'01-02 WR/YZ stator crossover

Recommended Posts

Not sure what I'm missing.

 

I bought a '01 WR250F that had a YZ stator with no light circuit. The bike ran fine, but I want the light.

I bought a WR stator and flywheel from Ebay and checked the coils against my service manual, all within specifications.

When I installed the WR stator I got no spark. No output from the CDI (checked with a Fluke 99b scope).

I put the old YZ stator back into the WR and she fired on the first kick.

The WR stator coils still check out good.

 

Can the WR/YZ stators be swapped around?

 

Is their a difference between WR/YZ CDI or harness?

 

Whats going on? Where should I go from here?

Sounds like you are missing the WR CDI box, the YZ stator wont work on there unless you had the YZ box to go along with the stator.

Okay, but why? What's different about the wiring? The connectors ate exactly the same. I have the WR wiring diagram. Is their a differences? Someone on here has to know.

Each box is slightly different in one respect to match the stator.

In Search Of 01-02 YZ250F wiring diagram. Specifically the stator/CDI wiring. I have the 01-02 WR250F but believe their is a difference with a floating center tap. I can not get the WR stator to work with the YZ CDI.
