Default Shudder on an 09 FB

I have a really bad shuddering problem on decel. It's not coming from the brakes as you don't have to apply them to get the vibration. You only have to let go of the throttle and leave the clutch out.

I am posting here as I have had it at two steelerships and niether can find the problem. I have tightened down the engine mount bolts so I know the the mounts are tight but the problem is still there and I have run out of ideas.

Has anyone else had this issue? Any sugguestions on what else to look for?

Acouple of things come to mind, are both plugs gapped the same (you'd be surprised) and does the primary chain have the correct tension, possibly faied auto tensioner. The primary case has to come off for to check the chain. Sometimes a chain will bounce up and down during the decel and the vibes are felt down by your feet.
