R80 RT 1982 - final drive problem?
Just trying to decide what things to try and fix this summer. One problem I've noticed is that at around 2-2.5 revs very small movements of the throttle often result in a nasty shlunk and thump from the rear section of the bike and an associated lurch forward as a consequence. I assume this is not meant to happen on the R80!
Is this likely to be a problem with the splines of the final drive? What other things should I look into to begin diagnosing this problem.
