Hey Gunnar,
I just thought of something to check on your Guzzi resto.
do you still have the big end bearing shells? If you do, look to see if
there are little bright flacks of metal in the duller looking babbitt. My
original chrome bores flaked and put alot of tiny chrome flakes into the oil
system. Maybe post some close-ups of the shells on your site.
My big ends were in bad shape, but the crank was still OK. The sludge trap
was almost full (if you didn't know, this is located on the rear of the
crank, the crank must be removed to service) If this is full, you might have
issues with oil distribution.
Have you checked the rocker spindles to see if the oil passages were
clogged? Mine were partially clogged with the same particles and some
galling was seen on the spindle and bushings.
I read that you wouldn't be pulling the crank, and just thought to warn that
if you got the bike without knowing the exact mileage or service record,
checking these things would be a good idea
