Hi so i sold my blaster a few weeks back but guy brought it back after saying the powerband wasnt working. so i found a air leak. fix it with a genuine yamaha gasket(metal type) and its sealed tight. but my powerband still isn't engaging. its like a 4 stroke its throttle no problem and not dying out but just won't lift or doesn't even feel like there is anything there. just don't understand it as i just done a top end on it with a new wiseco piston and rings and gaskets.
thanks
thanks
