Found the bike of my dreams- an R90S, 1976. It is a barn find that has been stored for 20 years. Unfortunately there was no ignition key, but I couldn't begin to get it going since the tank is filled with crud. However, the engine wasn't seized which is encouraging. Front brake on right size was frozen, brake fluid leaked down onto wheel rim. Master cylinder is a mess- lots of corrosion.Aside from the brake problem, the bike is in very good shape overall. It was stored under a cover. I know it's a long shot, but does BMW maintain a database for keys so that I can order a replacement, or do i have to remove the lockset and have new keys made? Also, does the same key work in the fork lock and seat lock? Many thanks!
