    trouble with my gs550es

    i just bought a gs550es with 5600 miles on it. the bike hasnt been riden much. its a 85 and and starts right up. once the bikes starts up it starts to dump fuel out the air box. weve clean the carbs thinking it could be the floats, but after we did that it still does the same thing. need help!

    It sounds like you still have a float problem. You need to make sure the float...floats, and the needle and seat are sealing. Also, the oil should be changed since it's most likely contaminated with fuel as well.

    Sorry for the bad news.

        definitely still a float problem. Be sure to disconnect the vent lines from the carbs as well.

        If you love it, let it go. If it comes back....... You probably highsided.

          When you have the carbs apart it is important to double and triple check that the needles are free moving, same with the floats, and make sure that they actually seal. I actually sprayed a wee bit of carb cleaner thru the fuel lines so I could see it coming out the correct places. Also, is your petcock manual or vacuum operated? Either way, you should check it out and possibly repair or replace it.

          Good luck!

            It's vacuum operated, like all GS's :-) I happen to have one. Though he says the leak comes from the airbox which makes me suspicious if that's REALLY wehre the leak is coming from. Perhaps the fuel line is broken?
