o7 Wildfire 250 acquired with damaged wiring harness and a new rotor/stator that was partially installed because of fitment issues. Once I removed the rotor I discovered mismatched keyways 3mm rotor/4mm shaft, made a custom woodruff key. Then saw pulse coil was about 6-7mm out of align with rotor pulse pad. Milled down the mount posts about 6mm. Done-right? Wrong. With my Fluke set on AC upon cranking stator(red/black)wire reads 40V and pulse coil reads 0.50V. when I connect CDI my coil signal is 4V. IDK what it is at the plug but spark is very very small and blue. Does anyone have any suggestions that could get me running?
