hi guys just an update got my self a VMR118 "4 coil"with new cdi, and light weight flywheel and light weight oil spinner throttle is relli responsive also fitted a high compression piston i do recomed as i got told the other inner router kit i posted was not worth it as it would unbalance the crank and would just rev harder and get there quick and wouldnt gain much cheers
