Hey All,

Well I am getting into detective work on the White Eldo with the grabby
clutch. Here is what I found so far.

Pulled the engine and discovered that the seal was leaking. Replaced the
single lip seal that was in there with a double lip type. The gasket for the
oil breather was leaking. I discovered that one of the bolts was stripped. I
fixed that with a longer bolt...there was enough thread to get a good
bite...loctited it in place.

Here is the kicker. When I pulled the flywheel I marked the crank and the
flywheel as to rememeber the orientation. When reinstalling this morning
(another story in itself) I noticed that if the engine was at TDC on the
left cylinder (timing mark lined up on the pulley and mark on the flywheel
lined up with corresponding mark on case) the marks I had originally made
did not line up. If I rotated the flywheel one bolt to the left then the
marks would line up. Am I missing anything here or did the shop who worked
on the engine miss lining up the crank/flywheel?

Since the bike ran 400 miles home I am assuming that the cam and crank are
aligned ok. My question is whether the fact that the flywheel being
misaligned could cause the grabby clutch? What is the purpose for the
flywheel needing to be aligned in that orientation in the first place? I am
thinking balance.

I am thinking I need to ensure engine at TDC on the left cylinder....and
then align the flywheel. I was noticing that the distributor lobe was at its
correct location too....that having just opened on the short lobe.

Oh....one last thing. The other part of the story is that originally what
allowed me to discover this anomaly was that I installed new flywheel bolts.
Stupidly I bought cheapass 8.8 bolts and in the process of torqueing them
down to 30 ft pounds they started to strain. One even broke! Lesson learned
here folks. Get 10.9 bolts in there.

When I bought the bike I was told by the PO that this bike had been worked
on by a particular Guzzi shop. To be honest that was the only thing that
concerned me. I don't know about you folks but when I put my engines
together I ensure that I don't leave stripped out bolts in the bike. Any
bike I have worked on doesn't leak after 3000 miles. No one is perfect,
parts will fail and mistakes have happened but I have seen this too often
with this particular shop. My outspoken opiniated manner wants to yell out
the name but I know that is inappropriate on this list. However I will let
people know my thoughts if they contact me off list. I'll also give my
positive plugs too. There are some awesome guys out there that do great
work.

OK...I have vented and will get off the box. You folks are the best.

...Ian
