Looks like stock setting is 1.5-turns out on mixture screws.
All over the place because you keep on adjusting idle-screw. Leave that alone and learn to use choke lever.
1. Cold start - 3/4 to full choke to start. If idle too slow, increase choke. If idle too fast, decrease choke. No change in idle-speed adjuster necessary.
2. Once started, adjust choke-lever for 3-4k RPM. If idle too fast, decrease choke. If idle too slow, increase choke. No adjustments to idle-speed necessary. Start your ride
3. In 5-10 min, if you stop, reduce choke again to lower idle-speed to 2-3k RPMs. If idle too high, decrease choke. If idle too slow, increase choke. No adjustment necessary on idle-speed screw.
4. 10-15 min, turn choke completely off after bike’s warmed up.
That’s it! Never ever need to adjust idle-speed knob. It’s all done conveniently and quickly with choke lever.
