Hi Les,
When you go to all the work of pulling the engine and transmission out,
I would certainly replace all of the seals:
Rear main seal
Front main seal (although you certainly don't need to pull the engine to
get to it)
Clutch input shaft seal
Clutch output shaft seal
Pushrod shaft seals
Various o-rings and gaskets - as needed
It has been my experience that if you don't replace them all, the ones
you don't will start leaking on you. I would also install a new rubber
boot over the UJoint if yours looks even mildly worn.
As for clutch bits, you'll probably have to wait and see what you are up
against once you pull everything apart. If you have lot's of wear left
in the clutch plates, you may want to degrease them and reuse them
(opinions will vary on this, I'm sure, but I've had good luck with
this). The springs are so cheap that you might as well replace them.
Also take a look at the splines on the clutch hub to make sure they are
in good shape.
I'd just give it a good once over while you're in there. Good luck!

Hi all, Sorry I haven't been around to enjoy the posts for quite a while; my business went ballistic on me this summer and I'm just now (sort of) getting under control and able to follow the group again. I've hardly ridden the Ambo since I got it in April :-( Anyway, I did ride it a couple of times and when I parked it I would come out later to find a pretty good splotch of oil under the engine area; it seems mostly to be toward the rear and maybe even at the rear of the tranny. I should also add that the clutch will slip under heavy load (acceleration). In reading Guzziology and talking to Moto International on the phone it sounds like things are pointing to the pushrod leaking. I was told it a common malady. I was also told it is an expensive one; 6 to 7 hours labor (@$75/hr) plus parts...ouch! Even though I don't have a lot of time available I'm pretty well resigned to doing the work myself as I can't really afford to just drop it off and say "fix it". But before I get myself that deep in a project (I'm told the engine has to come out) I want to mine the knowledge of the group here. Is this common enough that it's the most likely situation? And...if I need to do this what other things should I plan on doing while I've got good access to other areas? Thanks for ideas, comments, caveats, etc! Les |
