i've got unhealthy slack between acceleration and engine braking, and it's in my final drive. the K100RS had the lowest gear ratio, thus a higher wheel speed per engine RPM, and i want to keep this bike stock. so while 32/11 (2.91) final drives are pretty common, i really want a 31/11 (2.82). i'm not ready to learn how to tear one of these down and source new gears for it, so i'm hoping that someone here has one they're willing to sell. any monolever will fit, it doesn't have to be from 1985 like the rest of my K100RS. greg hutchinson (of airheadadventure.com and the undealership in redwood city california) is also calling around trying to find this for me, in case you hear the same request from that other pathway.
PM preferred.
