    My GS dilemma

    Pretty simple really.

    It's time to clean my GS550 stock Mikuni VM22SS carbs. An old friend gave me a set of Mikuni VM24SS carbs -- probably from a Kawasaki KZ650 -- before he moved. My original carbs are dirty. The ones he gave me look like he cleaned then. His are on the top:

    Others on this forum have said the VM24SS carbs are better, and will fit & work fine. My Clymer GS550 '77/'78 manual seems to say the same thing in the "Performance" chapter (continued on next post).

    My dilemma is that I have kept the bike in stock condition since 1977 -- except for adding a seatback & rack, and an oil cooler. Should I really make the change or not? And what is the extra orifice for on the VM22SS carbs -- next to the asterisks? What does it do, and do I need it?

      Is this an award-winning Concour d'Elegance machine or a daily driver?

      If it's a show bike, your other changes will detract from it, the carbs won't matter much more.

      If it's a daily driver, why not use what allows that part of its function?

        The next question I would be looking into is whether or not the replacement carbs would fit into the existing boots that attach to the cylinder head and if the intake side will mate up to your air box.

        1982 GS450txz (former bike)
        LONG list of previous bikes not listed here.

        These aren't my words, I just arrange them

          Clean the stockers. The jetting is proven. There is no reason to stir the pot.
