Turn up the idle. Can't hurt it.
Turn the air screw. Can't hurt anything with that either.
I remember when I had my bike idle, then I accidentally kicked it in gear and the whiskey idle ride was on!!! Luckily, got it shut down before I was killed. So now its no idle for me too so I am in complete control.

Now... my '18 KTM 150 XC-W.... got home with it from the dealer and it ran LIKE CRAP. Both pilot and main jets were clogged with white powdery stuff and the fuel line from tank to carb was shedding black dust into the carb. Took care of both of those, flushed the tank, checked everything else (sand in the air box, for instance, but the boot was nice and clean so it probably just blew in from sitting outside in the nasty eastern CO wind). Point being, I just never trust a dealer. After I cleaned everything (re-jetted, actually since it had stock jetting which I knew was going to be 2-3 steps rich), it runs good.
Today, with an RK Tech head and other goodies, it'll idle for as long as it takes me to go inside and put my contact lenses on, but if I do that, I need to sit there and give it a few jolts of throttle to clean it up before I take off. That's stretching it, though...
My KX 125 idles just long enough for me to put my goggles on. The GasGas TXT will idle for as long as you want, but burbles a little when you wake it up.
You know when you are an old school two stroke guy...You still check for the fuel on your EFI 450
Old geezers think it's still 1970. My katoom will idle for long enough and is jetted great.
Clean pilot jet, main jet and emulsion tube.
Warm it up and run it thru the gears wot
Turn up your idle screw a turn and play with the idle mixture screw to get the highest idle, then 1/2 turn towards rich. If your idle mixture screw is on the cyl side of the slide its a fuel screw so go ccw, if the screw is on the airbox side of the slide its an airscrew, so go cw. (That's true for most carbs, but you need to know if its an A.S or F.S)
and if you have zero compression ..... oh fuck it, take to the dealer
Oh, and even if my 2 strokes WOULD idle for more then 10 seconds, I wouldn't let them.
And if the bikes gunna sit for more then a month, drain the carb.
