    my original motor was a '77 but it also works on a '80.

    I run a JT Sprockets JTF512 front sprocket with a 6mm Front Sprocket Spacer Washer.

    I have a completely custom rear hub so can't comment on that.

        What gearing are you running?

          it depends on the track and the weight of my passenger. Tight short tracks I run a 16T front and anywhere from a 40-42 rear. Long tracks I run 15/46.

          keep in mind I have a 13" x 8" racing slick on the rear.

              one of the other inmates here needs to answer that. I would start with OEM personally.
