I’ve collected information that should help someone who is interested in doing rebuilds on older BMW motorcycles. The material is organized by each particular project.
Links to write-ups about the work I’ve done on all these bikes should be visible on the left side of any write-up page in the navigation bar, as is the case with this page. And, toward the end of each of the rebuild summary pages below is a list of write-up pages organized by parts fiche major heading–for example “11” is engine, “13” is fuel preparation, etc. There is also a link to a rebuild resource list to help you locate parts and advice and services, and a link to documentation about the airhead electrical system that is a work in progress. Happy rebuilding.
My first project was my original owner, 1975 R75/6 with 103,000 miles that I built into a R75/S replica of the famous R90/R100 S models. The next one was a two-owner, 1973 BMW R75/5 with 97,500 miles. I always wanted an R100RS and found a 1983 bike with 83,000 miles that needed a lot of TLC. I got it running reliably and then I got side tracked. I found a first year 1977 R100RS with less than 35,000 miles. So I switched my attention to the 1977 R100RS in hope of completing the rebuild/restore in time to attend a 40th anniversary celebration of the release of this historic motorcycle in September 2017. I did complete that rebuild in time to ride to the celebration in Pennsylvania and back, and then completed the 1983 R100RS build converting it into an RT model.
My current project is a charity rebuild of a 1983 R80ST. I will auction this bike and donate all the proceeds to the Motorcycle Relief Project, which sponsors motorcycle rides with therapy for military and first responders suffering from PTSD.
