We have a couple of options with this setup.
Like the XL and XR, this bike uses both AC and DC circuits. The white/yellow wire running to the front of the bike runs the headlight on AC power directly from the alternator. The ignition coil has a dedicated AC coil coming from the alternator, and everything else is getting power from the pink and yellow wires that are run though the rectifier and to the battery.
I'd leave the ignition coil alone and keep it on its own circuit.
Next step is to replace all of the bulbs and the battery with 12V versions. You should probably replace the horn as well, but if you're feeling lazy you might get a few uses out of it before it pops.
Here's where the options come in.
The easier option would be to replace the existing rectifier with a combined 12V R/R,ensure all your bulbs are LEDs, and then wire the headlight to run from the brown/white wire instead of the blue/white. You should get the total wattage draw low enough to make this work, but a voltmeter might be a good idea until you're sure you're not going to kill the battery.
If you want to get the full charging out of your system and still do a 12V DC conversion, you're going to need to pop open the alternator and float the ground on the white/yellow coil. You'll need a second R/R to make this work, but you shouldn't have any power issues.
And another option is to try an LED headlight bulb on the AC circuit along with a 12V AC regulator. The bulb will probably flash a bit (especially at low RPM) since LEDs only allow current to flow in one direction, but you might be able to avoid tinkering with the alternator if the power output from option one isn't cutting it.
