Hi Ted,
Haven't found it necessary to replace the piston pin bushing in the rod
on any I've done a top-end rebuild on. Always a good idea to check the
fit though, then decide on an individual basis.

Tom I had same problem twice this year. First time was broken top
compression ring. Then the other side had pits in the cylinder wall from
sitting for 4 years. Oil comming out breather and next time oil burning
under load or long idle. Anyone know if you replace rod top bushing when
installing a new top end??

- need a second opinion. After cleaning and ensuring the flapper valve
on the breather box ('74 disk Eldo) is working, I'm still getting oil
from the breather box tube. The frame crossbars back of the
breather tube are wet, and it always leaves a few drops of oil on the
floor where I park it after riding. There is no ball check valve. There
is no "blue smoke" in the exhaust, but the right side plug is a bit
oily, so I'm assuming its probably just worn rings. Its using some oil
- enough for me to determine on the dipstick after 150 miles or so - but
I'm not sure exactly how much. If I've got to tear down the top end, I
might as well take the opportunity to put in a Nikasil kit.Its not
showing any other symptoms, no leaking, no running issues, idles fine,
etc. Is it safe to ride it through summer without risking more damage,
or should I do the Nikasils now? I'm leaning toward's doing them now,
since it really isn't that big a job on a old Guzzi (at least it doesn't
appear to be for the unindoctrinated).Thanks, -tomYour
