Vito's fits Yamaha Raptor 660 adjustable fuel air mixture screws UPGRADED BRASS 01-05

Threads don’t match “China carbs” only fits stock carburetor.

perfect fit for STOCK carbs, don't listen to negative reviewers who have the crappy Chinese knock-off carbs. This is a great product.

Fit perfectly on my 2001 Raptor 660R Stock carb Makes ajusting it a lot better!! Good quality product.

I bought these for my 2004 Raptor 660. I could never get my air fuel mixture set right with these enough to get a smooth idle due to the looseness in the threads. They are loose enough that you can move them side to side a millimetre or two. The knob on the end that is supposed to make it easier to access with your fingers is still almost impossible to reach with your fingers and there is no slot on the bottom to use a screw driver. I would not recommend these for a Raptor at least.

Good product recommended for many

Excellent product. Helps make adjusting carburetors is simple and easy

Worked for 05 Raptor 660

work flawlessly. Very easy to adjust the A/F ratio with out having to remove fender, seat gas tank ect. And it's numbered so you know how much you have turned itUPDATE: Less than a year and they already started leaking. Disappointed
