what is best gear ratio for dragraicng with turbo gixxer.since they have really tall first gear.i have stock gearing.i dont know if i should change the rear sprocker or the front.i launch it at 7500 rpm and i think thats way to high.i also live at milehigh,colorado,elevation is around 6000 ft.i made 250 hp at dyno,and thats at sea level so i should make around 195 hp or so.
