Vintage BMW Motorcycle Owners

Absolutely! This is good timing. I finally retired and we just moved to Canyon Lake from Houston and I am working on getting my bikes out of storage and back on the road. We are renting until our new house is finished, so I am still short on garage space. I got the R90S fired up last week and I need...

I have always assumed the initial elimination of the seat stay from the plunger frames was driven by weight reduction. There is no other logical reason I can think of. I remember reading somewhere that the f...

I should have said I don't use a lead additive. I do use Stabil, a fuel stabilizer, to help storage life. In the past, I also experimented with adding 2 stroke oil (about 100/1) with no discernible difference. My R12 and R6 run on low octane (87 USA) pump gas and seem happy. These are very low compr...

If my information is correct, the Europeans did not use tetra ethyl lead until after WW2 because of its toxicity. Alcohol was the initial octane enhancer.
