I've just done this.
It was pretty easy. There are two bolts on either the side of the indicator light box that holds the whole assembly together. I think its a 12mm. Anyway unbolt it and remove it. You will have to disconnect the wiring harness from inside the headlight housing. The headlight can be removed by unscrewing two screws at the 4 and 8 o'clock position. Be sure mark your ignition switch for the "on" position since the position markings are part of the box you're removing.
As you disconnect the wires, turn the bike on and make sure your headlight is still working. I don't think there would be a problem but it's always best to check. If all is well, you can either trace the wires you aren't using and disconnect them further, or if you are feeling froggy, cut them. I traced them to junction just above the coil on the left side and cut them there.
I also removed my left side switch housing, choke lever and clutch switch. If you want to know how to do that, hit me up.
