Come on now, I'm just trying to get a crude little motor to run as smooth as possible.The one in question will do about 48mph. Thanks to Arrow Motor Bikes ported cylinder. rechambered head and expansion chamber. The Delorta SHA 15/15 didn't add any speed but it does run a lot smoother at top end. It's the bottom end that was giving me trouble. I went up a few teeth on the rear sproket, increased the idle rpm and it doesn't buck until I get below 15mph and that's all I wanted.
