I just put the Kuryakyn Silver Bullets on mine also. I used the 2319 model instead of the 2320 because of the Kuryakyn mounts (#2375 for 54 to 58mm shrouds )I used (wire had to be external). Fit the smaller shrouds perfectly. I had to add a ground wire though because the shrouds are isolated from the frame. I removed the 20 watt halogen floods and installed 50 watt spot bulbs with a much narrower beam. Really light up the road and not so obtrusive. Wired them into my high beams for now.
If you look closely my right hand lens is already cracked. Hit with a rock within 1 hour of installing them.
