I was just back out there and the whirr is definitely coming from the starter motor spinning freely. No grinding or crunching or anything. Makes a good case for the Sprag clutch I think, but I am the worlds worst mechanic, so I'm not a good judge.

Looks like I'm getting a tow in the morning.

This is an '07 America. Obviously not in the "earlier bikes" category, but I should still be under warranty.

Ugh...This sucks, it's supposed to be 80 and sunny tomorrow.
