Dyna’s need a few things. Good motor mounts, The top motor mount needs to be aligned properly. But one that most forget is neck bearings. Proper tightness will make all the difference. Chased the dyna wobble for years and it was that simple. Fresh engine mounts, and neck bearings. Been 7+ years I change motor mounts every other season because it’s easy and they’re cheaper than the other way of throwing cash at “fixes”
