Weird sound diagnosis
Can anyone tell me what I'm hearing with the pitch of my exhaust changing? I have never encountered this before. Engine wasn't overheated, coolant is good, and the plug looks good (no detonation). Anyone have a clue or been through this?

+1. Is it making far less power at low rpm when the exhaust note changes?
Time to clean the power valve and/or replace the bearings. |

Thanks guys. I just did the top end 55 hours ago. Everything was fully cleaned and inspected. Even replaced one of the bearings on the powervalves. Oh well.
