why not abandon your ac power and just run a new line to your battery to get dc power?
This would be easier, however the potential for running down the battery with its minimal charging system would be much greater.

get a regular old car headlight plug, get a 3 way toggle switch, put the hot wire to the center of this toggle, then a short whip of wire from the toggles other posts to the car plug wires, take the car plug ground to the stock ground of the bike, mount the toggle where ever you like, i mounted mine just to the left of the headlight out of harms way, vola hi beam low beam,
plus a helmet light, i am currently running a middle of the road h4 blue tint (cool factor) 55w 100W, seams to work fine, i see PIAA makes a bulb that only draws 55 w and is equivlent to 135w or something like that, i will try that next,
so far this set up lets my ride anywhere with no problems

It was made for the YFZ Quad, but it fits our WR450F´s
I have just installed such in my bike and am running a 8" HID 35W
The trailtech kit makes about 100W but will be enhanced with their flywheel which has stronger magnets built in.
You can also check out Baja Designs website and make a mod to the oem stator but it will never be as powerful, and you will always need bigger rectifier.

Actually, the stock headlamp on a WR is running high beam. So you will need to add the low beam if you want to use both elements. I have done this with great results using the K&S dual sport headlamp switch. It was detailed in this forum some time back.
the stock head light is wired only for low beam...
See it at think link I found in the search section of this forum

It is plug and play. Here it is on an 07 WR:

There is NO WAY you will get 125 watts DC power from any mod of the stock stator. Look at the picture above. Note the thicker-than-stock magnet wire? The thicker wire allows higher current. With a single 16 awg output, you will get about double what a stock modified stator can put out.
The stock core uses smaller magnet wire to allow for more turns/pole (remember they are not using all the poles for each output). You need a certian number of turn before your voltage gets high enough to produce 12 volts. When you increase the number of turns by joining the outputs, you get more voltage but your current capability is not increased. More voltage is not a big help as it is shunted by your regulator.
We stopped doing modifications to the stock stator back in 04. Low output and vibration failures gave us too many problems. We only saw vibration problems on the ATV's than ran sand (lots of high rpm running). After this, we started stripping the entire core and rewinding from scratch. This did much better but the thin overmold on the OEM core eventually fails and the stator starts to short out.
In my opinion (based on test data), if you are combining two outputs into one, it does little good. You end up creating more heat and getting only minor improvements in DC capability. If your going to run a single output, run one that is optimized both in number of turns and wire awg.
Take this for what it is worth - just another post. If you want hard data, bring the machine by. We will put DC loads on the regulated/rectified stator output and tell you exactly what you can run.

I like to tell people what they can realistically expect, not what they can get of the run at red line.
If your not getting a dead battery, you have enough power. If you make too much stator power it can lead to heat problems. Your better off not running any more power than you need.

We like to see ability to run a 35 watt main HID, a 30 watt HID on the helmet, E-Start and Fan. You cannot do this with modified stock.
Back in 04, we were modifying stock cores. While they worked for many, we saw too many failures. As this can leave a customer walking, we gave it up and tooled a core to do it right. We only recommend stock system modification for KTM's.
Our phones are a problem - sorry about that. We have a brand new facility that has more phones, more room, better production capabilities.... We will move in May:
