I tried Great Foam expanding insulation. I noticed no reduction in vibration. So I went to plan B, lead weight. When I went to dig the foam out of the handlebars after about two weeks in a heated garage, The foam was only dry in the end few inches of the bars. It was still wet goop through out the rest of the bars. For the lead weight, I used two 8" sections of 1/2" thin wall conduit. Melted lead fishing weights in a small frying pan with a butane torch. Filled the conduit with molten lead. (each section of conduit took about 11/4 lbs of lead). Coated the conduit and inside of the bars with epoxy, and inserted the lead filled conduit into the bars. There is now a noticeable reduction in handlebar and mirror vibration. If I were to do it over again, I would simplify the process by removing the bars, drive corks 8" deep into the ends of the bars, and pour the lead directly in. Craig Kahler

IF, you are gonna do it, get a hose to fit on the calk tube end so it reachs all the way thru so you know it's there then as you fill slowly pull back out. pushing in and out at times FEELING that it's filling. (if you go from both ends you won't know if the center if FULL. tape some plastic over the far end so it does not just come out all over. THEN LET US KNOW THE OUT COME, have heard many ways to limit the vibration and that was one of my thoughts, but have NOT heard alot of positive on how well or if it works at all ...YET. it's sounds logical, tap a wind chime it vibrates a while for sound, now then fill it with anything and tap it, a dull sound that STOPS QUICKLY. so I would THINK it would work like a shock ABSORBER and a slight stiffener. (with out adding much weight)

what is the technique and best type of calk or insulation to use to fill handlebar for anti vibration. do you push it from one end until it comes out the other or fill it from each side? hal2006 kgreen
