In case anyone is interested, here are some pics of my 1975 R90S Cafe' project. I bought it as a rolling basket case, but it has good bones and had not been overly cannibalized as many R90S are.

Here is what one looks like new and stock. My frame after is is stripped to get powder-coated Engine with correct heads and matching numbers. Dellorto "pumper" 38s were only ever used on the three years of R90S, here are the rebuilt ones with new gaskets, clamps, isolators, fuel pumps, Tomasselli velocity stacks and more. Wheels are unique for this project, they are DID rims laced onto the BMW hubs, rear is increased to 19", an old racer trick for these bikes said to handle better and give more clearance. New Avon tires are same size front and rear. Polishing nearly 40 year old aluminum gets tedious at best. I'm doing something with the body I've not seen done before. Usually these bikes get some form of rear tail made of fiberglass or aluminum. I decided to keep the R90S body work, but shorten it into a solo seat version. First the sub-frame. and then the seat cowl. If you look close you will see the welded splice on the seat cowl where I removed about 6 inches. Additionally, the tank has been relined inside. Finally, here are two bikes I did in the past, one a 1979 Triumph Bonneville Special and the other is the exact same bike I'm doing now. You learn what you like and want each time you do one of these projects, and this time I aim to get it perfect!
