"Sophia's" ('72 Ambo) rear drive had no cutouts or flat spots. Found
that rather odd. Were cutouts in the swingarm though.

I personally wouldn't use a split type boot except in an emergency. The
stock boot seals much better in my experience. Cheers,

It should have the little cutouts in the pinion carrier for venting and
oil return. The swingarm boss has them, too. Match the cutouts on the
carrier with the cutouts on the swingarm.

Have you considered that the output-shaft seal on the tranny is
leaking? If not, consider it. Check fluid level in the tranny.

 Checked the compression this morn. 151 psi left, 159 psi right. Was a
pleasannt surprise as I expected the left side be be lower. I feel
much
better now knowing the compression is in a good range. Will see how
she
runs once I replace the distributor springs.

Will head out to the garage and start disassembly of the rear drive to
check if it is installed correctly. Spoke with Mark E this morn and
the
Ambo pinion may not have the flat spots on it as described in
Guzziology. Thanx to Paul Linn for the pix, I now know what to look
for, but in the few rear drives Mark checked in his shop, none of them
had the flat spots on the pinion nor on the rear drive assy, so I may
be
checking for nothing. Will replace the gaskets though when
reassembling. Gotta figure out why my Ambo is heavily migrating gear
oil to the driveshaft boot then pissing out all over the muffler and
tire.
