I recently installed a dynojet kit on my foreman. here is the situation, cranks fine, idles fine, runs fine, until it gets in the upper rpm range, then its like it just runs out of breath. i installed this at the same time I put a hmf pipe on. low and mid range rpm the bike pulls hard as heck, but when it gets toward the top of rpm curve it begins to stall.
