Few things needed to get the idle circuit correct.
1. Correct float level (slightly lower than stock)
2. Manually set the idle screw into position so that the slide is only just a few mm open. You can either do this visually through the carb throat, or audibly by listening for when the slide bottoms out and then turning the idle screw in until the sound just changes.
3. Set the air screw at 1.5 turns
4. Change pilot jets until you find the one that allows the bike to idle once up to temp with all as above. If the bike idles well but still runs too rich at 1/8th throttle, and leaning the air screw doesn't help/deteriorates the idle and starting, change the needle diameter to one richer and start over. (or vice versa if lean).
