It never pulled in 6, only when it was stock it pulled in 6. But I have a friend with a stock banshee (jus fmf pipes) i blow his doors off. My 5th gear blows right past his 6th. It started when I did all porting and bolt on parts but man I tell ya what 1-5 is wow compared to stock but no 6 acceleration. Did I just use a too small back sprocket? Ct said drop a tooth or 2 but maybe I shouldn't have or maybe they said go up a tooth. They won't tell me at this time if its up or down, they say send us the motor.
