Thankyou all for your input and Merry Christmas and Happy New year to all members.

I have a 1980 Kawasaki KZ750 Ltd. I bought new. I recently managed to get it out of my garage after 28 years and put it on the road again (2010). I feel like a kid all over again. Since I have acquired 3 78 KZ1000 Ltd, 1 1981 KZ1000 Ltd, and another 1980 KZ750 Ltd. Love the LTD's.

If you are trying to find a set of smoothbores look for the brass bead showing in the rectangle on the carb as shown in the red circle below. Ed

I have used just about every carb every mod and every mod exept frame mods for speed easy to just lose some of your own weight isnt it. I must have 13 bikes 50 sets of carbs and a little common sense. Oh and an empty bottle of wine cheers

I REALLY don't get this fascination with people and 29s, they are expensive, work a little better offer an extra millimeter of venturi size, and are expensive OLD tech, if you insist on paying $700+ on a set of carbs, get something modern, adapt a set off a gsxr, or a newer ninja, buy actual NEW carbs or just do an EFI swap and forget tuning.

You have 3 basic setups for 29s, kz, suzuki gs, and honda cb750; z1enterprises had/has a page on identifying the differences.

my bikes; 80kz1000(project), 77 gl1000, 74 h2 (project)
Past; 78 kz1000, 83 kz550

I agree with you but I like running the air box. Is it possible to run the air box with newer carbs?

Yes.

You might have to make the openings larger. I'd like to have some nice flat slides.
