This bike is my first BMW that I bought new in 1975. It’s the first bike I rebuilt. After I put over 100,000 miles on it, I gave it to my son, Branden. In about six years he added another 100,000+ miles on it. So it’s time for a top-end refresh. He decided to install a Siebenrock 1000cc upgrade kit that we got from Euro MotoElectrics.
Here is video of how Branden did the work.
