I think 1/2 way up the window is full, but others can correct me if I'm wrong. The extended trip at a high rate of speed would spew the oil since it was high, not common under any other conditions but this maintained RPM.

I'd wait til it was warm and alternate pressure washes and sprays with the Simple Green,but some don't like to pressure wash them. Up to you.

by the shift lever, and look for a small vent hose, tied to the frame, that ends behind the fuel pump, 8-" or so above the battery. It's probably still wet with oil. Mine only vented here on my very first ride. I've never overfilled the tranny since, no more problem.
Refill the trans slowly when you service it. The oil takes a while to work it's way down to the sight glass.:eek:
