Congratulations on a great track weapon. The 750 is revered by many as the best track bike ever built. It's like a 600 on steriods. Still have to keep her cranked up to get HP though. Not like your busa where you have grunt throughout the RPM range.
Mirrors! There is a little trick I learned that makes mirror removal a quick easy chore. The blinker wire from the mirror runs between the plastic fairing and the fairing stay. The first time you remove the mirrors you will be forced to remove not only the two nuts that hold the mirror in place but the rubber gromlets that hold the windscreen in place so you can seperate the plastic from the metal fairing stay enough to pull the electrical connector located at the end of the blinker wire through. Follow the blinker wire to the connector which is just behind the guage cluster. Lift the little clip on the connector and pull the connector apart.
Once the mirror is removed, carefully remove the little rubber strip that sits between the plastic fairing and fairing stay at the mirror mount. With a sharp knife or razor blade make a hole in the center of the rubber mount where the fairing hole is located large enough to poke the wire connector from the mirror through. Now you have a clear hole to run the blinker wire through without removing the windscreen gromlets in the future. Makes the task simple, quick and easy as removing the two mirror nuts and un-snapping the wire connector in the future.
However, be sure to have blockoff plates to install for track use. Vortex makes some really fancy ones for around 30 bucks I think. I use the bases off of mirrors that have been crashed and broken. They don't look as nice but do the job just the same. If you don't have block off plates use a zip tie through the holes or you will loose the rubber strip between the plastic and fairing stay.
Note: Apply a little never sieze to the mirror nuts and don't over torque them or you may regret it. If the nut is over tightened it may spin the stud in the mirror base making it almost impossible to get the mirror off without damaging the stud and you cannot buy a new stud.
Have fun with that beast and take lots of photos when you go to Barber so we can watch you give the "Team Gixxer" crew a spankin!
