I was out riding the other night and my sled started to pop and misfire when I would open it up. I parked it in the garage when I got home and the next night I tried new plugs to see if that was the problem. Same thing. I left it for another night and checked the carbs and they looked fine. Went to start it up and now there's no spark. I've already put on a new coil and checked all the wiring. Could it be the CDI or the stator?? I would love to get this fixed as we just got some new powder.
