Thanks MIXR. That's kind of what I wanted to hear!
I am now also reading the enormous thread on VW clutch in an r1100. I don't expect to improvise that much, but I am wondering if
1. I can get away with just a new clutch disk (maybe even a ceramic one or whatever fancy/better is here),
2. I should buy the whole clutch system, USED to match my used trans (clutch on fleabay from a 2000 rt)
3. I should go to the dealer and trade my firstborn (or some extra organs) for a brand new "clutch kit for 1997 r1100gs" with pressure plate, disk screws, and wherever else it includes.
