The bike was running fine all day in December when I then power washed it and put it away. Two weeks later I got it back out and it had no spark. I have checked everything electrical and found that the pick up coil maybe at fault. This was replaced with a genuine and brand new pick up and ac magneto unit but still no spark. Again every electric part was checked and I found no faults so I changed the CDI box for a brand new genuine part but still no spark. For a third time I checked every electronic part and found no faults so I changed the wiring loom for a second hand but guarenteed genuine part with still no spark. However if I put a wire between the white wire from the ac magneto and the white wire from the pick up coil it sparks and starts. Does anyone know what the fault can be as I'm really finding it difficult to fix and it's an expensive orniment :-).
I've just had a thought, if I'm bridging these two wires and getting a spark and the engine runs but very poorly I'm surly feeding the motor still with AC current and missing out the regulator/rectifier. So if this unit is for some reason grounding all the AC current and not converting it to DC for example am I right in thinking I could have a regulator/rectifier problem?
Scrap that I've tried the regulator/rectifier on a slightly older WR and it's working fine as is the ignition push button switch. I'm really struggling now :-(
