The carb expert for this would be at www.wgcarbs.com he runs a carb rebuild service out of Texas that does wonderful work.

I have some Keihin carb documentation but nothing on newer carbs so can't tell you anything by the ID marks you listed. The main thing will be two factors. FIRST, the carburetor SPACING must be the same as for the KZ900 you intend it OR you will need to learn how to modify the spacing. SECOND, there are many types of carburetor orientation such as VERTICAL as came stock on the KZ and DOWNDRAFT as on a Goldwing. Many of the newer crotch rockets have the cylinder and cylinder head laid forward for weight distribution and this causes them to require a semi-downdraft carb (not really sure if this term is technically correct) but the float/fuel bowl on this type carburetor doesn't have a horizontal gasket mating line. It is at an ANGLE. I don't think these carburetors will ever work properly on a KZ even if you got the spacing right. They just run out of gas over and over as you operate them based on my testing of these carburetors. I will attach a pic which shows the orientation of the bowls. The carb on the left is what I called a VERTICAL carb and the one on the right is what I am calling a semi-downdraft but the main thing is that the bowl orientation isn't horizontal.
