Personal experience, 82 R100RT, mileage at approx 40K miles. Valves needed adjustment every 600 miles. Pulled heads to rebuild and discovered that the seats were perfect but the valves were toast, almost ready to pull through the seat they were so thin and curled. Sorry it was a long time ago so have no pictures. The valves were poor quality metal and so was the final drive spline. This is apparently a known issue with this vintage of Beemers.
