Confirming what carbs, '80 kz650

1980 kz650 f1,
So I've got the carbs off the bike and the bowles off the carbs.
I have a single fuel inlet, single pump on the #2 carb bowl WITHOUT the second pump diaphragm and cap.
From what I've read that means that I have the vm28's, sound right?

I need a bowl gasket and one of the impossibly tiny wire clips for the accelerator pump check valve.
Looking for gaskets and rebuild kits I see several for '77-79 kz650 but nothing for the '80 f1.

Anybody got a line on those parts?

I'm also still looking for a service manual to download for the 1980 kz650.

No more of that talk or I'll put the leeches on you, understand?

Looks like I'll need to wait until I get home and in front of a computer, jetsrus.com and a smartphone don't mix well, lol.
Looks like they do list 2 part numbers for the bowl gasket.

Post a picture of your carbs that shows the whole carb from the back side. If you do that I can tell you if they are stock KZ650 Mikuni VM24SS or Mikuni VM22SS carbs. If they are neither of those someone else may be able to tell you exactly which carbs you have. Ed

I'll take some when I get home, I took pictures of the bowls but not the bodies.


The clips on this page looks like what I'm after!

If that's all you need, why not make your own out of a spring from a ball point pen?

Already have a pen apart on the bench. :)

Also need a bowl gasket and I'm waiting for my megaphone baffle so I can figure out jets and needle height.
The needle is marked 5cl30 and is adjusted with shims I'm guessing?

Kawasaki disabled the vacuum sensor on the VM24s after 1978 or 79.
My 81 650-csr w VM24s has the accelerator pump w triangular flange but it doesn't have the vacuum sensor stuff.

A pen spring may work. I bought a couple of stainless springs at the hardware store (3$) of the correct diameter and snipped of a link and bent them into the shape of the clip. R
