Those are not the jets, the first pic looks to be a choke fuel inlet, and the seconds look to be idle circuit inlets. I don't know why one sits up higher than the other, but I'll tell you what I do know...
Take a look at your second pics. Put your cursor in the middle of the red circle to the right. Now move your cursor about 2 inches downward and to the left (8 o'clock). Now your cursor should be pointing at a screw, one of four which holds the bowl onto the body of the carb.
To get to the jet, you would remove the carbs from the motor, turn them upside down, and remove the four screws holding the bowl on. If they stick, lightly tap them with the screwdriver. Do not use a great deal of force on any carb components. The jet will be the brass screw with the hole in the middle. Do not stick anything in the hole if at all possible. To clean, get a can of carb cleaner, attach the little red hose to the nozzle, and press the tube against the hole in the jet to clear it.
Before you go through all this, I would suggest you carefully check the following, because the bike is really too new to have dirt or old gas problems..
If there is a gas tap, make sure it is set appropriately for the amount of gas in the tank (Needs to be on RES if there isn't much gas in the tank).
Check to be sure all vacuum lines are in place, and none of them are kinked.
