these desktop dynos make me crazy. ok... try changing from your 64 cc double humps with 1.94's to a vorteck 1.94
with 64 cc's. probobly a 30 hp diffrence. but the desktop
cant tell you that. theres too many variables. i had a customer tell me that if he advances his cam 2 degrees he'll pick up 80 hp cuz the desktop dyno told him so.
