first off, already searched...getting mixed answers. we have a 02 yz426 motor and cdi with a wr426 stator and flywheel. the stator has 1 yellow and a pack of 6 wires.... we DONT want to run a battery so the yellow lead will go to the headlight and grounded from there. i'm reading TWO different wire mods for this.... 1. cut pink wire from coil and solder to existing copper wire grounding terminal and 2. unsolder grounding wire of the lighting coil, cut pink wire from coil and solder to grounding wire of lighting coil. then cut pink wire just before the harness connection where only one side will be grounded and not exactly sure where the other pink wire goes.
