There is not one on the 04' for sure. The problem lies with Yamaha's cdi box. We had one and got rid of it since we could not do anything to make it a better quad. Since then I believe raptor80racing.com has some fixes to make this a better machine. You might check with them. Good Luck!!

A little caution here... although I don't think you can modify the machine to the point where you might have issues with safety, I just want to make sure you think about what you bought the machine for in the first place.

The 50 is definately a snail... but that is it's intention. It is desigend for young riders to be a training machine to teach them the fundamentals of riding without giving them too many mechanical things to worry about.

If the child has progressed in skills, you might want to consider upclassing if you can do so and remain legal. You should have no problem selling it for nearly what you paid for it if it was maintained. Plus, upgrading a machine to gain only a couple MPH can turn into a real money pit.

ok hears the deal one yamaha is only leting your 50 cc machine carb open have way so one go to raptor80racing.com and get a jet kit 2 cut the slide valve so it will open all the way two get one of 2 cdi boxes availble form r80r.com 3 get a header and pipe and kandn high flow airfilter 4 race shocks 5 off set wheels and tires then watch this little snail keep up with a 660 in second gear high oh yeah widing kit to really helps and the tires are bigger and run on less air pressure so its works out great the real deal is the carb its only opening half way talk to the guys at raptor80racing.com
so there you have it all the info yo need to make a 50 or 80 run like crazy p.s. if you want to see it run like a bat aout of hell take 8 out of the 12 roller balls in the tranny lighting it and make the top end higher to get it to grab lots of power to be hade just have to know how to get to it oh yeah i think you can geta 4 speed tranny from the 80 to fit a 50 not sure yet looking in to it good luck and by the way 50 cc in a yamaha is a 50 cc in any other machine
cool later happy riding

draggin but i just posted about what to do we are getting twice what yamaha says there geting plus were not done and yes it can be tweaked to a unsafe speed trust me were useing the lesser of the cdi boxes availble and it keeps up with my 660 in second gear that aint no joke i could get hurt in second gear let alone the kid on a 50 at that speed just takes some looking into like the 16 milimeter carb only opening 8 miliameter thats really gets the led out allright safe riding every body

Everyone says that the 50 is a learning stage quad and that is true. The problem is that a 50 Suzuki and a e-ton or any other machine will do 20 miles an hour and a top dollar raptor 50 does 12 mph. That is sad and so I see no reason why someone wouldn't modify this quad to at least stay close to the other 50's. I am sad to see how slow this quad is. Not only do you pay top dolllar for this machine but you need to buy a aftermarket cdi box just to get a decient top speed. Yamaha should have just let the parent be the judge of how fast we want the machine to go. Now we have to pay 100+ for the cdi box and 250+ for the exhaust just to get the thing to move as fast as a cheaper e-ton or any other normal 50. I think that is BS and Yamaha should warn people of this before you purchase it. I know there are some people who made a big enough stink, that they ended up taking the quad back. You pay top dollar for something, so you should get what you paid for. What should I expect to get on the top end with the procom cdi box and the slider in the carb opened all the way? I hope by doing these two things, I will get it to 20 mph. That is all I am looking for. Not asking a lot here and of course I wouldn't do this if my son wasn't a smart, good, well rounded little rider. Also, if I put the bigger tires on it down the rode, what will I see on the top end? What size tire and rims are we talking about? Thanks!

mmade well put for sure but at the same time those two rides you mentioned are not really in the same ball park one the suzkie is a two srtoke pull start ( bunk ) two it sits wierd and not shaped right interms of rider fit i looked at both those machines and bought my son the yamaha fully knowing what yamaha was holding back, big time and allso knowing that there is a ton of goodys gona put them on dont matter what quad he got. plus heres another tip the 80 cc rig parts motor and trans will fit a 50
plus theres a hot cam for that 80cc rig plus the 3 speed shifting automatic tranny and bigger carbs and plus i'v seen two with blaster front ends welding and fabed on one a 50 and one an 80 really cool rides now yes i'm yamaha biased but hey nice rides best i can tell . and interms of what you should see on top end like i said wiht what i did wiht my sons 50 it keeps up with my 660 at just below high 2nd gear plus much better rev liminter not so bouncy real smooth thats nice the tire size differnce is allmost i think 2 inches in widths and 1and half in hight the killler thing i liked right away was the widing kit with the off set rims the quad really hadles the ruff stuff plus it alot easyer for my son to turn the wheels but in the end i'm doing a blasterfront graft for indepent front end and then a 80cc motor with a 90cc bore out and new piston and new cam and the 300 dollar cdi box soem nerf bars and new racing handle bars by the time i'm done i'll have a real littl mini raptor and in closing thats why i like the 50 or 80 cc machines all that i have explained aint happing with e-ton or suzkie sorry just my cent and half

ok found my invoice heres the wheel sizes 2 doug 8x6 125 4/88 and 2 doug 8x6 125 3/100

1111, you are right about the quad, its a well built machine and blows away the competition. I was dissapointed with the top end but thanks to you, I found the answer to get around it. I will do the tire size in the future. He is only five so I am only looking for a little difference in speed. I will let you know in the future. I like the fact that you can bolt on a 80 motor and trans. What about the foot pegs and shifter lever? At least I know, I can swap engines instead of selling the machine and getting another one. That I like. The kid will be so use to the machine so the difference in hp, he will be able to handle with ease. Thanks again!

cool glad to hear it . yep the shifter for the 3 gear tranny what happens is you take off the palstic running gear thats on your sons 50 right and you get a set of nerf bars raptor80racing .com they got a nice set and away you go plus the guys down there tell me that the tranny will hook up to a 50 cc egine that should b cool to allright happy riding

I am not arguing that the 50 is a slug... And the reason is... Take a look at the CPSC guidelines for this class of machines. I beleive the maximum allowable speed is around 10 MPH. Now some manufacturers are following the guidelines closer than others. Soem of the chinese and Korean knockoffs don't give a damn other than the moment you place your dollars in their hands....

It is nice to know that there is a lot more speed and power left in both the 50 and 80 raptors.

For those of you that know me, you know I am quite outspoken when it comes to parental control, and responsible riding with regard to youth riding. So please understand that personally I am opposed to any modifications to machines for children under 6.. maybe even 8 years old depending on how they ride and OBEY your directions. It isn't a wquestion of holding on and twisting the throttle.. it is more a concern that youths this age do not exude a lot of good judgement, especially when put in an emergency situation. Therefor, this is the reason for my stance.

I sincerely hope that you watch them like a hawk, and consider using some wheel extenders to make the machine wider. The safety margin for rollover is greatly improved when doing so....

Good luck to you and great riding....

well siad dragginbutt the guys at raptor80racing .com really stress widing kits front and back when you start adding power ad ons it was the first thing i ordered widing kits 6 inches added up front and 4 inches added in the rear very simple and it defintly makes for a much more stable ride allright happy riding

Got the cdi box today from a guy off e-bay. What a difference that makes. Now it's a much faster quad. Hey, was it hard to open up the slider on the carb? Any pointers you can give me would be great. I think with these two mods, I will be a happy parent, not to mention the grin that is still on my kids face after he took it for a ride. Sweet!!!!!!

hey thats great glad to see you found a cdi box and that your kid had the grin sounds great. in terms of cutting the slide valve in the carb one go to rivamotorsports.com there you will find exploded drawings just so you have an idea any wasy it easy get the carb out and apart and you will see the slide is basicly to long so yo have to shorten it so take off the top of the carb were the throttle cable came in took the slide droped in then back it out until its flush in the carb chamber now you have a section of the slide valve sticking out of the top of carb were you took of the plate for the throttle cable mark it and then cut it right acrosss take the top right off. the metal is pretty hard dont put it in a vice you might crush it out of round i held and used a dremel tool stell cut off whell put it all back to gether and you will see a really big grin on your kids face hey another really easy and cheap up grade is a k and n filter and jet kit i think the jet is like 18 bucks for that ride and the filter like 20 to 30 bucks thats helps it out to you the truth of it is i went all the way and the first time my boy rode his quad he was blowout of the water how much more of every thing power tourqe handling of coures i did the widing kit and wheels to have fun be safe hit me up for any ideas like turning the gear shifter form a handle style to foot peg style or puting foot peg for the rear brake another great and cheap up grade any ways happy riding

Do not forget you also need to grind where the cable hook,s up under the thumb throttel cover.
