Long story short, if you have belt vibrations and the belt is set at the factory recommended 220-250 Lbs, you might ought to look at this vibration Dampener. Here's my take.
Bike came from the dealer with 220+ in the air tension on the belt. Belt was so tight the motor was slewed over, belt against the front left pulley flange and the rear pulley flange (right).
I lowered the tension to 160 lbs with the wheel up, noticed the vibration went from a 70-72 MPH constant teeth chattering harsh vibration down to around 60-65 MPH, with a much less harsh, softer tone to the vibration.
Encouraged by this, I lowered the belt tension to the minimum standard I'd ever seen, 120 Lbs with the wheel up. Vibration came down to 55-60 MPH, with a mild flutter on hills and acceleration. Most time smooth, but came and went with the load.
So I bought and installed a Roadster Renovations vibration damper. This is a top notch piece of equipment, and the installation took about 45 minutes including taking the panels off. He even includes a nice block to align the roller with the belt. Stainless steel arm, steel bracket, grossly overbuilt. Should last forever.
So the instructions say spin the wheel and/or ride it. I figured I couldn't observe the roller in action while riding, so I lifted the bike, parking brake off and in neutral, and used my variable speed 4" belt sander to spin the heck out of the wheel and belt. Hey, no codes! But then again, I was always doing things differently. Had to tweak it after the spin, get it perfect. Took it on my test run route, the miles I test tires and vibration on. No vibration. Smooth as it can be. Of course the engine still has vibration, I still have some tire shimmy, but all or almost all the belt vibration is absent.
So, seriously, my opinion only FWIW. Vibration, lower belt tension + Doc's damper= Problem Solved.
