i recently got one for free and i was a little unsure about the bolt/rubber washer setup. if someone could tell me how they split them up i would appreciate it.
The rubber washers just reduce vibration you feel in the handle. I took the rubber insulator off the stock handle and cut it so it was just a flat peice of rubber with two holes in it and used that instead of any rubber that came with the UPR kit. If you want you can replace the rubber bits with some metal washers and that'll cut out any slack. It's really up to you how you wanna do it, it's not gonna change much besides the vibration feel no matter what you do.
ok, it has two metal washers, and two rubber washers per bolt. are you supposed to sandwich them all together on one side, or do:metal washer-rubber washer-handle-rubber washer-metal washer-stock base?
