Isn't a belt about $60? I'd replace it but I'll bet it will be fine until it breaks.

I think the belts are closer to 200 bucks, and of course, you must remove the inner primary and seperate the swingarm to replace it. According to the service manual, if there is a slight tear in the middle of the belt, it is OK to keep running, but monitor the condition regularly. If it was me, I would run it for a while, but replace it at the earliest convenient time.

You've been reading those service manuals in bed again, haven't you?
