Yep,
Just remember
GENTLY SEATED position. Your not gonna hurt anything moving the air screw around so don't worry about blowing anything up...Yet...
Move the airscrew about a 1/4 of a turn either direction and take a spin, just like getting a pair of glasses... Better or worse?...
A general rule is to try and keep your airscrew at about 1 1/2 turns out from gently seated. That way you can dial it in or out as needed for the riding conditions of the day.
The N82m Needle is the stock needle alot of KX5's came with from the factory and lot's o guys like to run with.
The next time you have the carb apart, look at the needle just under where the last clip position is.
That's where you'll find your needle # stamped into.
