Not sure if this will be helpful or not but it seemed to take care of a vibration I had that was driving me crazy. My 16 RGS has 8200 miles on it and it had this vibration that started about 1500 miles ago. It would come in and be noticeable between 2500 and 3000 rpms and it would go away if I pulled in the clutch. I could feel it in my handlebars and my left mirror would vibrate where vehicles behind me were blurry. I checked tires, wheel bearings, and exhaust for loose or bad parts. Besides my rear tire starting to cup, I could not find anything else wrong but the vibration was still there. I looked at the motor mounts and they looked good. I then inspected the engine stabilizer. I found it to be stuck and not able to rotate freely and it was twisted and stuck rolled forward, if that makes sense. The bar was not able to twist on the ball joints. I checked the torque and that was fine. I did lube the ball joints on both ends and freed up the shaft so it could rock back and forth by hand where before it was dry and stuck. I took the motorcycle out to see if it took care of the vibration and it was gone. It rides as smooth as it ever has. Not totally sure why except it was transferring the engine vibration straight into the frame since it seemed to be in a bind.
