Dead cylinder GS1100E
1982 gs1100e #2 cylinder is dead. Bike idles and starts fine. #2 plug looks wet fouled and smells like fuel. Has spark. tried swapping plugs between #1 and #2 and same problem. is there something that could be making that carb super rich to wet foul the plug? maybe the spark isn’t strong enough? also the #2 carb has the vacuum line from the petcock going to it don’t know if it could be a vacuum problem? Bike is all stock.Tags: None

Have you done valve adjustment?
Have you checked compression?Rich

Had the same issue and it was the vacuum line, or rather petcock in general. Try removing the vacuum line from petcock, not the carbs, and block it with an oversized bolt. Then turn the petcock to PRI setting and give it a go. Probably a good idea to make sure plugs are clean prior to this. Also remember to turn the petcock dial back to regular/off position after you try this, it may flood your carbs or engine.
Pingel sells a worthy replacement if you need one. They have one with vacuum line as well as one without, which is what I got. Bike runs amazing, just had to pick up a habit of turning the fuel off at or shortly before your destination.1980 GS1100E

Also when I took the bowl off fuel seemed at good level (float bowl like 80% full)Rich

Originally posted by radek22 View PostThere's the fitment chart below. Delivery is fairly quick, bit pricey but a great product so far imo. I got the single output 6211-CH, but they have dual for vac line as well. Measure the distance between the adapter screws, either 50mm or 44mm, gotta get one of these too. Hope you'll get lucky like I did, and won't have to file the tank opening. Use gasoline resistant teflon tape on adapter screws (orange color, much thicker than regular), at least 4 times around the screw as tight as possible ( I think I did 6 or 7). Fuel valve needs about 3 times around the thread. I'm loving mine, hope it works for you.
