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.
