It's been a while since I pulled a yoke out of a Syncro driveshaft, but I
have a distinct memory of the bushing being made of brass.  In the images I saw
of the SA bushing it appeared to be plastic.  If that is the case, installing
one is about as cool as buying a bike with plastic swingarm bushings.

A good smear of grease on the shaft of the yoke whenever it inserted into the
driveshaft will help dampen a clanging center driveshaft.  As pedestrian as
it is, it is still amazing what a little dab of the right grease in the right
place can do for a mechanism or an insertion.
