see my slightly elaborated instructions above.
Also note that the pin-bar clearance is very tight on a Busa for this type of lift. Pit Bull notes that on their web site. I have about 1/8 inch clearance between nose and bar on my '00.
Also pull the front fender off first (before lifting) if you were planning to remove that.
I insert the pin with the bar off centerline by about 20 degrees (ie, stand in front of the bike and put in the pin with the bar pointing off to the left or right of the wheel centerline by about 20 degrees so it clears the front fender), then once its in, I rotate the bar to centerline. I then rotate the base under it, slip the bar in the base slot, and then rotate the base to lift the bike.
.... hard to describe in words.
