I'll be honest and say that I've never put an airbox on a KZ1000, but I have the parts and am planning to do it. My impression is that it just rests on the little stay bracket and is not bolted to anything but the carbs. My KZ650 box had mounting tabs and bolts, but the KZ1000 does not have any visible mount points, and the diagram for the kz900 looks pretty similar.

Thank you. Any comments on the filter material in the drain cap?
Yup. Just sits there. That stay bracket is attached to the frame. Basically just a bigger space for the airbox to rest. If you want to get technical, the airbox IS secured to the bike, by having it clamped to the silencer, which in turn is attached to the frame.
Was you discover the joys of installing a carburetor rack with the airbox installed, you'll understand that there's no where for it to go.
Fairly certain mine has no filter material. That was probably to keep the critters out.
This is the best photo I have of that stay bracket. Honestly, probably could do without if it's missing.
