I have a friend who has a 1979 xl 1000. he just had the top end re-done abd said that the bike ran well for a while then all of a sudden it will not start. He checked the coil and there is juice to the coil. I am curious, does that bike have a stator? What and where is the stator. As far as I know, the stator is a part of the charging system? Any idea's of what this could be???
