Avon gearing

You might want to mention what tire diameter your running.  Is it a dry clutch and a box muffler?

12" tire diameter, Max-Torque 2 shoe dry clutch, box muffler.

The 12 inch tire is a very large diameter which would require a larger bottom gear.  Also the 2 shoe max torque clutch has a very low engagement which hurts the bottom end power.  Not sure what size tires the others who made recommendations are using, but most likely they are smaller.
