    Will '78 GS750 carbs/assembly fit a '79 GS1000?

    I have a set of refurbished carbs (complete in rack) which I advertised for sale.
    A guy wants to know if they would physically fit a '79 GS1000?
    I don't know, perhaps someone here does?
    TIA.
    Cheers, Andy

    They will bolt up but the brass will be different. Main jet, needle clip position and the emulsion tubes are different so your buyer may need to change those around.

      Thanks for that Matt! I didn't know if they'd bolt up or not. Re the brass, yep mains, needle and emulsion will need changing.

        The VM26SS and VM28SS racks are physically the same carbs with the same spacing on the GS750 and 1000. (also fits Kawasaki Z9/1000).
        The Suzuki have both air and fuel mix screws whereas the kwaks only have either one or the other.
        The 750 carbs will work on the 1000 with just an increase of main jet.
        To convert totally to 1000 jetting a GS1000 carb rebuild kit from Keyster will do the job.

          Thanks zed! I have no idea at this point whether the prospective buyer is rebuilding a stock 1000 or something else....
          At the end of the day, it's his choice and I'm in no hurry to sell.
