I didn’t see anywhere on this thread how you identify which carbs you have. My owners manual says VM26SS. ‘76 KZ900 LTD. Mixture screws on an angle on the sides. Would be nice to see a pic of these ‘bottom’ mixture screws to help others identify these odd setups on some bikes.

Not sure if this is what you are seeking but here are 2 pics for showing differences between air screw and pilot screw within the pilot circuit. The first pic is of an air screw, note its path. An air screw allows for more or less air to premix with the fuel pulled up via the pilot jet. Turn it in to lessen air and turn it out to increase air. This exits into the carb throat below the throttle slide.

The second pic shows an pilot screw, sometimes called a fuel screw. Note its path and the differences between it and the air screw pic. The pilot screw does not have anyway to control the amount of air allowed to premix with fuel pulled up the pilot jet. Rather what ever the mix is (due to pilot jet size and pilot air jet size) to enter the carb throat on the engine side of the slide. It also has what is called a bypass located below the slide.

It is only some VM26's with the fuel screws underneath that are made up of left hand bodies.
If yours have the AIR screw on the side then just fit them as highlighted in white in the pic.
It is always the air passage diagonally opposite the air screw.

Would love to pick up a set of these if they are still available. For the life of me, I cannot figure out how to send a PM.

Do you sell air correction jets for Keihin CV34 carbs?  I saw mention of this in a thread here...

Greetings from Winnipeg, Canada. I am currently having hesitation issues with my ride and I am very interesting in purchasing these air corrector jets from you. I have had the carb pack off and on more than a dozen times trying to find the correct combination of pilot and main jet to get the hesitation ( Bog ) problem resolved with no luck. What you say in your topic regarding the extra amount of air entering the engine after installing air pods is 100% true. When accelerating past 1/4 throttle, I can hear the engine sucking in air profoundly. The hesitation seems to happen around 3000RPM in all gears. If your jets can solve this issue for me that would be great. My ride is a 1976 KZ900 Z1. I have had the top end rebuilt with .010 over on the pistons, air pods installed and 4 into 2 Jardine header pipes. I am currently running a # 120 main jet ( 2 sizes over from the factory #115 main jet ) and a 17.5 pilot jet ( 1 over from the factory size of 15 ). My carbs are Mikuni VM26SC and have been rebuilt with all new parts and the needle size is 5DL31 factory sized needle. Clip setting on the needle is in the middle position. Can you please advise on what my cost would be to have a set of 4 of these jets sent to Winnipeg, Manitoba, Canada. Postal code is R2G 2P7. Thanks so much and hope to hear from you soon regarding what your thoughts are on my hesitation issue and if your product can resolve this issue.

Hi, Kenny.
Your carbs should be VM26SS with 3 bolt tops ..( The VM26SC are Z2 750 fitment only with 2 bolt tops )
The hesitation is caused by a lean spot on the transition between the pilot jet and needle jet so it's not a pilot jet or main jet issue and only the main air jet conversion correctly rectifies the issue regardless of engine tune or exhaust fitted and without adversely affecting the fueling in other areas of the fueling curve.
With the air correctors installed you need to put ALL carb and jet settings back to stock and just increase the main jet one size up from stock.
I hope your carb rebuilt used all original MIKUNI if any brass was replaced and the pods are quality K&N etc.
Unless physically damage the original brass should be retained..
Price for jets delivered worldwide is £41.
