Vibration worse after poly bushing install
08 FXDL...
So added 2" extension to my stock risers. Put approximately 100 miles on them with the stock rubber riser bushings. Minimal vibration but decided to try and remove even more vibration by going to the poly bushings. Put about 200 miles on her yesterday and noticed MUCH more vibration now but only on the right grip. Left side is just fine.
Thoughts? I'm going to disassemble/reassemble this evening to see if that helps.

Talk to me about that. What do you mean?
And thanks for the reply.
EDIT: Never mind. I see what you mean by solid bushings.

Yep...I'm slow. Discussing with some engineer types here at the office and they're falling in line with what you're saying. Think I'm going back to rubber.

Polly is definitely harder. I blew out 2 stock rubber motor mounts on my camaro. Switch to Polly, it lifted the motor and tranny back up where it had to be but could feel it. I lived with it though because never had a problem again.

Are you using HD or aftermarket. I haven't noticed any dif with HD Brand ones. They work great.

If your bars are not too high, your fine with the rubber bushings. If you have tall bars, the rubber allows way too much flex and you're bars will really feel sloppy / loose.
