GL1000 fuel issues

Postby tovsenr » Tue Jul 26, 2011 4:18 pm



I have a '78 GL1000 which I have been working on for a couple months. I've replaced the Fuel lines, fuel filter, timing belts, coils, plug wires, plugs. I've run several cans of Sea Foam through. In general it runs pretty nice compared to when I bought it, except every few hundred miles it will kill on the highway and I end up pulling off and working with the throttle, let it sit, work some more and after 5-10 minutes it starts up and runs like nothing is wrong. It appears to lose fuel to all 4 carbs at once. After replacing the fuel lines it ran for 300 miles and then died the second day. Would anyone have any ideas?

Next time it quits,open the gas cap.If it sucks air in,the valve in the cap is plugged and creating a vacuum in the tank fuel starving the pump.

My bet is something in the electrical system is overheating. Not the coils, as they do not both go bad at once. So what kind of ignition do you run?
