First of all - do it! Riding and racing is fun. Last year I rode to El Mirage, raced, and rode home.
What you want to do is line up some support for when you're at Bonneville. You'll need a place to stay, plan a hotel early or shack up with friends at the bend in the road. You won't be able to pack a tent with you and ride.
Also, you will need some sort of mechanical support out there. You need basic tools, shade, supplies (water, clothes, food). For your pits, you'll need to put a tarp down and you must have shade.
Truthfully, anybody at Bonneville will loan or give you all this stuff - you just have to ask. Talk to folks that are going and get started planning.
Lastly, you probably won't run 200. Sorry to burst your bubble but stock Busas don't go 200. A stock Busa will run anywhere from 150-185 and change. Basic mods will get you a little more. Big mods will get you a little more (maybe). The Salt gives what it gives.
For BUB, it is not as busy as Speedweek and the weather is different so camping (for free) is a little sketchy. Hotels will be easier to come by. Since there's fewer attendees, the vendors at the Salt are fewer (the food trailer for instance might not be there all days).
For your bike, depending on how much long distance riding you do, I would say get bar risers, a big tank bag, a big backpack, and that's about all you need. (I also have a CamelBack that I use). Of course, you will have to take all this stuff off when you get there.
Don't forget the bike will need to be race prepped which means safety wire, fuel cutoff lanyard, leathers, all that stuff. Also, I'm not sure if BUB did it but SCTA just went to a race tire rule for classes where the record is over 200mph which is every class a Busa races in. So you'll need race tires if the new SCTA rule applies (it probably doesn't but you should check).
any more questions, feel free to email as I don't check here too often.
