Ok i have searched and read all kinds of thing this afternoon about this issue in the forums. I think i have a plan, and i need a yes or no kind of answer to tell me weather it will work. Purchase an '04 WR450 stator Apply Baja Designs mod to it, makes it one high power tap, install directly into my '04 yz450f, not requiring any mods. Get high power Electrex rect/regulator or stock WR450 Reg/rectifier, install. I will then have 150W of power for running lights and heated grips? i need confirmation cause i found conflicting info about weather or not the WR stator will install in my YZ.
