well thats one opinion.

You might try a filter/jet kit with an aftermarket pipe. That will get a little bit of it back, but you're always going to have a decrease in power with the larger tire setup. The traditional sacrifice one thing for another scenario. You're also going to have a lot louder quad if you were to go the pipe route.

But I bet those tires look pretty good though!

My opinion is that if you have the money for it and you want it, get it.

I had 27" tires on my 99 AC 500, and while it did take away a little of the power, it didn't drag it down hard by any means. I say just stick with it, and you will get used to it fairly soon. You got the tires for a reason. Remember that reason.

As far as all this "Don't buy something you don't need, and think first", well hell, thats hindsight 20/20 and so is life. Forget that crap. Unless your family starved because you spent the last dime on a set of tires, then you don't have anything to worry about.

It is when you are in your 60's, not when you are in your 20's or 30's. What is money? Freakin paper unless you use it. You aint takin it with you. Why the hell do we own and ride these things??? Seriously? For fun, for amusement, to enjoy. If putting chrome rims and lift kits, pipes, gun racks, brush guards, 28" tires, auxilary lighting, tube bumpers, or any of that stuff on your quad makes it more fun to enjoy by any means, then thats the point.

His quad isn't ruined because he has a set of 27" tires on it. There are a ton of 500's running around with the same tires and the folks that are driving them are probably having a pretty good time with them.

Performs worse? You mean you can't drag race with it? Well hell, not a whole lot of AC 500's winning drags very often anyway. The quad will pull the tires, it will perform much better in mud and snow. It won't hang up on rocks as much with the increase in ground clearance. And it is by no means overburdened by the larger tire size that it is not every bit as capable in every aspect of riding it other than acceleration. I had an AC 500, I had 27" Tri/Bi-Claws on it. They are heavier than 589's. Mine never suffered. Yes its a little slower than stock, but it did not bog down under a load, and it destroyed the mud.


This guy asked a question about modifications for a power increase. I seriously doubt he was asking for a lecture on the negative subject of accessorizing, cause and effect, or the moral ethics of being stupid and wastefull. To be honest, he hasn't got much for $hit in the way of answering his original question so far.

That would be a pretty expensive change.

You can get a new filter and rejet the machine. An exhaust system would help too.

Well thats nice but it doesnt do this guy a lick of good now. Not everyone is content to buy only what they need. If that was truly the case, most ute owners would have a 250 like you. The best we can do now is try to help him, instead of suggesting that he take a few hundred dollar hit on changing tires again.

Not everyone thinks before they purchase these things, and its not like purchasing tires from a dealer who knows whats best for your car or truck and what it can handle.

Besides, big tires look cool!!!img src="i/expressions/face-icon-small-wink.gif" border="0">

Andy good, bear, bad. Bad bear, bad...

There was a guy on highlifter running 29.5 laws on his polaris 500, maybe bear could go there and yell at everyone too...

Yes, it is not the best idea to buy tires bigger than you need from a power standpoint. However, since splint is only asking how to get back some low end, and not whining about how terrible the power is now, I think its safe to say that he didnt go too overboard.

The point of this post is to help splint. If you dont plan on doing that or telling him how to get help, then I suggest you just leave this thread alone as your responses are not positive contributions to the thread.

I thought the 500 was an auto clutch? If it is a belt drive, then new primary and secondary springs will make a big difference.

Posted by: maddog56

Why does he need to go back at all? He didnt say his quad is unrideable, nor is he really even complaining. He just wants some more low end to go with the tires...

27" tires on a 500 does not cause that bad of a power loss. I ran 26" mudders on a rancher 350 and while it lost power it made up for it ten fold on traction and off road ability.

Posted by: maddog56

You seem to be the only person who thinks he screwed up. A little self righteous arent we...

I'm done with this thread, I've given all the useful input I had. Good luck on your search for more power splint, and sorry this crap had to go on in your thread.

No offense man, but that looks like a lie to me, since according to the forum this was your first post...img src="i/expressions/face-icon-small-wink.gif" border="0">

BTW, I said I was done with this thread and I am. I'm not getting into it with bear again.

But this stuff is bull, and it should stop.

Notice the smilely face and wink? Joke my man, joke. But I agree that this stuff isnt good for the site.

when i bought my arctic cat last year i ordered the biggest tire i could find 28x12x12 28x10x12 gators
and i asked the dealer if it would effect the performance of the quad,and he said it shouldent make that much of a differance.
the reason i got the big tires was because speed did not matter to me and as for power i thought the 500 had plenty of power plus it was a manual also.
so i thought if i need more power i always had low range.
i expected it to have a slight power loss and im sure splint knew that also when he got his tires.
i know he asked the question about it on the forum.
because i remember replying to the post as did a few others.
when i got my new rubicon in may i orderd 26" mud lites but it wasent because of the lost power, it was because the 28s were to hard on parts.
if i knew the honda would hold up to 27s or 28s i would have put them on but i was scared of what happend to my cat and i cant afford any more problems so i went with a smaller tire.
my friend has the same quad and he has 27"mud lites on his and he hasent broken any parts on his.
YET.
and if his is still going when im ready for new tires i just might go to 27" next time.
but splints not complaning about the tires he just asked what he could do to get that bit of lost power he had back.
i think thats what you called reserching befor buying.
he did the reserch on the tires and got what he wanted for mud and snow performance.
so now hes resurching the engine performance part of the quad.
so lets help him out insted of beeking off to one another.
i agree with the others a jet kit and after market exhuast would help with the power loss.
i dont know about the filter unless its a performance foam filter.
i heard that the gause filters(K&N) dont stop very much in dusty conditions.
and that is hard on the engine.
hope we did scare you off.
ive had my share of disagrements on this forum and im still here and i will be for a long time comming.
and im sure we"ll disagree again but untill then.
im agreeing to disagree.

ride often and have fun thats what its all about.

Splint, do you have an auto or a manual tranny? If it's an auto definatly look into a clutch kit. For more power get a pipe and jet kit. black magic racing has a good pipe, they say it adds 6-7hp at the crank, 30 is stock.

Go back to 26" tires that will lower your gear ratio back down and not kill your torque.

I have a short fuse when it comes to people doing mods on their rides and not knowing what they are going to get when you do the change. Do your home work first, it's cheaper and you end up with something that works. As to being satisfied with factory, not even close. I have never owned any vehicle that stayed stock. I have also been my own race team and set records and won regional, divisional and even National championships with mostly outdated equipment by getting everything there was out of it. But I do research before I buy or change and it does not help to just spend more money to change other things to cover what you screwed up. You need to get smarter. If you can't stand the truth, don't ask the question. The truth is don't change it unless you know what you are doing and definatly don't change it cause someone else did it. Most guys are riding to their machines to their full potential when they start doing mods. Learn your equipment and get the most out of it before you start changing things. The only way you will now what needs changing is to ring out all there is in your machine and then see what needs changing for your style of riding. Read my signiture and those things are the truth.

Andy; It is not only wasteful but stupid to spend money modifing something so that it performs worse. Why not just dump water in the gas tank, which would be free and have the same result. It's not about how much you spend. It's about spending what you do wisely. Making it work better is the goal, not screwing it up.

Posted by: Bear4570

Andy, We have had these discussions before and you and I basiclly agreed to disagree. But drag racing isn't what quads are mainly about. Oh yeah, don't be pushing me into the 60 year old bracket any faster than I'm getting there. It's comming way to soon anyway. However I grew up in a very upper middle class family with a lot more money than the average family had in the 50's and 60's. Hell, we even had a pool by the time I was in high school. So I didn't learn smart, money and time investment from my parents. I learned from experience of myself and others (that's the one that cost you nothing, learning from other peoples mistakes) that the right way and wrong way to do things and the right way makes for a less work intensive and costly project. You don't become a winner by being wasteful and stupid with your time and money. I have been a winner since I was in my 20's by using the smart part before the money and muscle part. If you do more with less, then you have more to do other things with. Works for both time and money.

Maddog; Yes "Bad Bear" is another nick name I've earned over the years and I'm to old to change now. All I was trying to do was get people to think about what they are going to do before hand. Cheaper and easier and less stressful. Also why can't he go back to his original tires until he finds they power(not likely with out more major expense), they can't be wore out unless he's a pavement pig.

Posted by: Bear4570

You guys really don't get it do you. If you go thru life not learning or learning from others mistakes you are just going to continue to be a loser and waste your life accomplishing nothing. It's a shame that the liberals of world have convinced you that it's a no-no to hurt someones feeling. Well get real, that's whats wrong with the world. Guy #1 does something stupid; guy #2 says you did bad(the truth by the way) and you attack the truth teller and defend the wromg doer. No wonder the world is more full of them than ever.

heyyou; You sound like the pot calling the kettle black.

Posted by: Bear4570

Mudblaster; Just think how boring life would be if everyone always agreed. After a week you'd want to blow your brains out just so you could at least disagree with yourself.

my friend has a 05 500 he put 27x10 589s on it noticed a little power loss so we put a dynojet kit and a epi secondary clutch spring it made a huge difference he throws rooster tails of mud off all 4 tires i dont know where you guys ride but up here in mass we got some swamps and deep much and ground clearence and aggresive tires are needed i think the dynojet kit was 45.00 and the epi secondary spring was roughly 35.00

I have the Highlifter module on my 650,Do they make one for your bike?It'll help out your low end torqe.

Posted by: heyyou

Splint,go to ArcticChat.com,there are tons of guys there that will be happy to HELP you,and not call you dumb.

Posted by: heyyou

Yeah,getting a little crotchity in his old age,lighten up.That doesn't help at all.

Posted by: heyyou

It must be great being born with all your smarts.Or did you listen and learn from every hatefull old SOB that grilled you on your stupidity??No,I'll bet you were a lot like every other red blooded boy in North America and told him to cram it with walnuts ugly,and did it the way you wanted to in the first place.THATS the way most people learn,by doing.Not listening to hatefull old cuss's that really don't want to help,just complain.

Posted by: heyyou

LOL,yeah ok,apology accepted.

Posted by: weez440

wow i have never seen anything like this before the poor guy just asks how to gain back some power for putting 27 inch tires on a 500 pretty it is claimed he wasted money and lol all i gotta say is wow i had a 2003 500i and had 27 inch tires on mine the exact same ones and they were NOT a waste people do different kinds of riding and my style required oversized tires enough said. did i wish i had more power out of my 500 yeah of corse i did things like that run in my blood i am always wanting more power i can't see how you can consider him to be stupid for wanting more power i don't care bear that you grew up in an upper middle class home or any of that he didn't ask for that he just wanted simple explanations on how to get more power which some good people gave him good idea's so we should maybe all just WOOOOSAWWWWW and have a coke and a smile

Posted by: splint

i jsu bought 27 inch 589's and have lost some power
i was wondering what could i do to gain power in the lower gears

i noticed that bear4570 always bits someones head off when they ask for advice

Posted by: TheShockDoc

Isnt easier to say "I don't know", than to bust the guys nuts? Sheeeesh!


I don't have experience with your machine, but in general, do some research on:

Clutching- when looking for a clutch kit, be certain of what you DON'T want. If you rock crawl, you certainly don't want to have a high engagement. Consider driveability, and what type of riding you do. Ask the manufacturer, when in doubt.

Airbox mods: Again, research what you can do without killing another aspect. Drilling additional air holes in the top (Before the filter) will allow it to breathe better, but the water fording capabilites may suffer. Will just a high flow filter work?

Camshafts: Available for your model? Maybe. Will it do what you want? Maybe. Research.

Carburation: Is your bike jetted properly for your elevation? Plug readings? Do you go up/down large elevation changes? Winter riding? It all effects jetting. R word.

Exhaust: Buy or modify. Sound level important? Find out before, and does it make REAL power or does the noise "make it go faster"? Research.


Now I KNOW you knew this, and were looking for a shortcut, to see if someone already did it. Looks like from the responses that no one has. About an hour of Google search, and searches within each site will yield your answers. Its a shame that some guys have to go off the deep end though....

1.) I am no liberal, BY ANY MEANS. If you believe being POLITE is being liberal, you need to re-evaluate life.

2.) No one is defending him at all. Go pout in the corner. I feel that I represent most posters that you don't need to GO OFF on a guy, because he wanted taller tires, and bought them. REREAD his post. He's looking for more POWER. If you can't tell him , then go to another post.

Tact goes a long ways. Not everyone has "climbed the mountain".

What have I accomplished? Hows a 9.72 pass on a SNOWMOBILE on Asphalt at 135 mph on PUMP GAS? Try 4.92 @ 118 mph in 500' on ice? 8.92 in a Big Block Vega at 161mph? I own 2 business's. Big Deal. Its not germaine to the topic. This is all about 4 wheelers and a guy looking for more power.

Posted by: frndinalowplace

so i guess bear would also disagree with putting 40" swampers on a raised pickup as well. thats some serious power loss. im not saying your wrong bear, there have been plenty of times ive yelled at someone for what i thought was a waste of money. but u have to look at both sides. ya he lost some power but what did he get in return- more ground clearance+more traction. Im sure that outweighs the negative part especially now that he probably got rid of the chance of him getting stuck as often like his stockers, i know i get mad when i get stuck and all the headache that causes. besides he just asked how he can offset the loss of power, he wasnt crying that he lost some power, if he was then you can yell at him all you want because he was ignorant to finding out the consequences of larger tires.

p.s. does anyone else think that bear reminds them of that one guy that was on monster house- that carpenter named doctor wood that got on everyone's nerves because he thought he knew better than neone else. just a thought

seeing as I have a 500 and wanted to do some performance mods I did some research and all I can really find for them is jet kts, pipes, clutch kits, and filters no igniton module, or anything else (I figure maybe 5 hp and a little better low torque with all that). not sure if it is possible but maybe you could have the head shaved to bump the compression and run a little higher octane or go to a bigger bore maybe a port and polish, but that would be rather expensive and a pain but if you really feel you need the extra HP it may be worth a thought.

Posted by: pangborn83

hate to put in anything else but here is a few links I have found in the quest for more power http://www.highlifter.com/store/High%20Performance%20Kit.html for a jet kit, pipe and filter, a link for a article about the muffler mod (suppose to be quieter than a aftermarket the way I understand http://forums.atvconnection.com/messageview.cfm?catid=5&threadid=340310&highlight_key=y&keyword1=muffler&keyword2=mod and a link to a home grown tranny trick http://f1.pg.photos.yahoo.com/ph/fangoelgato/album?.dir=/7c4d&.src=ph&store=&prodid=&.done=http%3a//f1.pg.photos.yahoo.com/ph/fangoelgato/my_photos a couple of cheap alternatives there at the end and a more expensive at the begining but it all depends on your budget and the time you want to spend

Boy, I'm glad you pointed that out! I am indeed wrong here. I made that post on "another site" where I still make the same observation. So I was in error when I started questioning that judgement as related to this site. I didn't make the statement her in the first place so I wouldn't need to retract it. But that still doesn't change the fact that I think all the "crap" in these kinds of attacks are detrimental to the site. I have gotten some very good information from this site in the past. But I still hate wading through the "crap" to find it. Maybe what I just wrote is even "crap". SORRY! So I'll quit!
