    78 VM26SS carbs on 78 gs550... Is it possible?

    Searched and can't find a definitive answer so here I am.

    I am starting to work on the engine of my 78 gs550 and need to replace the carbs.

    I have the chance to get a complete set of VM26SS carbs pretty cheap ($40) but not sure if they can be made to work since the bike came with VM22SS but i had them in my truck to take to have them ultrasonically cleaned and my truck was broken into so now I have to replace them. I know it would require a lot of needle changing at least but would the effort be worth it. I am having a hard time finding any reasonably priced VM22SS carbs so hoping I can get this to work.

    Thanks in advance for any help.

      You're in for a boat load of fun.

      1998 Honda ST1100 (Daily long distance rider)
      1982 GS850GLZ (Daily rider when the weather is crap)

      Darn, with so many daily riders it's hard to decide which one to jump on next.

        they wont physically fit. inlet boots are too small and carb spacing is different

        Just remember, an opinion without 3.14 is just an onion!

          Sounds like it's probably a bad idea... I will keep hunting for the right carbs.

          Thanks for the info.

            Even if they DID fit, throttle response would be somewhat ... lacking.

            You have to be a bit careful as it is with the VM carbs, but with the larger throats,
            you would REALLY mess up the air flow if you opened the throttle suddenly.
