2013: “This incident has been happening since the first day I have owned the Kawasaki ninja 300. I would slow down to a stop and the engine would stall. I would then put it back into neutral and restart the motorcycle. It would happen a few times until the motor gets warm, then it stops stalling. It happened to me at least 3-7 times when riding it today. This happened to me about 4 times now.”
