ok i race my buddies 2000 wolvrine in harescrambles races. i was wondering what would help out the performance more after we done this to it......wiesco flat top piston and rings and a cobra pipe. it runs good now but need more power. what else can we put on there?

 

A Wiseco high compression piston and rings will help you out on top end. The Cobra Pipe will help the entire powerband. Did you put in the stock replacement piston or did you go with the higher compression piston? If so how high did you go. Depending on how much money you are willing to spend, the parts wil differ. Let me know how much money we are looking at and I can tell you more about what you should get. Racing gets expensive. I would definally re-jet the carburetor since you have the pipe on it if you havent already done so. The easiest way to go about doing this is to buy a K&N Jet kit. It will tell you what jet will work with what you have done.
