1100 leaks fuel out of the far left carb
19 Jul 2013 16:11 - 19 Jul 2013 16:13
Far left carb leaks fuel out the aircleaner when parked. Is this result of a stuck float or something? Any help is greatly appreciated.

That or the float level is too high. Check your oil level too, its probably going into the crankcase too. Not good to keep riding it that way

Probably results from a mal-functioning float valve (whereby fuel keeps rising), accompanied by an obstructed overflow circuit (fuel rises all the way up into the carb bore and flows rearward toward the air box and forward toward the engine).
The carbs at hand may not have an overflow circuit, in which event, there would be no such protection against fuel rising on up into the carb bore.
Good Fortune!

Be sure to give your oil a "sniff test" to see if it is contaminated with fuel. If gas is running out of the back of the carb it is very possible it ran out of the front of the carb into the cylinder. From there it would seep down past the rings into the crankcase. Ed

Got it fixed. Turned out to be a bad O-ring on the float valve. Thanks again guys for your help
