I started my next rebuild project, a 1983 R100RS and am posting the work on my blog here:

I posted the project inspection write-up a few months ago.

You know, being retired just seems to leave no time to work in the shop. I end up doing all sorts of things and the next thing you know, time for bed. Anyway, I finally wrote up the Bing carburetor rebuild/refinish work I did on the 1983 R100RS project.

When I rebuilt a 1973 BMW R75/5, I covered the procedure to rebuild the Bing type 64 carburetors, which are 32 mm, and the Karcoma petcocks. The R100RS has type 94 carburetors that are 40 mm and the Karcoma petcock outlet is 90 degrees from the inlet instead of directly underneath the inlet as for the R75/5. After 10 years, the designs are essentially the same, but there are some differences which I cover in the procedure write-up.

Here is the link to the R100RS Bing type 94 rebuild/refinish procedures.

I hope this material makes it straight forward for folks to rebuild these carburetors who may have been afraid to tackle a carburetor rebuild. Here are some before and after pictures of the carburetors.
