Well isn't that interesting...
Was out in the garage yesterday working on the car. Happened to look over at the MP3 and it didn't look quite right. Gave tug on the handlebar and almost pulled it right over.
At some point during the winter I had dropped it down off the center stand to move it out of the way. Never pulled it back up. Apparently after a couple months the tilt motor must have eased off a bit.
Duly noted.
