Bought bike new. Idles at 900 rpm. Have been checking this out all day, Kinda thinking it may be front mount, Just replaced it less than 2 weeks ago. keept looking at it and slid a pry bar between washer & rubber on bottom of mount with a little pressure it mellowed the bouncing out quite a bit. Now may be way off but seems like if the bottom washer fit up tight to the rubber and got rid of the gap between them it should absorbe more of the movement. With the steel sleeve preventing this looks to me like its just working center of the mount instead of whole thing. Now with all that said is it just time for me to just hit myself in the head with a hammer for my brillant deduction or what.

Elementry Watson! Sherlock always uses deductive reasoning! I would have thought it was something with the PCIII or spark plugs myself. I hope it is something simple like the front motor mount. Good luck, and let us know when you find and fix it.

2007 Street Glide here with 40,000 kms and mine started doing the same thing at idle last fall before I put it away for winter. The bike ran great, no noises and no tuning problems just a strong shaking at idle that even made the fairing jump around. Increasing the RPMs above 1000 seemed to smooth it out. This Spring, I will try repourquing all engine mounts, replacing mount rubbers and the exhaust rear mount rubbers as per the above suggestion. I expect that problem lies with the mounts. There are many other posts here about the same thing. Someone even suggested that if you loosen and retourque the slipon mounts you may cure the problem as they tend at times to get jammed up and cause vibration.
Whatever works is worth posting because we are definitely not alone in this!

The Harley mount is too soft. Go to the velva ride front mount and your problem will be solved.
