tuned 136 malossi (approx 40% transfer port enlargement) with zirrisilent pipe and , zirri short 4th gearbox .
will a 2.34 pull well enough using the zirri short 4th ?
0r is a 2.56 more advisable. This scoot does some fair distances and while I want to reach the necessary resonance rpm to hit the powerbands i don’t want it screaming it tits off whilst burning p2’s off.
gearing calculator shows 77 mph at 8k rpm using standard box and 69mph at 8k rpm using zirri short 4th.
