It's actually in the pics in the first post - that shaft end that is the lower right section with the retaining clip on, is the selector fork shaft.
There is an o-ring about 1/2" into the case.
You can actually withdraw the shaft far enough to replace the o-ring (being EXTREMELY careful not to pull it out TOO far!)
Similarly, when putting it back in, you have to be even more
careful of pushing it in too far - see my note in the post above about holding the end of the shaft with vize grips so it doesn't 'get away from you'.
However, if you can successfully seal the bolt-hole you suspect is the problem, then it may well be
that screw-hole - in my case the oil migrated to the hole slightly above the selector shaft, but not as far as the next hole up from where you think its originating for your
This is actually a 97-01 Transmission Gear-Change Case - but essentially the same regarding the shift drum and selector forks on my 02-04 series engine and also the 1050 motor.
The upper shaft carrying the selector forks that is almost directly in the middle of the pic is the one that had the leaking o-ring seal (that would be the one effectively at the top of the pic, actually the left side of the case)
You can see that you would not want to pull the shaft out too far!
As a postscript, I tried replacing this o-ring seal several times, with no joy, the leak persisted.
It was definitely coming from the selector shaft seal and ultimately it was 'resolved' by using a sealant around the shaft, applied just prior to putting into final depth.
