Ian,

How about the springs? Did you replace them? When you realigned the
flywheel did you clean the splines on it? I've noticed if they are
gummed up, the plates will not move freely.

Hey All,

Well....after 200 miles, and what I thought was a good fix to my grabby
clutch woes on the White Eldo, the problem is reappearing. The good news
is
that I now have some experience with the progression of this problem and
can
come to some concrete answers. Let me know if you folks agree with my
hypothesis.

When I first bought the bike the clutch was VERY grabby...almost
unrideable.
As I would ease out the cluth, trying to feel for the plates to make
contact, nothing would happen and then all of a sudden it would grab and
lurch forward (hey...maybe the bikes new name :-)). This problem was
less
evident when the engine was cold. The bike operated fine once rolling.

I pulled the engine but there were no noticable indicators of something
wrong. The splines of all components looked good....the clutch plates
had
lots of thickness. There was a fair bit of clutch dust in there but
nothing
gummy. I replaced the clutch plates....realigned the flywheel (it was
off),
lubed the splines and bolted everything together.

When I first ran the bike everything was nice and smooth. Clutch plates
engage evenly and the bike worked like a dream....until 20 miles ago.
After
spending a good day with my buddy Ed....riding about 80 miles the
grabbiness
is reappearing...getting progressively worse. I can feel the uneveness
of
the plates making contact as I engage the clutch. The grabbing appears
to be
consistent with engine rotation.

The clutch operates smoothly so I don't think there is any binding in
the
cables. If the problem was with the tranny I think it would have been
evident as soon as I ran the bike after the apparent fix. I don't think
the
problem is in the splines of the tranny hub. I replaced the clutch
plates
but not the intermediate plate.....

My thinking is a warping intermediate plate as it gets hot. I have yet
to
retest the bike when cold but will do that sometime today.

Any thoughts?

...Ian
