After a partial restoration of my 1981 YZ125, the bike seemed to run fine for about 20 minutesof dirt riding, then started to pop a little and seemed to be loosing power on hills. After stopping and pulling the stator cover we discoverd the wiring in the stator compartment was melted and smoking. Would this possibly hurt the CDI unit, or the ignition coil? I’ve found a company that produces new stators in California, but I don’t want to smoke another stator if the problem lies elsewhere.
i have never seen a melted smoking stator so something very odd happened.

No sure if you can tell in the attached picture, but if you zoom it, you can see the woodruff key slot to the center, left, and silver metal just to the right of that, where the woodruff key actually was positioned when we torqued the flywheel bolt down. I think that is why we experienced the failure.
