That is one thing I learned from experience - rider & bike down and right back up, furiously trying to start. Convince them to turn it off, give it a couple seconds - push a bit away from the track and all will be good :). Got a round burn mark on my gloves from a certain Kawi when the rider continuously attempted to fire the bike after being layed down, all it did was throw flames from the pipe but wouldn't stay running! Kept yelling to stop, give it a couple seconds. When threatened with the fire extinguisher (when the flames started catching the tail piece) - the rider finally stopped, pushed the bike a few feet, took a breath, and restarted! :)
