Hello carburation experts. I put a JD jet kit/3x3 mod in my 2017 S a couple months ago and everything has been great - except when I am working the bike over technical stuff, slipping the clutch and cutting the throttle when I pull the clutch in . For some reason I have not been able to determine, the bike stalls. It also stalls if I am idling with the clutch all the way in going downhill. It's worth noting, that under ordinary riding conditions (on the street) there are no issues - no stalling. The bike idles smoothly, the power at low rpms is strong and smooth and it runs smoothly all the way up to pinning the throttle (in every gear). I have adjusted the fuel screw in increments from lean to rich and this seems to make no difference. I have also adjusted the idle speed using the cable stop screw so the bike idles at a faster speed, but this also makes no difference.

I'm a crap rider and riding over roots and rocks is hard as it is, but doubly so when the bike keeps dying every time I slip the clutch. Any thoughts you have would be much appreciated.

Bump your idle up (1700 to 1800rpm) using the idle adjustment (not the cable), retweek and peak idle mixture.  You want a little slack in the throttle cable.  Go ride.

Bypass the kickstand safety switch. Kickstand could be bouncing or you could be bumping it with your boot.

I'm a noob mechanic too! How do I adjust the idle not using the cable?

Ok, I'll definitely check that out. I did have it die once because there was fine gravel jammed in the stand that kept it from traveling all the way up.

There is a plastic knob below the carb, CW increase idle, CCW to decrease. 

To peak the idle, adjust the fuel mixture screw (bottom of carb) for a crisp exhaust sound.  Solid bop, not buuh.  Should not blip stall, nor hanging idle.
