Last night I finally found what was the final straw. I was wondering
where the oil got blocked. And why it only starved the rear crank
bearing when everything else is untouched? Last night, after grinding
the reflectors loose on my spare fender, I looked it over again. I was
lookng for a blocked oil line somewhere. I took the fore-aft oil line
off the bottom of the motor. This line goes from the oil pump and feeds
the crank bearing and the cam bearing in the back. But there is also a
pressure switch at the aft end of the pipe. It is a spring and plunger
affair. I took that apart and the plunger was scored and had at least
one fair sized chunk attached to it. SO. My assumption is that the
plunger was jammed in a position where not enough oil was making it to
the crank bearing and so it seized up.
That may have been it, but did you check the sludge trap in the crank?
