Welp, perhaps you can PM him, b/c what he GOT were airscrews. Ive seen them with my own two eyes
ORRR you could simply get them from Z1...

Yes i see that it says "Unique to the Smoothbores" But the OEM number says VM26-28
Maybe I haven't been clear here...
The VM carbs have two adjustment screws: the pilot AIR screw (as shown in your link) and the pilot FUEL screw. The air screw has a blunt tip so no worry about them breaking off. The pilot fuel screw on the other hand have a very small and sharp tip, so they break off all the time. Again, I don't think Suzuki sells the pilot fuel screws and if they do, they don't seem to be listed in the parts diagrams. Z1 does not seem to sell them either except for in the GS750 VM carb rebuild kits.
