Loud shifting, any ideas?
Hello, I inherited a 1971 R60/5 BMW from my dad. I was not an avid bike rider, but I commited myself to get my license and ride my dad's old bike to keep his memory alive and to pass it down through the family. I am enjoying 20-30 mile rides now and then. I cleaned up the bike that hasnt been ridden in 8 years and have been riding it for a few months now. It only has 30k on it and runs great, except for the shifting. When I shift gears the bike seems to "CLUNK" into gear most of the time. Is there some kind of transmission lubricant I should be using or is this normal in old bikes? I would appreciate any suggestions.
