My friend here who is also ex BMW said the same thing about replacing as a service item but he was referring to the pivot bearings on the later self destructing types rather than the K mono lever or Paralever ones. However just changing the big bearing is not so difficult as one might believe if you are doing them all the time. My mate can set a bolt to a required torque setting and then check it with a torque wrench to find its exact, just like a musician of experience can produce a perfect C. Doing that big bearing seems to be a wise move and after what I saw I think I would pull it at a defined mileage as it doesn't take much to do it.
Rather strangely my K had a strange incident August last year which was about 8k miles before the bearing went. The final drive oil started pissing out of it and it ran hot. So I changed the oil, did it again for a few days, changed the oil a second time and the problem disappeared and it went back to running at normal temperatures. No idea what happened or why. However I did keep an eye on it and then started to feel a barely perceptible change in the drive.
The early 16 tooth RS drive is like hens teeth and if you have one of those worth swapping the bearing if the drive is good.
