Sounds like an awesome trip! Best wishes. I do have a couple of thoughts:
1. You need a gun. Something you can wear on your body but big enough to drop a serious animal.
2. You need a rescue beacon.
3. You need to harden the busa. I would add frame rails, fork sliders, radiator/oil cooler protection. Adventure bikes are made to survive a drop, busas aren't.
4. You need to practice lifting your busa in low traction conditions. I can deadlift mine and have done it twice alone, but when I dropped it on a wet road it was a bear to lift and I'm close to 300 lbs.
5. Keep some one informed on your progress at all times. They should know when you didn't get where you are supposed to on time,
6. Plan your documentation (camera, dictation, report first thing in the morning, last thing in the evening). This might be a TV quality adventure, certainly worth a for sale DVD
7. You need some sort of tire that will work off road. I don't think sport bike tires are going to make it.
8. Plan on trashing the bike - brakes, plastic, fork seals, chain/sprockets, etc.
Remember that a part of gutting this trip out might be the realization that you are going to have to try again next year (good documentation might get you sponsorship). People who do extreme things aren't lucky, they understand their situation and make good decisions when the rest of us are in a panic!
No matter what happens, I already admire you
