Hi my engine wont start, or even turn over. it had been working fantasically all weekend,( apart from going lumpy on tick over every now and then) then after being loaded on to the trailer and taken home, it now won't start, or even turn over on the starter button ??? Ive cheaked the battery, and fully charged it over night, andd this has made no differance? What confuses me is, its not spining over and not starting, it just wont turn over?? i can hear the fuel pump prime etc, any ideas, clues to what it could be?? im very new to motorbike engines!!!!
