hey everybody my 250r is not running at the moment sometimes it has spark and some times it doesnt when i pulled the plug and then check it it had some very dull spark and then other times none.... I am thinking it might be the magneto but I was talking to a guy that has a 86 and said he had the same problem he said there is like a plastic plate in the case that sometimes comes loose and the syptoms include weak or no spark does ne one have any input please send me a private message i dont come on much
