After talking with Rick at MG Cycle I am thinking that the problem could
have been with lubrication. He was also saying that he has seen grabbing
clutches in the 4mm splines before. I'll be replacing the clutch plates with
new ones I had laying about. I'll clean everything up really well....lube
with moly and see how she is.

Of course I will let you all know of the results...Ian

Ian:
I vaguely remember a discussion in Guzziology, I think, concerning
the transmission housing and the engine on some of the loops being out
of alignment, which may help the clutch hang up. No idea about what
you'd do about this. I'd get a magnifying glass and very carefully
inspect the input hub and flywheel teeth looking for clues.
Something makes the clutch plates hang and suddenly engage; how
about input hub and flywheel teeth (tooth) lubrication; a little spline
lube might be helpful here. You might go for another set of springs, if
you have access to have them tested.
Are there some clutch friction discs that are grabbier than others,
like brakes? I'm sure you'll let us know what you find out.

 I recently bought an Eldo which had a grabby (very grabby when
 warm) clutch in first gear. Many of you put your 2 pennies in
hoping to get that coveted prize (bragging rights).

The general concensus was that the problem would be the tranny
input hub. My thought was a warped intermediate plate. Maybe
springs that had different spring forces? Bad clutch plates?

OK....Ed and I pulled the engine this morn and pulled the tranny.
Input hub...perfect with no discernable wear. Clutch plates
looked new and the teeth were good. Intermediate plate looked
fine as did all the other bits and pieces in there. The only
thing was that there appeared to be quite a bit of brownish dust
in there which I figure must be from the clutch plates. The push
rod was straight and looked well lubed.

Any thoughts or suggestions? Any way I sort this out without
having to reassemble the engine and give it a go?
