Dyna vibration problem
I have an 05 superglide custom that I bought last year. It has always had what I thought was too much vibration. With the help of a cramp buster I adapted to the inevitable numbness in my throttle hand. A little over a month ago I had my stock tc88 upgraded to the stage ii se 95 kit. Now not only is the vibration in the handlebars worse, but I now have vibration in the foot pegs. Two weeks ago it vibrated the seat screw out of the fender. I took it back to the dealer and they claimed that two of their techs test road it and didn't feel any excessive vibration. Tonight after riding 25-30 miles I pulled into my driveway and the top crash bar mounting bolt cracked in half. I am at my wits end at this point and I'm looking for any suggestions that might help.
When I initially picked the bike up after the engine upgrade they told me that since the race tuner had a download for the Harley 95 kit that it didn't need to be dynoed. But I overheard them tell someone over the phone that the dyno machine was down. I called them on it when I dropped it off for the vibration problem and they insisted it didn't need a tune. Not sure if a dyno would smooth it out any, but it's more about the fact that I felt lied to and with it running this rough I feel like they'll do anything to skirt any responsibility in the matter.

I replaced the front motor mount over the winter. I also tried shimming the mount when I replace it, as suggested in some other threads on this forum. It didn't seem to make that much of a difference, so I removed the shims.

Did you do engine alignment as well? Also do your vibrations correlate with or occur at certain RPMs?

I did not do the full alignment procedure. When I changed the mount I let the bike run 5-10 prior to torquing bolts. But I have bags on the bike and only have a bike jack, no lift, so I really can't get at that rear mount too easily. When I took the bike to the dealer I asked them to do the vehicle alignment because I couldn't. But they didn't because they felt it wasn't vibrating excessively and therefore was unnecessary.

And I did lol at the mount when I picked it back up and I believe it had plenty of clearance. I will have to look closer at it when I get off work. And also read that notice you attached. Thanks for the info.

If your MoCo tune for the 95 kit was anything like their Stage 1 download (which is crap) your bike will vibrate like crazy.
I didn't realize how much mine vibrated with the Stg1 tune, until I bought a separate tuner package and got rid of the MoCo's tune.... night and day difference.
