Those squared off tops will chew up the belt. IMHO it is ruined and must be replaced.
It's not uncommon for a belt and pulleys to go 100k.
What he said on both replies, Pete...
I worked on a bike a few years ago with 121,000 miles and while it needed some all over TLC, the belt and sprocket actually looked good for that many miles.
It's your bike....but, if it were mine and I'm sure most of the others here that have responded would agree, I'd never let that sprocket pull a belt on my bike with that kind of abuse. Heck, you could probably find one at a dealer that was changed for some reason that's in better shape OR get a new one but I'd hit up those "
insert your best adjective here" that boogered it up in the first place to replace it....
