Monte, maybe you could point out any differences in the procedure between the R65 and it's larger cousins... The sealed ball bearing assemblies in my monoshocker are looking better all the time! 
My experience is with the R65 only. Dun no nuttin' bout nuttin else.
Someone somewhere made a statement that has stuck with me; it went kinda, "There's this whole BMW angst about setting the bearing preload." Thought it was funny then and now, too.

http://bmwmotorcycletech.info/ has some extensive and quite wordy thoughts on the BMW's rear wheel bearing preload setup. Plus, I recall a link to an other technique that is far less involved. And then there's my own technique - similar in ways to the BMW and the tapered bearing preload set on my Cabriolet rear axles.
I do know that I will in no way never ever use a carwash high pressure water stream to wash my scooter. That's how the PO cratered the rear bearings.
Research the Snowbum articles. You may glean some knowledge or discover a new cure for insomnia.
