My R65 is annoying and buzzy as hell on the highway. This leaves me to cruise at what I feel is a painfully slow 55mph. Without buying a new bike, how can I fix this gearing issue I am having? Well I came up with swapping out the rear drive (31:9) for something else.
I would like a 33:11 rear drive (3.00 ratio) but it seems they are all on R80s and R100s with disks and my bike has a rear drum. Can retrofit the drum in there or would I have to swap to disks?
Have you been through all the usual suspects? Timing, Valves, Carb sync??
