Just curious if a stock 400ex carb would work well on a z400. My z400 has a 435cc Athena kit with hot cams intake cam & stock exhaust cam, Muzzy full exhaust system, no air box lid. I would appreciate any info.

Not really, your best choice would be an FCR off a yfz450.

If you have an old CV style carb with a vacuum actuated slide, the 400ex carb will be a big improvement, along with the 400ex intake boot. Both are pretty popular mods that you can find info and pictures for on Google.
