Last night I tuned my buddies raptor that has a pro flow intake, and a DMC Alien exhaust. Well we went out and rode today. When we went to race I was expecting to beat him by about 4 bike lengths. Wow I was relly wrong. from a dead stop we were even off of the line, because of my wheelie problem, then once I shifted in to third we were side by side, and then when my front tires dropped. My bike pulled those 4 bike lengths before the end of third. Then I shifed into second pulled probably another 5 bike lengths, and when I shifted to fifth there was no looking back it just pulled alot further away and really fast. I didn't realize how quick my bike was until I raced him. so far his was the fastet bike I have raced so far. I love my new motor.

 

that sounds pretty fast if only my bike was even close to that fast

whats the point of the oversize valves what does it do?

 

They let more air and fuel into the combustion chamber.

 

did u spray?

 

No I can usually only spray in fourth and fifth because i have a stock swing arm. And by fourth I didn't need to spray.

 

you should increase the size of the countershaft sprocet. It will increase the amount of wheel spin, causing your bike to not wheelie. I flipped my banshee over a couple of times before i figured this out.
