    Mikuni carb help for identification

    Hi everyone

    I bought a set of mikuni carbs for my project.
    I can not identify them (do not know about where they come). Could someone help me to identify them? Then it would be easier for me to find boots, jets... thanks

    - holes pattern = 77 - 93 - 77
    - inside diameter = 34mm
    - outside diameter (boots side) = 42mm
    - outside diameter (airbox side) = 50mm
    - brand = mikuni

    - picture:


    thanks in advance!

    The 34 ID says it might be off a gs1000 or gs1100. Take off a fuel bowl and remove a main jet for clues (see if you can read numbers). Someone on here can confirm spacing.

      The "choke" linkage is from '80 or '81.

        Looks like the # 3 diaphragm cover is incorrect.

          That's just the metal bracket for holding the throttle cable.

          These carbs look identical to the BS32's on my 650E... obviously the 34mm measurement indicates that they are not off of a 650E though

            Those are either a 1980-81 GS1000 or GS1100 carb set. Take a picture of the other side and it may give a definitive answer. The primary difference is with the main air jets. The main air jet is pressed in and not easily replaceable. If the whole in the main air jet is 1.7mm then they are 1000 carbs. If the hole is 1.2mm then they are 1100 carbs.

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

              SUDCO still carries all the jets and replacement parts for these carbs. regardless of whether they're from a GS1000 or GS1100, the style of jets is the same.
