You can get to them from below but it is a pain in the ars. I adjust mine from up top. Pull the windshield, inner plastic aroung gauges, unbolt the two bolts that hold the gauges to the faring stay and wiggle the gauges out of the rubber grommets. Take your bike out in the dark and adjust till it's where you need it, then take it back to the garage and button it up. If you do some night riding I would recommend that you look at installing HID, it's the best mod you can do to a busa in my opinion. If HID is not in the budget, while your in there put in a Sylvania H7 Silverstar bulb. 100% improvement for $20.
