I carefully followed Electrex's instructions. Pretty simple really and even though the bike runs poorly, the lights worked fine...The vague part was where to attach the the cut and spliced wires I ended grounding them both, have a good spark and the lights work. I wonder if the the voltage is different with the wr stator and may require the wr CDI as well? By the way I have installed a voltage reg. as well. Hopefully I can get a answer from Electrex. At $200+ for a wr CDI, it would truly suck if it did not work either... I was told to NOT ground the pink wire coming from the stator. Just cap it off and call it good. This is how I have mine and it works great. The one thing I have learned is never buy a motocross bike to do the work of a offroad bike.
