The slickest way to clutchless upshift on strong acceleration is to apply upward pressure to the shift lever while running up the revs, to shift simply blip the throttle off/on slightly and quickly. The first time I ever tried this I was pleasantly surprised by a better, faster, and easier way to upshift. Each bike is a little different but the Busa responds well to this.
Don't forget to try this method for a smooth transition when you power the front end off the ground and take it on into second gear. This is such a quick and smooth way to shift that you can make the shift to second and land the front wheel gently back to the pavement.
