Just a few ideas. Looking at your profile, I would try putting the bottom of your helmet down on the airbox, supported by a hunk of rubber. If your fairing is cut too high, cut it down in front for a good view of the horizon. Also, looks like you could make more forward reaching handlebars to get your arms forward and down. Make a small gas tank and put it in the seat pod behind you. Getting your head down a couple of inches will gain a few mph or more. Put your rear sets as far back as allowed (6" from rear axle at BUB, staying in M class). This is not a road race.
