I do not have a spark going to either of my plugs. I put in new plugs, inserted them into the leads and turned it over, no spark. I have the service manual, but have no idea where to start to test the different wires and parts. I would think it is the CDI box or stator. The scenario was -20C and the quad died after running well with no issues. It was backed off a trailer and when it was put into forward gear it died. It backfired a few times really loudly and now no spark. I have checked wires runing out of stator to CDI, they appear ok. Plug wires appear ok. Any ideas? I have read lots about changing over the Ducati ignition to the Kokusan system, which I can do, but not 100% sure that is what I need.
