The CJR Brass air screw replaces the factory plastic phillips head screw with a brass thumb style adjustment. The stock screw degrades over time and requires a tool to be adjusted. Brass is more durable and precise than plastic, ensuring that the part will not fail like the stock part. Adjustment is also much easier by simply turning the knob by hand! Fits stock and Koso throttle bodies.
They sent me the wrong air screw. The one I received was less than half the size and didn’t fit the thread pattern

They work awesome
I have a 2022 Honda grom and a 2023 I’ve been looking for new ways to make them run better and these make it easy to adjust only reason I gave it 4 stars is I think I was playing with it to much and it fell out on the road

Well made
Fit and finish are great. Nice for quick tool-less adjustments.

Like it lots for easy adjustments, no need for screwdriver and will out last stock.
