    Float pin removal

    Cleaning the carbs on my 80 GS1100L, I see the float pin is peened on the end to keep it in place. Is this necesary or does the bowl prevent it from coming out?

    The float bowl seems to fit fairly tightly beside the pin ears...I noticed that my pins only came out one way, with a peaned mushroom on one end. I don't think that the pin could slide sideways enough to un-support the float on one side.

      The bowl has a "ridge" that keeps the pin in place. On one of my carbs the float pin got slightly bent and I couldn't place it back in the posts so I just cut a piece of wire that matched the size of the pin and stuck it in there. Staying in there pretty well.

        I was given a tip by Sharpy to get a mate to hold a flat blade against the post the float pin goes through while you tap them out as they can be quite a tight fit. This stops the post breaking off, which means a new carb.

        I had to do that with one of mine, whereas the other one came out with no force whatsoever.

          The pin is not peened, it's flared on one end. To remove the pin I suggest supporting the post to avoid snapping it off.

            I use the same method, Ed. On my 650...the float pins were knurled and had no "nail head" like you show in your pic. Same removal process applies.

              ED the socket is a great idea.. I was also thinking that maybe a small brass rod cut to just snuggly go between the posts as well would help supprot the top one as well when the tapping begins.

                chuck, there is no reason to support the other post since the pin is not held on that side - it will just slide though.

                  What if they are all corroded and crusty when you try to get them out? then wouldnt some extra be prudent?
