If it was me, I'd replace the pulley today. It's recommended that the belt and pulley be replaced together, but that depends on your budget. It's much easier to do the pulley then to replace the belt. A LOT easier. :-)

I have over 100,000 miles on my rear pulley and it looks nothing like that. Looks like some sand or grit got in there and wore that pulley. Thats not what Id call normal wear.

Was there any salt in that grit? Salt will eat up uncoated aluminum in short order.

Our pulleys are an aluminium alloy, not straight Al. I've ridden for many years on salty roads and other than appearance haven't detected any significant adverse effects. The only bike I owned which did, had a Magnesium alloy front hub and brake - now salt loves to nibble away at that!
I'm convinced that belt and pulley combination have plenty of miles left in them. If it ain't broke....

Thanks all for your help and suggestions. I have a primary gasket kit on order and will be ordering a new sprocket and pulley along with a belt tension tool. I want to check the tension before removing the belt to see where that's at and will also check alignment and carefully inspect the belt. I want to try to eliminate any mechanical causes as I don't want to do this again. I've already resealed the primary back in August so at least I know what I'm getting into.
We're planning to do a lot of riding next season including a trip to Yellowstone so I want to ensure the bike is in tip top shape as it seems there's not much support for the old EVO bikes.
