If I'm looking at the wiring diagram right it looks like the only wiring runnng in and out of the left coil is a black wire to the cdi and the red wire up to the kill switch on the right clip on?
This looks like inductive ignition, not CDI then. Oscilloscope needed to troubleshoot output signal from CDI to coil.


1. Test for +12v power to coil on red wire on both coils.

2. Then test for momentary grounding of black wire when running. A 'noid light can be used.

3. Have you tried swapping plugs and coil-output wires between sides? Could just be bad coil output wire
