No Carb Kits for 79' KZ650D2

The kits came, nice and shinny, despite being kits marked for 77-78 it has most of the parts that I needed, I thought that the only thing that was going to happen is that I would have a couple of parts left over for the carburetor model of prior year KZs. I was wrong!
Carb Kits:
- The bowl gasket is the wrong one, it has one missing big hole and it can't be used.
Accelerator Pump kit:
- The square diaphragm instead of being a thick membrane it is composed of two thinner ones, similar to the petcock diaphragm. It will probably work OK but I will kip the old one just in case.
- It comes with a set of:
- 16038-016 "0" RING,MAIN JET COV
- 92037-1123 CLAMP,SPRING,CHECK VL
- 13042-1004 WEIGHT,PUMP,CHECK VLV
- 92140-1003 BALL,STEEL,CHECK VALV
I check again to see if someone sells a proper carb kit and all the kits seems to be the same, with more or less jets but all of them with the wrong gaskets.
I would have expected a proper kit coming form K&L and sold by Z1exterprises. The good thing is that at least these kits are not necessary very often.

As you've already discovered when getting float bowl gaskets, you need to make sure to get the correct ones as there are at least 2 different shapes for the KZ650 VM24s. When I rebuilt my carbs, I only replaced the gaskets & rubber stuff. The brass parts were fine.

Just an FYI, the small o-ring fits onto the pump nozzle base at the underside of the carb body. You could get a metric nitrile or viton o-ring kit for the other 3 nozzles. Or maybe Z1Ent has the size - they do list individual o-rings.... the kit might be cheaper, though.

It's true what you say about the rubber parts, in this case the previous owner replaced the main jets and the float needles were really worn out an edge at the needle tip could be seen and felt.
There aren't many shapes for a 1979 D2 bowl, the gaskets included are as the kit label says for a 77-78 model, but Z1enterprises also sells those same kits for a D2 model, and they should include the proper gaskets.
If I have to rebuild them again I will only need the o-rings and may be gaskets, for this one I needed a kit and what is sold for the D2 model everywhere is not a the right kit.
About my comment on the accelerator pump, it is because the kit includes components (the listed) that should be part of the carb kit as those are part of the bowls and not part of the accelerator pump.

I think the suppliers have already decided what should be in the kits. They've been doing them that way for years & years. :laugh:murquiza wrote: ....

For example all the 22-28mm mikuni carbs use the same gasket from Kawasaki, and that is not that difficult to duplicate it seems to me, but no, they can't form a simple piece of paper to include the correct holes?
Yes even though 77 and 78 didn't use the pumps and 79 and up did, all the Kawasaki factory gaskets had the hole so they could work on either style carb.
Not aftermarket though, this hole is impossible to reproduce. Gasket junk? What are your odds on the remainder of the parts? :sick:
321,000 miles on KZ's that I can remember. Not going to see any more.

Carbs with pump are "special". As you can see the pump's bowl has an extra hole, so even including gaskets with the missing big whole is not enough to address for the difference. The solution is so simple, every bike has 4 carbs, so build a freaking kit with the right part for all the carbs.

My solution for now is to buy the right gaskets and next time I will not throw away the old ones before getting the new ones. :sick:
