My brother has a 1200 harley sport custom. (shoot me later for bringing up a harley question:harder: :spank: ) the engine will be running fine and then start running like crap, and then die. after a few minutes it will fire up and run a couple of miles and do the same thing again. we replaced the coil and still does same thing. could it be electronic ignition?
any help is apreciated and thank you in advance.
