[usuckaaa]

hi, i'm noob, so i don't know much about pocket bike. i got a 47cc. it ran about 36mph. but i want it to faster, but i don know which mod to buy to make it faster. plz show me some good carb, good filter, good pipe or any thing that can increase the speed of my bike. thx, by the way, is R1 Racing Carburetor good? :)

You could buy a ada wyk or wt carb and ada air filter. For pipes if you have a round bar between the rear tire and air filter then you can't put in a sikk pipe but ada has a few good pipes and jetpro has a nice pipe. You could also add race piston, ported cylinder. head kit, roket key, etc it all depends on how much you want to spend.

I agree till the race piston part. No need for a race piston for extra RPMs if you dont need it. Yes you can have a high revving engine, but do you have it ported right to get the power or is the timing all off. A rocket key isn't worth it because it kills top end and makes your engine run hotter. NOT GOOD :nono You need to mess with different gear ratios. Get a bigger sprocket for low end and switch to a 8 or 9 pinion to counter it. Get a pipe from pipelyne in san jose, ca or even try if jetpro might make one. Try things one at a time so you know what works and what doesnt. Slapping everything on at once will leave you dumbfounded on what is causing problems.

hi, thx for the reply. but i have a question. i thought if u use 8 or 9 pinion, u will have slower top end. i heard one of the guy say to use 7 for 47cc. he say it best. and use 68 or 72 sprocket to increase torque or top end. is it true?

[needforspeed]

think of it this way. on a bike the bigger front gear and the small back gear the more push it will take to get it started but once it does it will reach a higher speed than a smaller front and larger back. By using the 7 8 or 9 pinion you will gain top speed but loses some speed and acceleration of the line. If you add a smaller rear you will also gain top speed but lose some acceleration. therefore adding a 5 pinion you will get more acceleration but about a 10% decrease in top speed. same if you add a bigger to the back
Hope This Helps
