Got a good reduction in handle bar vibration
Following on from a posting by Acat in 12 June 2010, I decided to try his suggested method of reducing handle bar vibration. I used to get a partially numb right hand after a period of riding. The good news is it works. I have a K8 DL1000. I did try lead shot in the bars and that made very little, if any difference. What I did was, (we are metric in this part of the world). The internal diameter of my bars is 17.8mm .I got 400mm of 16mm steel bar from the local engineering shop. Using a bench grinder I domed each end. I the removed the handle bar end weights and inserted the rod in marking off how far it went in. I did this for each side. For me it went in 245mm one side and 242mm the other, I then subtracted 76mm for the end weights and a further 5mm for tolerance. This resulted in the bars being 161mm long one side and 164 mm the other. The difference is probably the different shaped domes. I cut the rods to the desired length, covered them with silicone and slid them into the bars. The silicone was messy and I then used a lot of rags and turpentine on the end of a screw driver to clean out all the surplus silicone from inside the bars. I then left them 2 hours to dry before inserting some foam rubber to fill up the 5mm gap I left, then the handle bar weights. Before inserting the handle bar weights I put a thin film of oil on the rubber to stop them sticking to any residual silicone. The only thing you have to watch out for is the LH weight will want to side out before the silicone sets and needs to be held in until it sets. It was relatively easy to do and did make a noticeable difference.
