I'm new to the scene, bt I have been looking in to it a bit myself. The options seem slim, but at the very least it looks like an aftermarked stator is required, or a swap for a WR stator (not a simple swap, it involves the flywheel, etc).

All I have been able to find when I looked are 35w stators in the aftermarket. Good Luck

i just bought a lighting stator off eBay for $69.95. simple swap if you have a flywheel puller.

Will you let us know how that works out? 35w seemed a little low on power. Are you planning to run a battery?

Thanks

EDIT: That headlight appears to be a 35w headlight. I would assume the stator puts out 35watts maximum, so I would expect a lot of dimming near idle, and if you add a taillight...

You are going to find that stator will run 20 watts at 5000RPMs.

Thanks for the heads up. Can you tell us why lighting stators are so hard to find for these? I noticed you don;t even list them on your site. I know there used to be an external 200w, and I think some 100w stators. Is it the age of the bike, or do they jsut not lend themselves to being wound with a lighting coil?

Thanks

The stock YZF stators are very small in size to save weight and reduce the power lost to the generation of electricity. The bike was built as a single purpose race bike, so all that the stock magneto will do is run the ignition. There simply isn't room to construct a reliable ignition system along with a lighting power source that has any capacity to speak of.

Your alternatives are to either replace the flywheel and stator with WR426 parts and modify the stator to suit the YZ ignition. The WR stator has much more capacity in stock form, being built to do this job, and can be rewound to be even stronger.

The externals were expensive, awkward, and unpopular, so they have been discontinued.

Your alternatives are to either replace the flywheel and stator with WR426 parts and modify the stator to suit the YZ ignition, or build a battery-only system. The WR stator has much more capacity in stock form, being built to do this job, and can be rewound to be even stronger.

I followed the instructions found in the "common threads"....

When I did mine, I went with a Stator from Moose, quality was not great since it failed after one years use. I since had it rewound and have had no issues since. These guys also make a stator for the YZ, not sure what year your bike is.

Good luck!:thumbsup:

The stator i mentioned putting out 20 watts was in fact a Steahly stator. We purchased one a few week ago just to test the output. The WR parts are the only way to go.
