Just a piece of advice, before you spend all kinds of time and effort, and money on this, take your zx12 out and hit the top speed limiter.
See if it is something you have the balls to do, and if you really want to try to do it again.
I've been into the upper reaches of the unlimited '00 zx12's capabilities, and I can tell you the bike has bigger balls than I do. I did not have the cajones to top the bike out. I am honest.
I've heard a few guys talk of showing over 200 mph on the odo, but never a GPS or radar reading to prove their speed. Also accounting for 10% speedo error, that 200 mile indicated could be a 180 net run. Not slow, but a loooong ways from 200.
Whatever you do, make sure your mojo is with you, and all your senses are totally aligned. At those speeds one teeny, tiny mistake, or rabbit and you are dead, now matter how much equipment you have on.
At the upper reaches, I strongly advise you not to try to look at and decipher the speedo.
Get a GPS for this excercise.
