[RoadGlide07]

Thanks for the update. It is greatly appreciated. I tried to get back to customer service today but it is always a 10 minute hold on the phone and then they will call you back.

I have a 07 RG with 1500 miles. It has the same clatter. It is fine when engine and transmission are cold but the hotter it gets the more noise. Somebody suggested that it could be the "new" automatic primary chain tensioner and this makes sense to me. There could be additional slack in the chain or not enought tension is being applied. Since it happens at relatively low rpms and it more noticeable on the rubber mounted engine seems to hint at the additional vibration causing primary chain clatter.
I would definitely like to try the old style fixed tensioner to see what effect this had.

Thanks again.
