Before changing jets, drill out the airscrew access and try closing that screw by a half turn. See what that does. This will give you a clue as to which way to go.

These bikes ship too lean for sea level. You could still be a bit lean at under 2k feet.

I think people at 4k elevation are pretty close with stock jetting
