Primary

I own a 06 dyna low rider with 6078 miles, and I recently noticed a whining, or rattle on the primary side. No warranty left, so I went to the internet and found threads concerning the input primary bearing and race. Also have heard of stator problems. I understand that Harley is willing to pay for replacement parts and labor should I call them, dealer says they have to tear it down. My bike has a definite whine when in neutral or downshifting. Noise goes away when I put it in gear. or engage the clutch. Dealer is acting stupid, like they know nothing. Anyone out that that can help?
