Jim, regarding your clutch, replacing it when the IMS / RMS is exposed really makes economic sense. The clutch plates may well be only 50% worn, but that's only one part of the clutch assembly - you still have to think about the release bearing wear and fingers breaking. If you change it out now, there is also a very good chance that your flywheel is still servicable too - which saves another $1,000 in replacement costs
Only a month ago I had the LN bearing and new RMS replaced with a new clutch kit. The clutch was original with 47,000 miles on it and the linings were +/- 50% worn. But the release bearing was shot - loose and rattly.
The new clutch action is far superior in feel and takeup - and the best thing is that I don't have to worry about any of it for the next 50,000 miles
