So after cleaning it and installing the new part, I put the carb back on and tried nudging it back to life with another shot of starting fluid.
Now it isn't sparking again. What's odd is that the sator is now showing around 60Vac instead of 80. Only about .1/.2Vac is arriving at the ignition coil.
I took the stator and magneto from another bike, put them on the bike I'm trying to fix and got the same results from the VM. This was with the trigger coil that was on the donor bike.
So right now I'm out of ideas. The new trigger coil did produce a spark, the bike tried to start then suddenly, all on it's own, it's back to not sparking.

.1/.2Vac is arriving at the ignition coil?? Well we know that is not good and won't arc. Stator is down from 80V to 60v..
.odd. But it started to spark then stopped. Tells me something is shorted and burning a wind in the pickup or stator...possibly. Even a stator with only 60 volts will excite the coil and induce a spark. Weak yes..orange in color but it will be there. The only thing between your stator and Coil is the CDI. But you said you swapped CDI's so that rules out that the Electrolytic Capacitor in the CDI is bad. This sounds to me like a bad ground..or a short to ground from a hot wire. Usually the short to ground is found in the kill switch wire in the handlebar switch set or CDI itself (from my experience) Sad to say but my Dad was an Electronics Engineer and you got stuck with me.. The one who chose the Medical field vice the Mechanical or Electrical field. He did drill me hard as a kid on Watts..Amps..Volts..Current..Resistance..Ohms law and all that stuff. But still..we WILL figure this one out..
