there is no detail on how to adjust the idle, because this bike is FLY BY WIRE, and you can NOT adjust the idle. It's programmed in the ECU.
Fly by wire.. you have a throttle cable that then turns a position sensor. That sensor sends signals to the ecu, which in turn tells the servo motors to turn the butterflys.. the butterflys are NOT turned by the cable as they are on prior generation R6 engines. If you pull the airbox cover off, with the ignition off, and turn the throttle grip, guess what? the butterflys do not move.
thus there is no way to mechanically hold the butterflys open via idle screw. And if you DO devise some way to do that, the ecu is still telling the injectors to meter out the original amount of fuel, and the A/F mix is lean.. bad for the engine.

there is likely a better and more accurate explanation in the manual, or by someone else, but this is my quick rundown of it.
