I have an 06 1100 Silverado. It has been under its cover since October last year. It made it to about 50 degrees today so i figured I would see how she sounds. I turned the key and the fuel pump ran for a few seconds as usual. It fired up but was a little rough and wouldn't stay running unless it had some throttle. I could smell a strong gasoline odor and then saw lots of smoke coming off the right side of the motor and pipes so I shut it down.

After investigating it seems that while the fuel pump is running, gasoline is running out of the tube with a 90 degree elbow that comes out between the two carbs and then a rubber hose runs down behind the aircleaner. As long as the bike was running, the gas was just pumping out onto the motor. I'm glad I didn't have any flames to contend with. Also, but boots that connect to the airbox were pretty saturated with gas.

Any input would be appreciated.

It sounds like a stuck float. You can try lightly tapping on the carbs with a screwdriver handle or small hammer. All you are trying to accomplish is to get the floats to free up. Some times this will loosen the float valves. Verify the floats releasing by just turning on the ignition switch, without starting the engine, and listen for the pump to stop running, it should not come back on again even after 1-2 minutes.
Hopes this helps.

It could very well be stuck float,especially after settin the winter, it doesn't take much sometimes to stick or unstick, as Doug says, tap around on the carbs, also I would add a good carb cleaner, lots of the guys like Sea Foam and it is good stuff, I use Lucas carb cleaner a lot with good results. Hope you get er going.:)

Thanks for the quick reply. I tapped the carbs with the wooden handle of the hammer and she fired right up! I will get some Sea Foam and run through it. I think I might drain the gas and put fresh in before the Sea Foam though.

Glad it is working for you. besst way to prevent future problems is to ride more often. Be advised that the new E-10 gas will break down sooner that the old gas, so if you are not going to be riding anytime soon I would recommend adding a fuel additive, like Stabil.
