In some cases if you leave one side tight and just barely loosen one side, you can slide the fork tube back into the position you want. Then move on to the other side. A little WD-40 never hurts either. This doesn't always work but if you don't have a front steering neck style stand, its worth a try.
Just make sure the bike is stable before you go pulling on the forks...don't want a tip over.

Another way if you don't have a front stand is to have your Busa on the kickstand. Loosen the right side fork tube, then have a good strong friend grab the handlebars and pull up. Slide/work the fork tube down. It does work. Then do the other side.
