Well so far you have a well rounded set of mods, adding a decent amount of power, but not to much, basicly the next things I would do would be get carbon fibre replacments for the plastics, perhaps a slightly wider rear tire for traction, depending on how youa re going to use teh bike an extended swingarm, and if you wanted all out power you could get a turbo kit, possible upgrade suspension, id also sugest a stearing damper if you are gonna be taking it up to high speeds
