can engine oil come from this bolt threads..
saw this then checked my oil and it was at the full mark. I normally run it lower on the dip stick. I saw this after a 300 mile ride. I removed about a half quart and went for a a 2 hour ride today after I removed this bolt and put some liquid Teflon on it. didn't see the leak when I got home.

That bolt holds the outer primary chain case to the inner chain case.
Has NOTHING to do with engine oil levels, it has it's own level and fluid chamber.
And I assume some kind of touring bike.......what year, model?

And yes if main shaft seal is bad engine oil could get in primary.

that oil came from that bolt. this has happened about 3 times over 5 to 6 years. I believe it has happened after me doing an oil change. probably overfilled it.
