Do you ever get up to and past 110 mph? I also get death wobble then but can power through it up to 125 and kinda lay down on the tank.. Tucking in behind the bars does eliminate death wobble..

In all fairness it should be noted that when it comes to vintage British motorcycles, if you do any action beyond leaving it stashed in your garage, cracks often follow..

Bill Dodge from Bling's Cycle has been building rigid frame bikes with modern HD drive trains. I am pretty sure he takes Twin Cams for Touring bikes and mounts them rigidly, into a rigid frame.

Look him up, maybe some of your answers are there, good luck.

I would think that vibrations are not an issue with rigid mounts in a Dyna frame, but I agree the forces acting on the swing arm mount could be a problem.
