    1980 GS550L Carb Leak

    It appears that my carb floats have soaked up quite a bit of ethanol. Does anyone know where I can find brass floats for this bike? Or have a possible repair for floats that have soaked up ethanol and are causing a leak?

    Do floats looked deformed? Or feel heavy? Can you tell if gas is inside the floats?

    I have not heard of this before, but then again, I am not that much of a gear head.

    Have heard of E fuel causing problems with fuel system rubber parts.
    Can anyone say if it causes problems with our carb floats...?

      The ethanol probably adds a nice sugary coating to floats helping them stay buoyant : But I wonder about some carb cleaner solutions.

        I don't think that's actually a thing.

          Can't even begin to count how many sets of carbs I have worked on over the years and have never seen floats that appeared to have "soaked up some ethanol".

          And please explain how that would "cause a leak". Where is the leak? What is leaking?

            Carb rebuild tutorial linked in my signature. Check the Newbie Mistakes thread too. Sounds like a bike in need of maintenance.
