I just installed a new detachable back rest on my 08 wide glide and seem to have picked up some extra vibes. Anyone else notice this with there backrest? I have not tried it with out the back rest, will give that a shot tomorrow.

 

Yep... wrapped rubber around the mount and solved the problem.

 

Yep. Can get louder than the pipes. I mostly just use the detachable backrest when something's strapped to it or someone's leaning against it. That calms it down. I stretch a bungee from the bar to the fender rack when nothing's against it. That also clams it down.
