Motor mount shim
Motor mount shim
Just shimmed the front motor mount on my new to me '06 Dyna Super Glide with only 4600 miles on it. Took 3 washers and while it seems like there is less vibration in general, at idle the front wheel and bars still shake. Definately seems smoother when riding. Could it be that even though the bike has low miles, it is still a ten year old bike and the rubber in the mount may have gotten less "rubbery" over the years ?

The vehicle alignment seems to have a great deal to do with it; I needed to replace my front isolator, perform the vehicle/engine alignment, and shim my new isolator at 600 miles on the ODO. If the alignment isn't correct the front isolator is installed under tension which distorts the rubber of the isolator; once rubber is distorted, it never really comes back.
After installing the new isolator, doing the alignment correctly and shimming the front isolator, mine has remained unchanged and shows no signs of distortion. Those isolators are a wear item but with proper alignment they do seem to last; my older Wide Glides were still running their original isolators and were also showing no signs of distortion or deterioration, those bikes were also in correct alignment...
Edited to add: Cbb129, did you replace the isolator mounting bolts? I also used 3 shims on mine and replaced the OEM bolts with longer grade 8 bolts making up for the shims to be certain the isolator was properly mounted.
