Possibly an aero attachment to your back to get the air flow behind you less turbulent, a boat tail that was attached to your back in your tuck.

I am designing a simple boat tail trunk as every motorcycle needs some kind of luggage. I may then also play with an aero back pack to get the air from the base of the helmet down to the front of the trunk. I also have a concept of a cloth fairing which you put on over your riding jacket like a vest and the back would be a flexible sock that could be stretched back over the tail of the trunk to create a smooth fabric skin. I would eventually like to do something behind the legs like a land speed bike but might just hold off on that until I can get the CBR125R and make that into my all out competition machine.
.
I can bring some kitty litter to add mass in the trunk if I get any practice time on the track, which I doubt. Tuning on the track would be the best way to find out if it is feasible or not. You obviously wouldn't want to add mass if it would then require a downshift or brakes anywhere. But barring those handling and power to weight caveats , more mass would mean more energy storage during the pulse. Better and smoother utilization of high throttle angles and a longer coast to make it all much easier to administer. Lower frequency. I'll have to get on google earth to look at the track to see how tight or hilly it is. If there is a hairpin or chicane that is tighter than 50 mph then you would not want to add any mass.
