It is in the low (idle mixture adjustment) and mid-range (needle height), but the top end (Main Jet) is on the rich side with a stock airbox and exhaust.
The normal set-up for a stock engine is 2.5 turns out on the Idle Mixture Screws with the stock Pilot Jet, 1 or 2 washers under the needle, and possibly a 1-step leaner Main Jet.
