    The primary chain does not move when I pull in clutch. The clutch assembly seems very tight. I don't have the tool to remove the spring clamp on the outer bearing to get to the clutch nut.

    Just found out that the damage in the pic was previous damage. I might be back to the starter. Ouch.

    Well like BWG56 said if it just started and it's not the starter then something must be loose or worn in the clutch hub assembly, I'm sure the tolerances are very close considering the narrow primary cover so check and recheck including eliminating the starter. and report back

    I did some more searching on the part number I posted, I had it wrong it's used if having clearance issue between the clutch basket and inner primary which makes better sense

    If you remove primary cover and the whine stopped, then the only thing in the stater that could be an issue is broken shaft - or loose, or something that is hitting the primary cover???
    I'd look at the stater shaft - if not it must be the clutch hub nut or bearing - these are the only pieces that move inside there (that i can really think would cause the noise)- possible starter shaft hit primary cover - or it pushes the clutch basket gear and torques it into the primary cover or even side loads it into the rear primary cover. but to if its the clutch basket moving the nut must be loose or the bearing is bad.

    Either way, my opinion is, if its not the starter shaft broken or hitting primary cover, get a new clutch hub bearing and then as you replace it and torque the clutch hub nut you will have eliminated both possibilities.

    Having done nothing more than removing the primary cover and replacing the rubber gasket and inspection gasket and torquing everything up to WSW specs(thicker gaskets) the noise is gone. Bike started up and ran fine. Now I get to nervously wait for it to happen again or something fail completely.
