Thanks Tim, I'll try there first. Someone is selling individual shims on ebay too.
Got a little more work done today. The rear main seal was leaking, a new one is on the way. In hindsight I think the leak was due to my rising oil level issue, when I parked the bike, the oil level was at the top (probably above) the sight glass. When I pulled the clutch assembly off the output shaft, oil poured out of there. I don't think that seal is supposed to hold oil back at rest, it will migrate through eventually. Still, no way to know for sure, so a new one will go in once it arrives. I spent some time cleaning the grunge off the inside of the bellhousing, I'm running out of stuff to do while waiting for parts, why not! I also made some guide pins to reinstall the transmission, dead easy, hacked the heads off a couple of bolts and slotted them for a screwdriver.
To install the new seal to the correct depth (not flush like the original), I'm going to try cutting a circle spacer out of an old yogurt tub lid. I should be able to use the old seal as a template and just tape it up to the back of the crankcases to act as a stop. Looks like it is about the right thickness.
Another task for today was installing a battery cable kit from Euro Motoelectrics. When I bought the bike, the battery was three years old and I had a big trip coming up, so I replaced it because it seemed to crank pretty slow. The new battery was not much better. Looking at the wiring, especially the pitiful ground wire, they looked like they would be hard pressed to run a turn signal, let alone a starter. The EME kit looks like it would have no trouble powering a welder! The new cables were a little fiddly to get through the rubber grommet into the electronics box, but otherwise easy to install. You just run them parallel to the existing cables, and throw away the old grounding cable. Can't wait to see how she cranks now!
Man, this bike is in good shape.
Got my valve adjusting tools ($28) and clutch pilot tool ($18.50) in the mail from Kenneth Lively a few weeks ago. They are really well made and a real bargain for the price. If you need a set, Ken's email is polepenhollow@yahoo.com.
Got my injectors and rail reinstalled too. The blue o-rings go toward the fuel rail, brown toward the cylinder head. Mr. Injector cleaned these for me and they came back looking like new.
