I recently put on a supertrapp exhaust on my 00 warrior along with a k&n power kit. i installed the stage two kit with whatever number jet in it(i forget what number it was). the quad runs great except for top gear, which if i run it at more than half throttle in 6th it sputters. i've played around with the discs in the supertrapp and it does it with all combinations. should i try a hotter plug or does it have something to do with the jetting?
