OK, I finished getting everything back together today. I ended up replacing the clutch carrier, spring, both pressure plates, and of course the clutch disk itself. Also new air filter and rear brake shoes. My new rear tire was not in Thursday when I stopped by so I'll stop and have it installed this week some time.
I made a tool to hold the fly wheel in place for removing and reinstalling the bolts out of plumber's tape. I enlarged two of the holes. One went over the upper right tranny/airbox mount stud; the other went over one of the old clutch bolts which I screwed back in for this purpose. It worked perfectly.
After adjusting my clutch rear lever, I still end up with more free play than I had before, but it's not hard to shift. The clutch doesn't disengage until I've pulled the lever back about an inch. I seem to remember reading something about this before, when somebody else upgraded all the clutch parts except the throw out bearing assembly, but I can't remember what the fix was. I'll look for it. The perceived hand effort is quite a bit lighter than it was before, I don't know why. It works for now, and I'll probably ride the bike to work a couple of days this week to make sure it's OK for the trip to Chief Joseph this coming Friday.
Mmm, sleepy now. G'night!
