No, 2 new yamaha belts and new bolts installed for belt deflection.
2-300 rpm is never gained back even on a really long run like 1-2mi? If answer is no then check valve clearance.

We haven't checked valve clearance but do not think it is a valve issue, sled starts and runs flawless until the very top end. Cold starts/hot starts no issue, just does not pull on top end like they used to! It has us stumped, seems like an issue that a few people have and no one has been able to find the fix for.
