How are the idle vibrations? Spoil your view thru the mirrors?
If I understand the physics correctly, the engine tilts back under Accel and forward under Decel. If that's correct, I'd strongly suspect the front engine mount/isolator. May need shimmed or replaced. Very common Dyna gremlin. The front mount takes a beating and some have been reported to last only a few years.

Welcome to the forum.
Maybe you can share some details of what you're riding like year, model, mileage, mods, recent service history, etc. And where the vibration is felt, if it's related to road speed or gear.

It worked for me - took care of 80% of the vibration. I definitely want to get a Predator, but until I do, I'm glad that I shimmed.

No... no need to shim with the Predator mount.
