I'm new to this forum, so please hang with me. I have a 1978 xs650 special, not a whole lot has been changed mechanically other than: a pamco ignition, pod air filters, and cut off the mufflers leaving headers open and wrapped. With that being said I will ride my motorcycle for about 10 to 15 minutes and then it quits running. It will not restart until it cools down for about 30 to 45 minutes, during the time that it is too hot to restart it has no spark. Over the past few weeks I have had my ignition tested, and came back good other than a weak magnet in the rotor which was replaced, I have also replaced my battery, coil, and alternator brushes. Still my my bike dies after 10 to 15 minutes I'm completely baffled as to what is going on, does any body have any help for me?
