Went to replace the belt, and yup, she was about done! So, got about 4800 miles on the original. It was making a chirping noise sometimes at take off, so I guess this explains that.
The Mitsuboshi belt is a bit different, so I wonder if my OEM belt was a Bando. I also have the Gates carbon belt as a back up.
Dumb question, but should the belt go clockwise? Arrows on the belt point towards the rear of the machine?
