The clutch has performed flawlessly ever since I reinstalled the wave-washer and associated fiber plate.  No squealing, grabbiness, etc.  It handles the power with no indication of slipping.  Operation is smooth with no drag.  Neutral is always easy to find.  I expected all the clutch components would be in good condition.  But when I went to remove the hub, the nut was loose.  I knew something was up.  

The thrust washers had the same wear both Dave and I have encountered.  Granted this was a very long test, but I would prefer that things stay tight.  I probably should have been on a routine tightening regimen.  I almost always remove the clutch cover when I do a service, so it would be a simple task to tighten the clutch hub nut.

The thrust washers were worn.  I will have to replace them.  This is the inner washer that resides up against the input shaft ball bearing.

The sleeve that runs in the bronze bushing was in great condition.  No bronze deposits on the sleeve, so I am pretty sure that the grabby squealy problem is related to the basket binding on the sleeve.  The wave washer has fixed that.

You can see the insert separation from this side too.  No easy fix for this, just gotta run it till it gives up.

This is the exhaust lobe.  It’s just a bit worse than the intake, but still in pretty good condition as far as I’m concerned.

The right-hand exhaust valve adjuster screw had some pitting on the tip.

Throughout the test of the oil system, the valves never needed to be adjusted to correct a loose condition.  If adjustment was needed, it was due to insufficient clearance.  That indicates that there is almost no wear taking place on the cam lobes, cam followers, adjustment screws, or valve stem tips.

This is a shot of the adjustment screws for the intake valves.

There are narrow polished circumferential bands on the center cam bearing and right-hand steady bearing.  It appears there is some edge loading taking place.  I’m not sure why, but it doesn’t seem to be causing any significant distress.
