Couple questions. My new XL883 is not to bad of a ride, but I feel the bars could come up just a tad, and back maybe a couple inches. The main thing is, I don't want to mess around with the wires/cables/brakes. How much can you get away with on rise and pull back with stock stuff? And of course, what bars would you use in place of them? What is the material of the heat shields on the exhaust? Is it chrome plated mild steel or chrome plated stainless?
