Default Air screw adjustment

Hi everyone. I have 98 warrior that has a screwed up air screw. Does anybody know the stock adjustment, bc when you are really moving in 6th gear, it cuts out and almost skips. it also has an aftermarket pipe (glasspack), will that affect the air screw or the fuel screw?

that will effect the fuel screw adjustment from 0-1/4 throttle. I would try around 2 1/2 turns out.
