I noticed that my 08 ultra does that too if I baby it. This is my first experience with the auto primary chain tensioner ( don't understand the need for it ). Shift at a higher rpm and I bet your clank goes away.

Thanks I will try that but I only hear a slight tapping or knocking when I first start it up,then it goes away when the engine warms up to temp.

Did you pull the cover off and check the oil level?

Sounds like a little clutch noise due to cold oil. Slight drag til it warms.
