Ok, new problem. I replaced my solenoid and got the bike started. Rode it for a quick half mile, then parked for a few minutes. Took off again and went another half mile, then it started running very rough. Finally, it just quit. Will start bu sounds terrible. Thinking it's a heat issue, maybe a bad coil. Any other suggestions?

Mine behaved similarly, it would run fine for a while, then act like you're describing. turned out to be a nearly invisible crack in the fuse strip on the solenoid. I replaced it with a 20 amp in line run straight off the battery and never had the problem again.

Sounded terrible how? first you need to isolate the problem. Have you got spark at all 4 corners? If not were don't you have spark? Remember a coil will effect 2 cylinders.If you have spark. You can pull one plug wire at a time to isolate a bad cylinder. Then, without re-connecting the wire pull that plug and see if its wet. If it's not it's fuel delivery. once know what system has failed you can start to troubleshoot that system. Steve

Well, I pulled the plugs after it started acting up, and checked them all. All were dry and fired when I checked them, so I guess it must be a fuel issue. It sounds like it may be starving for fuel. I have just replaced the air cut valves and cleaned the carbs. Never touched the pilot screws, my clymer manual siad leave them alone. Might start by pulling false tank and air breather to see if somethings out of whack under there. Would appreciate any other ideas.

Check the fuel pump for flow. Thake the line off going to the carbs and attach another hose to the fuel pump, put the other end in a container and crank the engine. It is supposed to flow 15oz. per minute at 3000 RPM. It will be somewhat less at cranking speed but should pump a good healthy series of spurts.

ok, I first pulled fuel lines and filter out to check for blockage, found none. Was gonna pull petcock apart, but there are no screws, rivets in place so I guess this is that "non-rebuildable" one that randakk has a rebuild kit for. I want to rebuild it because I all of a sudden devloped a leak around the lever. As for fuel pump, the weather here has decided to get a little more seaonable, say 15 degrees, and I don't have the luxury of a heated garage, so I'll check the flow when it warms a little and let you know what I find. Thanks for the help thus far.

Ok cbach, I dont know how these tanks vent, I have an 1100 myself, but could the gas cap vent be plugged causing fuel starvation?

i had that problem last year randy. someone here said to spray wd-40 in the holes in the cap and let it set. It worked fairly well but I still get the vaccume sound when opening the cap. I tried removing the cap but that didn't seem to help with this current issue.

OK, here's what's new.... I checked the flow from the fuel pump. fired it up and put the outlet hose in a 20 ounce soda bottle. Filled it in less than 30 seconds, so I got plenty of fuel. But the filter wasn't filling up fast enough and I soon started lacking fuel from the pump. So, just for fun, I readied myself for the sweet taste of gasoline and blew through the inlet hose back into the tank. Low and behold I have a much better fuel flow. Must have been something in the pick up lines in the tank. Took my first ride of the year today that I didn't walk home from!!!! Thanks for the help all!

mine had the same issue and it was a coil but it could be ignitors, wires, plugs, or coils just check them all
