Yeah. Go to BMWSportTouring.com and search on "clutch spline". Here's 
one discussion:

The clutch spline failures seem to be at high mileage (80~100K), 
although they're so rare it's hard to see a pattern. Given the amount of 
work needed to get to the clutch splines on an Oilhead, my personal 
cost-benefit analysis says don't worry about it. (As it happens, the 
tranny was off my bike at 60K and 80K and the splines were fine).
