Flooring at idle kills engine?

When my bike is at idle, if i give it full throttle really quickly it will stall. Does this mean the mixture is too rich? If I lessen the mixture it idles kind of sporadically. Right now it idles at about 1800-2000 rpm. Just wondering, what do your idle rpms usually stay around?

You've got an air / fuel issue, and your idle sounds about 1000rpm too high. Set the idle as low as you can without the engine stalling and then shut the engine off. Start by slowly (and gently) turning the air / fuel screw fully clockwise while counting the number of turns (so you can put it back). Turn the screw out 1.5 turns and see if the idle got worse or better. Ideally, you should be able to rapidly open the throttle without the engine stalling.

The screw should be turned a maximum of two turns out. If it requires more than that, try moving the clip in the slider one notch.

yes that is normal behavior you can adjust some of it out do what weld suggested, the lifans like to idle at what you have yours set at, and lower will make the bog way more noticeable.
