I've never heard of anyone putting Ninja carbs on a KZ. I might be wrong, but I thought Ninja carbs were designed to mount at a different angle than the KZ carbs.
If you've got VM26 carbs, you can get a set of VM28s that will bolt right on. You could also pick up a set of 29mm smoothbores that will bolt right on (if you've got some $$$ to spend). You could also go with BS24 carbs, with some modifications to the intake manifolds and throttle linkage.

I'm sure we'll get some other comments from other posters who are much more expert with carbs than I am, but I seriously doubt that throwing Ninja carbs on that engine (even if possible) is going to be the best solution for you. You mentioned that the Ninja carbs are "huge". Bigger is NOT always better. It's all about matching the proper size carbs with the proper size jets to the proper size intake ports to maintain optimal airflow and air/fuel mixture. Bigger carbs without the matching ports/cams/valves/exhaust can kill airflow (and performance).
How does the engine run with the current carbs? Perhaps some minor jetting changes are all you need.

I need some advice please. I have a 79 kz1000e bottom end is stock (new rings). I have kerker pipe and k&n filter. While the bike was apart (valve guide came almost completely out of head.) I re-ringed it and had the head ported and polished. The guy who did the port job says my stock carbs are to small. He has a set from a ninja 1000 and that they would really wake this bike up. Problem is they won't fit my air box. So are the carbs worth the tuning issues u get with pods or should i just get a dynojet kit for the stock carbs?
the KZ1000st is a heavy bike (600 lbs.),stick with the stock carbs,she will be a dog at lower rpm otherwise

I'm thinking this guy is just hypeing up his work... like otakar says - he probably just ported (mildly) & polished the head, which won't require larger carbs!

I know he didn't change the valves. And yes the port job is mild, but more than just smoothing out the casting. The reason he claims I should put the other carbs on is because the early Z1's (900's) had bigger and better carbs and more performance. He claims when they added emissions stuff to the bikes they "choked" the larger motors (1000's), and since the old smooth bores cost a fortune these days the later carbs are cheaper and an up grade from the stock carb.(not better than the smooth bores, just better than the vm's) Supposedly he's done this before with great results. They cam from a zx1000a (maybe that's not a ninja.)
the '79-'80 KZ1000's came with VM28 Mikunis,same size as the early Z1's.
your "mechanic" is blowing smoke,the zx carbs are a different spacing and will not work

Hey, I'm not putting down the guy's work... and yes, the early 900's came with 28mm VM's and pulled strong as hell with them. If you can find a set, get them - but first try to tune the set you've got... I think you'll be surprised!I guess it's stock carbs then, probably a jet kit 2.
Good Luck
