I have a 2007 FXD Super Glide that has 12" apes with the factory risers/speedo clamps. The bars were on the bike when I got it and no matter how much I tighten the clamp screws (being careful not to tighten them too tight as not to strip them) the bars still will move when a bit more than normal riding pressure is put on them. Note I have internal wiring in the bars. Any good ideas on how to keep these from moving? Thanks!
