I did a search and not much recent and nothing that matches exactly what I have found...
Anyway, I was removing the rear wheel to do a tire change and when the wheel slipped off the pumpkin, about 5 mL or so of black gear oil drained onto the floor. I wiped off everything with paper towels and there has been no obvious leaking since (about an hour ago). There was NO evidence of any oil anywhere on the pumpkin, wheel or weep hole at bottom of the swing arm. The bike has been sitting on the centerstand in the garage since last November. I have not taken anything apart yet - figuring to wait and see if there is anything more coming out. I am past due for some rear end service (shock refurb, drive splines, u-joint and relay arm) so I will likely have it apart in the near future. People have reported leaks due to overfilling but that is not the case here.
Anyway, does anyone have any suggestion as to what I should look for?
Any particular seals? Wondering if it might be #5 or #24 here since the oil only appeared after I removed the wheel...
@Canadian FJR reported a groove worn in the coupling back in 2011, but I think that had oil going out the rear into the driveshaft housing.

Most of the other leaks have been at the shaft with oil coming out of the swingarm weep hole.
I may end out putting the wheel back after changing the tire and see if more oil appears. Maybe it didn't like sitting?
Edit: Bike has 160,000 km (100,000 miles).
