definitely the Pro Circuit Platinum pipe and possibly one size leaner (smaller number) main jet. Of course only after your air box intake was enlarged with the snorkel taken off. The high tension reeds mentioned are made by Carbon Tech. I have their low tension reeds since I needed more low end since I ride mostly on the street. But you can get more out of the stock reeds just by removing the reed limiters. Or buy cheaper two stage fiberglass reeds (by Boyesen).
