## Customer Reviews

### ⭐⭐⭐⭐⭐ Mixture screw
*by D***B on April 1, 2025*

Nice mixture screw fast shipping..very pleased.

### ⭐⭐⭐⭐⭐ Fits Piranha 125cc pit bike
*by J***S on October 26, 2024*

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
*by L***I on August 26, 2020*

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
