I recently purchased a GPR stabilizer from a shop on EBAY. That may have been my mistake but after I installed it, the bike seemed to sway left to right at slow speeds. I kept riding it because everyone told me that it just took some getting used to. I took it to a local shop today for suspension adjustment and when the mechanic took it for a test rided, he asked me if I noticed the sway. It makes you fight the bars to keep the bike in a straight line. I told him yes and he said he didn't think the bike was rideable. We worked on it for about an hour but I eventually took it off and rode home, it was much better. Could this be a bad damper or can my steering be off and the damper is making it noticeable?
