If you get the most aerodynamic flip-flops, combine them with the lightest shorts you can find, and a very form fitting tank top, then top it off with the coolest shades, you should be able to hit 200 no problem.
weight savings will increase top speed. Take off your master, rotors, brake lines, levers, battery, clutch cover, rear sets, etc.
Maybe you could think of the gearing, dropping a tooth in the rear generally highers top end at a sacrifice of accell, like wise would adding a tooth on the front.
