I like the mid to hi rev 310 kit, or 330. no mention of jet change, or recomended pipe, or air flow..

spend the extra and get the 330. Recommended pipe is the ATC-5


As for a carb you would want to run atleast a 38 PWK AirStryker, most likely a 39 PWK.

a lot depends on the type of riding you do. each kit has differant charecteristics.
