I've been corresponding with Don at Vibranator, who makes tuned dampers for reduction of handlebar vibration.

They are located in Henderson NV. and they are in the process of making a M16x1.5 threaded damper for our FJ's which will replace our oem bar end weights.
They would like to see if any local FJ'ers can stop by their shop so they hook up their vibration meters to the FJ to get the data they need to tune the dampers.
Any volunteers?
For test readings a 1984-1990 FJ would be the best as the later 1991+ FJ's have rubber mounted motors.
Here is their contact info:
