Based on a thread by Mr.Wright I thought I would give weight at the ends of the handle bars a try. My right hand starts to tingle after maybe an hour riding. Could be my Carpal Tunnel coming back, it's been 20 years since I had that operated on. Going to see if this does anything. Started out finding a fiberglass handle that fit inside the handle bars. Cut the maximum length I could fit in the bars on the right side. Five inches before hitting the wires that run through the bars. Found some PVC pipe fittings that fit in the ends of my tube and after smoothing the ends up on a grinder epoxied one end in. Filled the tube with lead shot I had on hand and sealed the other end. Wrapped it with a little electrical tape to tighten it up a little and tapped into the bars. Not sure if it should be tight or a little loose. I had read about matching the vibration of the bars with the insert that you use, how ever you do that. First test will be to see if the mirror on right side vibrates less than the left.
