Excellent point! I'm with Vic the alignment job should rectify all bad vibes.

I still think a good alternative is to fill a new mount with a windshield sealant like CRL7711 a butyl rubber type sealant. I have used this on turbo Dodge engine mounts that used to tear out, almost doubling their life span and not greatly increasing the vibrations to the passenger compartment.

what about the guy who shimmed his front motor mount with washers?
seems less expensive and more preventive than waiting for it to fail, then replacing it.
if mine starts to vibrate bad, i'll check the alignment then go this route.

I replaced my mount and had it shimmed. The engine has settled and is now sitting on the rubber again. I guess i just want better rubber that won't wear out. As cbz1200n had mentioned it all depends on the the stiffness of the polyurethane. They make them in different stiffness. I was planning to use a stiffer mount and shim with industrial isolation pads.

As a newbie to HD ownership ('01 FXDX) and a newbie to this Forum, I would love to see a different material available to help with the vibration.
My eyeballs vibrate so bad I can't read street signs unless I lift my *ss off the seat.

If that's true then there is something seriously wrong with your bike. My Dyna is fifteen years old, and even before I replaced the engine mounts a few years ago it didn't vibrate that bad. What I experienced mostly, when I had bad mounts was a lot of vibration comming through the footpegs. I had owned a Dyna before, and knew it was excessive. It turned out to be the mounts.
