Hi Jim

I'll check my "X" coil ohm values tomorrow night. I had a similar problem when I got my bike. A quick check is to test the readings across the three wires from the stator. If I remember correctly I had one combination showed open circuit (no reading at all). One coil has two wires coming from it the other coil is in series with the first coil (joining wire from one coil to the other and then up to make third wire to CDI.)

Where's a piece of paper when you need it!!!!!

I'll get the readings for you.

Regards

Hi Jim

Coil values from the three leads.

White / Red = 90
Red / Brown = 472
White / Brown = 560

Hope it helps
