Went on a nine day/four European country trip last week. Four, five times during the trip, when I switched off the ignition and should start the bike after a couple of minutes the motor cranked but did not start. Not a misfire, just nothing… I tried to switch on/off the killer switch but the bike still did not start. Then I turned off/on the ignition with the key, and every time I did that it started right up as it usually does. It did not throw any trouble codes. As far as I could hear it went through the startup sequence as it should. Any ideas what the cause could be?
