He Gang, time to address some of these oil leaks.
This one is perplexing. I replaced this oil seal for the shifter shaft but it is still leaking. The one I replaced is in the transmission cover. Is there another seal internally that needs to be changed?

It's a pretty good trip and ends up on the exhaust cross over pipe. It seems to have a little slop so maybe there is a bushing that needs to be changed as well?

There are three of them. Two in the sprocket cover and one in the tranny cover. The ones in the sprocket coverm one faces out, the other faces in so grime won't get in there. They act as bushings.

Hmmmm. so for the shift shaft there should be two, one that goes on to the transmission cover and the other in the sprocket cover?
I see the one for the tranny cover #92049D but I don't see one for the sprocket cover.

Thanks Steve

92049 behind the sprocket cover and one in the front. They show 92049 B at the top for whatever reason.

My 750 also has seals in the sprocket cover. Realize though that they have nothing to do with keeping oil inside the engine. Rather, they allow you to keep some grease on the shaft where it passes through the cover. The cover acts as a support/bushing so you want to keep grease in there or shaft wear will occur.
