It's a great idea, but for me Kawasaki just doesn't make a great product. They suck to work on, and use low grade components and the mono-block design, just blows!
Otherwise they look ok.
I'd rather wait for Suzuki to make their new Busa. I love the one I have and Turbo and intercooled thanks to Stedman, well is pure insanity at its finest!
With a little effort you can build your Busa to be all of that Kawi and more! It's not that hard.
