Just an update on my '08 SERK.
As you all know, I had the powdercoating flaking, chipping, coming off just inside the shift shaft support area on the inner primary. The price for the granite powdercoated and chrome inner primary are the same price. They installed a chrome one for me at no extra charge.
The rear wheel was sent in and replaced without issues. They did the Amsoil motor oil change, which they stock at the dealership, and did the other fluids as well. The performed all the campaigns for the gaskets, bolt, ACR's etc and the motor runs fine. I was not able to "hear" the motor as well with being all bundled up with extra neck muff on and all the padding back in my helmet, so I can't tell yet if my sewing machine is gone between 2500 to 3200 rpms. The oil and the movement of the rocker boxes may have helped some. But if it's loose pistons, not a chance.
As far as I'm concerned, all is fine in HD land.
Just thought I'd share my experience.
Later dudes and dudettes...
