2001 YZ426F, pink wire mod, regulator needed?

I have a 2001 YZ426F and recently swapped in a WR426 flywheel and stator. I did the pink wire mod, cut the pink wire and grounded the wire from the 6 pin connector to the frame and the other end of the pink wire from the stator did not connect to anything. Hooked up my Baja Designs 100 watt halogen light, grounded the light to the coil ground and hooked the power wire from the light to the yellow wire from the stator. I started the bike and had light at idle than when I revved the motor up the light got brighter, than the bulb blew.

So leads me to believe I need a DC regulator or did I do something wrong?

If I do need a DC regulator how do I wire it? Leave my current grounds in place and just ground the regulator on the frame or at the coil ground?

Looking forward to feedback and waiting patiently for my new bulb to be sent out. Thanks

Google Ricky Stator. They'll know just what you need.

I will do that, thank you! Can't wait to do a night ride, I will post up what they say.

I called Ricky Stator today, they were closed yesterday due to the holiday. He said it depends, some bikes you do not need them and others you do. Apparently my bike needed one so I ordered it and a new bulb. Hopefully this weekend I should be able to test it out!

Where did you purchase your wr426 stator and flywheel? I can't seem to find them anywhere and when I do they are close to $500.

I was able to get it off of, yet I paid the same price roughly after having a bidding war. I did however get the complete wr426 harness, coil, cdi box, flywheel, stator. Basically all the electronics.


You need an AC regulator, check the link



I ordered one last week, hoping to install it tonight with my new bulb. Thank you for the help! You guys have fast shipping and great customer service! A+ in my book. 

I got the regulator all hooked up and light works flawlessly! Thanks again to Mike at Baja Designs and Ricky Stator.

Did you have to modify the stator itself by clipping the pink wire and resolder it to the copper wire? Or is that step unnecessary as you stayed on a AC system?

      So I have a 2008 yz450f and I would like to add some LED lights to it to make it street legal. Mainly just a headlight and a tail light and turn signals if I need to (which where I live hand signals work).
      So where I need help is getting power from the stator to a battery. Wiring from a battery to anything else I got and understand and don't need help with (but recommendations are welcome). So my questions are.
      What type of power is coming from the stator. AC or DC? Will I need a regulator or rectifier? How do I wire something from the stator to charge a battery? What would that wiring look like? Would this stator http://www.rickystator.com/product/stators/yamaha/yamaha-yz450f-35-watt-lighting-stator-assembly-06-09 work? Anything else I should know? Any help would be appreciated. Thank you.

      Alright so I’m new to the site so maybe this question has already been asked. I have a 2002 Yz426f and I want a new exhaust, it has the stock header and silencer and sounds amazing but I’d like a little more from it, I know I want the fmf power bomb header and am kind of undecided on the silencer, I see on fmf’s website that their silencer will add low end and slightly take from top end and the other way around but I’m looking for increases throughout rpm range. I do a lot of trail, hill climbs, jumps, and wheelies so kind of need good performance everywhere in the rpms. My question is what silencer I should get and the jetting I should get for the carb. Thanks

      2005 YZ450F, Athena Big Bore, Power Bomb, Q4.
      Ok.  Last fall after a decently hot day at the track, I noticed coolant leaking from the weep hole on my water pump after pulling into the pits.  Ordered an Athena re-seal kit, put it all back together and didn't really get a chance to ride it.  3 weeks ago, went out to the track, and after about 20 laps, it started leaking again.  Kept filling it with water to get thru the day, never ran anywhere close to dry or empty, jut a cup or 2 low.  Ordered a Hot Rods re-seal kit with bearing and also ordered a new w/p shaft.  Did it all again and got it back together, ran it, and as soon as it got to temp, it was leaking out of the weep hole again.
      So, what the heck am I missing?  I'm totally stumped on this one.  Is something wrong with my case cover?  Do I need to replace the w/p itself?  I'm feeling like I should've just ponied up for the Boysen in the first place, and now it's biting me in the butt.  Any help or suggestions is greatly appreciated.  Thanks!
