well maybe post more info on your bike and you could check out http://www.dynojet.com/

 

You don't need a "jet kit" alot of times when you buy a pipe it will come with some info as to what size jet to run, but with a 2 stroke it's harder to say exactly what jet you need. You pretty much need to go buy some jets and ride it for a short time, look at the plug and base it off that. White would mean your too lean, black or fouled would mean to rich, a brownish color indicates your correct. Also try looking at a dirtbike site not an ATV site for help with a starting point.
