I didn't change anything electrical. Everything ran fine stock. I returned the engine to stock minus the rag joint drive sprocket. I seriously doubt the upgraded drive sprocket is causing the no spark issue. It also doesn't explain why when I coasted to a stop the engine died and I couldn't start it again when it was running fine seconds earlier. It doesn't explain why neither the upgraded or stock CDI are working. Not that I don't appreciate any help. But putting on an expansion chamber and carb should not cause a no spark response. Sluggish power, bogging, performance gains yes. Not the latter.
