How to follow the new emission standards on BMW motorcycles on the 1979 models. Another example of the dealership’s work to keep the factory technical manual up to date. As a BMW dealer, I can remember that we got 1-2 of these a month to put into our Repair Manual. The repair manual was in a standard European 4 ring binder. We removed the “old pages” and inserted the new ones. No matter what Repair Manual you could buy, it was never current.
