I bought a 1979 CX500 Custom and all I need to get the bike running is a new stator assembly. If you have or know where I can get one that works please let me know.


TIA.

The bike cranks and lights work but the spark plugs don't fire. I've tested the stator wires and have removed the old and damaged one.
i know the cdi stators go bad, but ive never heard of a completely failed one. usually when theres a no spark problem its the kill switch. did you try cranking the bike with the kill switch unplugged?

The stator was broken. It got caught in the flywheel and ripped the wiring. The kill switch is fine. I don't know how it happened I bought the bike in this condition.

When the low speed source coil fails the bike will not start. That is a common failure as the stators age. Tech in Training did you check the stator by measuring resistances before removing the stator? How to check or test the stator and pickups on a CDI Honda CX500 | MotoFaction

id be curious to see the high speed vs low speed coil failures. i personally had a high speed failure on a 1 month old stator...

and, he mentioned that the flywheel somehow caught the stator and damaged it.

Some of the replacement TI stators need a ground connection moved to avoid contacting the flywheel. I wonder if the PO hadn't installed a replacement incorrectly. That kind of interference doesn't happen spontaneously.
Tech in Training, does this bike have the stock CDI, or an aftermarket ignition? Again, pics will be a huge help.
