking of getting the one seat version.
It should be quite a bit lighter. I would take the rack off, maybe get some aluminum rims,
cut any excess metal off the frame. Looks like on the single seater, you might be able to remount
the front shocks for more travel. I know on ebay they are selling for about $1400 plus shipping.
that sounds like a pretty good deal for cheap fun.
Kell
Posted by: Kell
Raptoraz,
Do you think the Yerf Dog head is worth looking into?
I would like to get a look at the 250 engine they are putting into
4-wheelers and see if it would bolt on fairly easily. I guess the main
problem is the sprocket needing to be where the pivot is.
thanks,
Kell

Oh yeah,
does anyone know if the rear bolt pattern matches up to anything else?
I think it is a 133? that sounds pretty oddball. the front is 110
thanks

The 4x133 pattern is the same as the Kawasaki Bayou. Which limits your wheel selection. I've found that the easiest way to convert to a more common pattern is bolting on a set of Raptor/Banshee/YFZ hubs. Which have the same splines. Making the pattern a 4x115. They can be found on ebay for $15-25 a pair.
Checked on ebay, they look kinda pricey.
I may try locally.
Will probably just drill out some existing rims off something else. Ive done it before,
just print out on computer and mark centers with punch.
I guess I'll start chopping weight off the buggy for a big ride they got going on for this weekend. Goodbye rear rack. Not sure if I will take the fenders off, they didn't seem to do much good in the creek but may work for the mud.
Posted by: Kell
That rollcage cracks me up! looks like one of those toys that when it rolls over, it rights itself!
It also looks a little bigger and heavier. I like the size and turning radius of my little buggy. I'll just have to do a few more mods to keep up with the faster atv's. I probably have as much fun tinkering with it as riding it. I am sure that in the near future someone is going to start racing these and then we will have all kinds of hop up kits and longer travel suspension etc. Maybe raptoraz should start selling head kits, I know I would buy one if it came with everything I needed in one package. A bigger cylinder/piston/cam/head with pipe, jet kit etc. would be nice! I am not sure how much power the CVT can handle, I haven't heard of anyone with problems yet. I know the polaris scrambler has a similar 2-stroke setup in there 90's, it would be nice if they had a 200cc 2-stroke that I could bolt in. You can get a lot more power out of a 2-stroke in a smaller package, and they are easier in my opinion to work on. As it stands now, if I ran into major problems, I could probably buy an entire kids 150 atv shipped to my door for a little over $1000 and yank the engine out and put in on my buggy.
Hey eddie, you still hanging around?
My brothers are going to Paddy's Bluff this weekend.
http://www.paddysbluff.com/
I've never been, so I am not sure how muddy it gets. I hope the pictures where taken on a really muddy day! Anyway, I think they said they were going Sunday after church if you want to try and make it, it would be nice to ride with another twister.
one more creek picture showing my oldest (this is one of the shallower crossings before getting my rear end soaked)

other end is a hose union and spring clamp. Exiting the top of the
trans case is a similar vacuum hose. I connected them during
reassembly but it created an enormous amount of positive pressure in
the crankcase to the extent that after 10 minutes the exhaust was
blowing blue smoke from blowby and when I opened the dipstick tube
the oil blew all over the engine.
SHould they be connected and if so, how does the crankcase vent?
Sitting here at work on the computer I am trying to visualize what you are talking about. I think, (I'll check for sure later) that the one that comes out of the front of the head just vents out towards the back, NOT CONNECTED TO ANYTHING. I think mine lays on top of the transmission and burps out oil every once in a while. I am pretty sure that you SHOULDN'T connect them. This would probably build up a lot of pressure like your talking about.
Hope this helps

bedo
If you could tell us what exactly you will be using the cart or carts for then we could probably answer better. I know that I probably wouldn't want to do any serious riding with 2 adults in my Twister buggy, even with my upgraded pipe kit and air filter/jetting. It's a little underpowered for hill climbing. Don't get me wrong, I love my buggy, and the pipe definetly helped in the hill climbing department. Not sure I would go to the trouble of trying to modify a CDI for it.
You might want to look at the independent suspension 250's they are selling on ebay. They look a little more complex, but if ride comfort is what you are after, independent is the way to go. I prefer a solid rear axle for super fun cornering and sliding but to each his own. I do know my buggy goes places and climbs things just about as well as an ATV and it does it in a safer somewhat funner manner! even with the little motor.
good luck!
Posted by: Kell
Yep, I'm 100% sure now, I checked it last night. It just lays there belching out oil periodically. The other vent tube does look kinda funny, has some wierd bends in it.
Was it hard getting parts for the KPX? I'm sure I'll eventually tear mine up!

Posted by: Kell
The easiest and most accurate thing to do is mark you tire and roll it across the garage measuring distance the tire makes in one rotation. Convert this to metric by multiplying your inches by 25.4 to get mm, for example 50.25" x 25.4 = 1276. this is usually the number you enter into the computer on bicycle style speedometers. check your manual to be for sure. I think this is the number for a 16" bicycle tire.
I think I am remembering this right?
