    think there are two types -
    water heated and electric heated - do you have any preference ??
    Guessing the loom or water pipes will b different depending on which you fit.
    Early bikes were water heated and later ones had the lectric gubbins under each carb.

    If you mean the ones that go into the bottom of the float bowls on the later ones then , IIRC, they are fuel cutoff solenoids.

    All ZRX carbs, from 1100 to the later 1200 ahve a water heating circuit to prevent carb icing.

    As said above the later 1200s have a fuel shut off solenoid attached to the float bowls.

    It should be noted that the jets and needles are different from the 1100s to the 12s, but if you are going to rejet to suit your setup, then this should'nt be an issue

    are the needles just different heights or totally different???
    dont suppose you know what the standard 12 jets are by chance, have 1100 carbs that will be fitted to a 12 motor

    IIRC The needles are different to the 1100, but I don't know what the difference is, the jets on a 12 are different from the 11, and also for the outer and inner two carbs.
    If you are rejetting for a full system, or other mods, you will be changing all this anyway so it won't matter

    Unless the carbs have the fuel cut off solenoids then then cylinders 1&4 are 95 and cylinders 2&3 are 98
