Polyurethane Vs. Rubber Riser Bushings?

I installed mine today. I recommend this mod. The bars feel much more solid, and there is no noticeable increase in vibration. In fact, the mirrors seem to shake less.
Some cautions - make sure you cover the forks and the headlight with bubblewrap or something along those lines to protect the surfaces from getting dinged by your tools. Cover the tank/instrument cluster with a bunch of towels to rest the handle bar assy on. And, be careful on the RH riser bolt. There is a ground wire and it is very easy to break the terminal off the end of the wire (guess what I have on order from H-D?).

Poly Bushings
I just switched to poly bushings, bars a lot more solid but vibration has increased significantly. At low rpm (under 2500) I thought the mirrors were going to fly off. Above that I no longer get a shake in the bars only a buzz. I've decided to try the"vibranators" to see if they can reduce the buzz and clear up the mirrors.
