Here is my attempt to come up with a mirror that suits me. I do like the look of the OEM Yamaha handguards so I made a bracket out of a piece of one inch aluminum flatbar(building supply store). I made most bends in the vise over a short piece of bedframe angle iron with a rounded edge, because a sharp corner like vise jaws will cause the aluminum to crack. The bend that goes around the handlebar, I just wrapped around the handle of the vise(pic)( I had to build up the handle slightly with electric tape to get close to 7/8 diameter). The bend(twist) after that( which changes the direction of the flatbar), I put a piece of pipe through the handlebar hole and locked it in the vise between two small pieces of wood and gave it a quarter turn with a crescent wrench with electric tape on the jaws(pic). Once all my bends are done, I center my plastic handguard and mark my two bolt holes. I drill those two holes, and drill the hole in the end for the mirror, and then drill the one hole on top of the bracket at the handlebar end(when I clamp the handlebar end almost tight over the handlebar, then I can drill my second hole and push the bolt through). Once the four out of five holes are drilled, then if I want to color match, I can get the appropriate size shrink tube(40mm flat measurement for 1" flatbar) slide it on and heat up with a heat gun. Black shrink tube was available from a local electrical supply store, blue appears to be available but may take 3 weeks to get here. The only 3" mirrors that I was able to find with a ball joint for adjustment and a short threaded stem for mounting, was also a 3 week shipping item. As I was putting this together, I realized that a portion of this flatbar bracket could be used to add a mirror to an existing oem Yamaha handguard bracket(pic), or if I just preferred a set of handguards without mirrors, I could get away with 3/4" aluminum flatbar brackets. All fairly inexpensive.
