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.

 

Have you looked at the front motor mount?

 

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?

 

Is the Mount clearing the frame x-member,as described on Service Bulletin M-1324,i found it & attached it,this cured the vib on my last Dyna.

 

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.

Check the service bulletin referenced above. The inadequate clearance they mention in the front motor mount is a common problem, and can show up even on new mounts.

 

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.
