I have 125cc pit bike with stock carb and it works. My fuel/air mixture screw fell off while riding and couldn’t find it. Tried this one and it works. U do have to grind of a bit for it fit but it fits. Either that or cut the screw to fit. Hope this helps anyone in similar situation.

These fit the Chinese made Mikuni vm22/ vm26 replica carburetors perfectly! They have the same thread size as the stock screw and screw hole does. The o-ring, washers, and spring work well to keep the screw sealed and tight enough to keep it in place, it doesn't back out or loose adjustment. The tapered end is a little different than the stock screw but seals into the carburetor body as it should. Cheap and easy way to adjust air/ fuel mixture!I used this on a Ssr125 with the Chinese Mikuni vm22.

I tried to install this on my Kayo T4, which has a nibbi PE 28 carb. Threads didn't match and the tip was very different (the air screw on the Kayo was blunt, whereas this one is a needle as pictured). 3 stars because it may be a totally good product, it seems like it would be, but it doesn't work for my bike. So, I don't know how well it functions on a bike that it fits.
