With u-j in hand, grab consecutive parts and wiggle them in all
opposite directions while watching the joint line between the crosses
and the caps for any play. You should not be able to see or feel any
play or roughness.

Then spin the carrier bearing while it is in place in the swingarm. If
no roughness, leave it in place but clean the inner race throughly with
a strong degreaser. Do the same to the u-j boss that inserts into the
carrier. Then glue them together with JB Weld Quick or red loctite so
they spin as one.

You can use a punch to "knurl" the parts for a better fit, but that
just makes it hard to re-assemble. The gluing gives a better fit and
assures ease of assembly.

This cleans off the clutch dust. The real problem is usually notches
in
the splines of the input hub or flywheel. This will cure the symptoms
for a time, but you'll still need to change the clutch to make it all
better. Changing the clutch on a loop is a fairly involved job, even
if
you leave the engine in the frame. And, most often, the u-joint or
carrier bearing will need attention, too, so budget for them.

Greg - (and others who have written on and off list with good advice) -

I assume that I will be able to feel or wiggle the U-joints and tell if
they need replacing; any roughness or stiffness or looseness would be a
sign, much like a car's u-joints?

I'm going to try the rinse-and-spin tomorrow; the only thing I wonder
is, if the problem is caused by clutch dust or notchy splines, how come
it's temperature-sensitive? The clutch behaves beautifully, nice and
smooth and even engagement, when it's cool or when it's only used
occasionally. It's only when I have to sit in a line of traffic with
the clutch in (can't leave it in neutral because I'm anticipating
taking
off any second) with the engine hot that it starts this monkey
business.

Well, enough talk I suppose, time to get the paint thinner out tomorrow
and report back.....

Thanks!
