i just bought a new complete big gun race for my crf 230, and i was wondering what jettings i need to change, if i need to at all. im kind of in a hurry since my family is goin up to hungery valley in a few days. any advice would be greatly appreciated.
thanks for your help, Mike


p.s, ive ridden it with it installed, and when i let off the throttle, it pops (backfires)? like when you take the baffle out. i already took oput the snorkel as suggested.
