I built handlebars that are mitered so they don't have radius's in the corners so I was worried about getting the wires inside the bars. I went to WireCare.com :: Your Cable Management SuperStore! and got some wire harnessing filament. Wow did that stuff work well. I have only tried the left side so far but that stuff slid right thru the tight corners. No lube or anything. looks like a much more quality item also over that plastic stuff that comes from harley.
