Was wondering what gearing should i use for my bike i have a 125cc gpx race engine, high comp piston, race cams, whopping power, 13,000 rpms stock motor. What gearing should i use since i ride at frankston mx track which is full of turns and corners which is sort of a tight track, ive got a 13tooth front and 41 tooth rear atm, also i have a 26 OKO carbi with factory jetting was wondering what jets should i buy to give it some more performance??
