It could be the stator bell is becoming de-magnitized.

Brand new stator and flywheel.

Sounds like your getting a lot of resistance, check the wire connections and ground.

Without changing anything it mysteriously has spark again and fires right up. I'm going to clean the grounds and put some dielectric grease in the connectors, hopefully this will take care of it once and for all.

No spark again. Seem to be getting low voltage from the cdi to the coil. I'm going to try to replace the wire from the cdi to the coil and see if it fixes it. Wonder if radio shack has replacement pins

You could unscrew the BOOT CAP off and cut about 1/2 inch off the COIL Wire then screw the BOOT CAP BACK on. Also check the COIL wire at the actual coil make sure it is screwed onto the wire good and tight. Check the wires and connection on the COIL, many times they are loose and you need to crimp them on good and tight.

Didn't think about cutting back the plug wire, that won't hurt. The resistance at the coil was 40 ohm if I remember correctly, it was within tolerance for sure. The issue is power from the cdi to the coil.

How are you measuring the power from the CDI the COIL? That is a lot of voltage going to the coil about 400 or so. Then the Coil converts that to 20000-40000 volts to the plug.
If you think not enough from the CDI then just replace the CDI.
Make sure the Wires on the plugs to the CDI are good as well as the actual plug onto the CDI is good.

dont mix CDI's use what your scoot came with, the trigger should have a minimum of .5VAC, make sure you saw 2 and not .2 cause .2 will be no bueno, and if your coil is plugged in to the cdi output it will not show the correct amount because the voltage is running through the coil, Test the coil + lead when disconnected and cranking the scoot, you should see at minimum i think its 18VAC
