Here is my pretty new carbs I got off e-bay- and the seller described them like this:

"made for kz's in the 70's which are 1976 kz 900 LTD carbs......stage "3" jet kit......complete rebuild and glass blasted......nice gaskets......20 mile test run was performed on these carbs. these carbs are ready to burn some tires......every part on these carbs. where cleaned and put back together like factory"

I had to trim the side covers for the chopper air cleaner- but it looks super sharp!
