Ok, I just went through this process and it is a really easy and cheap (free) way to make your bike look just a bit better if you want to keep the stock look and want nice visible signals. I also plan on buying some spray tint for the signals so that they are black/smoke.

Basically I just followed the steps from this website (http://www.cbr600f4.com/index1.htm). I am pretty sure this has been posted before but I couldn't find it and wanted to share my results.

This is easy, really easy basically do this:
1.) Remove the signals (1 nut and pull out wires)
2.) Remove the spacer by inserting a screwdriver in where the wires feed in the spacer and taking the screw out, keep this screw, this is the one you need to remount.
3.) Remount signals: to do this turn the mounting bracket that the signals were on the opposite way, and on the inside instead of outside of the bike. Feed the wire through the larger hole and put the screw through the bracket and into the back of the signal and tighten (grab a washer from your garage to go with the screw)
4.) done...test to make sure it all works.

Good job Bob. There's always a great sense of satisfaction completing you own project. Good luck on your next project.
