I've got one too, you've probably trashed the coil, maybe it was bumped when you swapped rings. I had to replace one on my son's '83. Hope this helps, and keep us posted!

Take a look at the CDI box. There should be a wire harness that goes to the coils, and a single wire that connects to the ground. disconnect that single wire, and check for spark. Be careful, as the engine may run. If so, you will need to re-connect the wire to kill the engine. If you have spark, just trace the ground backwards. You may have a kill sensor on the throttle, which will kill the engine if the carbs are frozen open, and you let go of the throttle.
