09 Road King-150 miles on new bike. Occasionally at an idle in neutral I get an occasional whirring noise that sounds like it's coming from the primary. I think the noise starts when the idle heat management kicks in. Any ideas? Checked primary case oil and it is at the proper level. Any inner primary bearing problems or is that problem behind us?

 

Probably just the auto primary tensioner ratcheting a little on the tight side. Should not have to worry.
