I have a 1976C xs650 which has a problem linked to the right cylinder. The bike will run great on both cylinders only if I just rest the right spark plug lead ( not connected to spark plug)on the top of the plug. If I connect it correctly to the plug the bike only runs on the left side. Pull the lead off and just keep it a half an inch of the plug they both fire. It would appear that its earthing the plug lead as soon as you connect it correctly. Does that make sense? I have swapped leads and caps between both sides but the same problem is on the right side no matter what I change including coils. Help it's driving me insane.
