Fits Piranha 125cc pit bike
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.

When modified it fits drz400e slant fcr carb
Says it fits drz400, it doesn’t fit drz400e with slant style stock Fcr carb. I made it work, When screwed all the way in it hits the float bowl drain bolt it was cheap so I ground it down (see pictures) I’ll take another one when I install carb back on bike

Don’t waste your $
The media could not be loaded. Stay with stock. You cannot get this screw to stay in a fixed position. I even put a stiffer spring on it and teflon tape on the little threads to try and keep it from moving. That helped a lot but after I went for a little rip I looked and it had turned. Keep your money

Fits Chinese made Mikuni vm22/ vm26
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.

Does not fit Nibbi pe28 air screw
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.

Will never own a carb'd bike without one again!!!
Best moto part I've ever bought. Fits my 08 Yzf250 perfectly didn't even have to remove the carb. Instead of having a happy medium setting with old style that was a pain to adjust and always guessing where it was at, the numbers and easy turn make me able to set properly every time I ride. due to major temp fluctuations living in north ga I was always in need of a tiny screw driver and guess work. Now ican get the most out of my bike. Also rode 2 hours in gnarly Rock gardens today and it never moved. Buy it, it's worth it!
