[RICK LAKE]

Hi Dean Without chokes in the webers you should be able to turn 7800 with a small motor. If you want more a set of 52-58 mm TWM will take you to about 9,500 rpm, about the same time the bottom end comes out the bottom. Change the gear ratio first. It's got to be cheaper in the long run. I will call Rick L I will talk to you about cams latter
