The solid type airscrews and the long jets are the right ones for your model. Genuine Keihin jets have the star like K logo stamped. You may want to consult the overview attached. Generally speaking the chokes will be fully opened again before departure but you will need a raised idle for the first two km. Some keep the grip twisted for this, as suggested in the Owner's manual, others use the big idle adjuster which they readjust at say the second traffic light. Do not expect a good acceleration from a stop with the throttle yanked open more than halfway.
