Sam,
I removed the rear wheel and swing arm and I think I will be able to get to
the output shaft seal with the engine and tranny in place.
I'll let you know how I make out.
Regards...Ian

Most likely the output shaft seal leaking. Unless you have short shocks
or carry extremely heavy loads, it's unlikely rear drive lube is finding
it's way that far forward.

I'd mark the position of the shift lever on the back of the tranny in
relation to the shift shaft and the shaft to the housing as well. It's
probably best NOT to disturb the ecentric pin (slotted head, secured by
locknut) on the cover. Keep the shift shaft in position and slide the cover
off of it.

There's no seal on any I have that are disassembled. Someone on the list
added one by making a fixture to hold the cover and cutting an o-ring
groove. Cheers,
Charlie
