Ok my bike has been running very rough as of this past week and when looking for possible reasons why I noticed something odd. On the rear cylinder, right side when sitting on the bike, the plug is sending sparks out. I know it is supposed to spark on starting but this is a continuous sparking and you can hear the little clicks it makes. What could be causing that? None of the other plugs seem to be sending out any sparks. Is it a bad plug, bad wire, or something else? I am at a loss. Thanks!!
