So I have a 1980 R100RS completely apart. The 5-speed transmission, final drive andrear wheel have been rebuilt by Kansas City BMW. The engine probably needs some top end work (mostly clean-up). the frame and subframe have been powder coated. All parts are in my garage, some need rebuilding-forks brakes, etc. an interested party looking for a project bike ask me to name a price. All the rebuilt parts have zero miles on them. Any suggestions?
