Had a weird one the other day,I was just waiting for my friend to get his lid on before getting off for a blast. Put key in ignition and turned it on,it started like a car,I was actually talking to my bud so wasn"t even looking at bike nor had I pressed the starter button. A thousand thoughts in a millisecond and I turned bike off,even my friend realised what had happened in the moment. It turned out to be the starter button,what had happened was the starter button had been pushed into its housing far enough to get jammed. It was slightly off centre to the left,no problem,using thumb nail just centered it and it released back into normal position. If it happens to anybody else ya know where to look. No such things as ghosts
