This is what I've found. I have the FRP Bar Clamp. Prior to installing on my 220, if you fell the bars went this a way and that a way. Even after the install they would still twist but not nearly as bad. Fast forward. I did the KX Forks conversion with a KX250 Upper TT. I installed new bushings, used the FRP Bar Clamp and I've smacked trees, dumped in on a fire road, etc. You know what, the bars did not twist AT ALL. So if yours have twisted prior to the FRP Clamp, then I would suggest replacing the bushings and then install the FRP Clamp.
