Fair the front wheel, extend the fairing as far back as you can to comfortably enter/exit the bike and make a boat tail/backrest for you. Extending the windshield would increase fronatl area but at that rake it may not be that big of a deal, dropping the seat would keep frontal area the same and get you out of the air flow. Keeping tucked behind the windshield would do the same but not be as comfortable for you to ride long distances. Im no motorbike expert but I think that those are the pieces to drop aero drag on a bike. Unless you want to make doors and leave the bottom open for your feet.
