Sam,
No secret that I know of other than removing the exhaust or turning it enough to get to the bolt. You'll need a finned exhaust nut wrench, which is considered a special tool or in Monte's camp; a Fugowe Club. Hope I got the spelling right Monte. They can be purchased from a lot of different vendors.
You'll need to loosen the finned exhaust nut, rear muffler attachment at the frame underside, header bracket attached to the motor mount and the crossover. If your exhaust system isn't frozen together you should be able to just swing it outwards enough to access the sidestand screw. Chances are the crossover(s) will give you the most irritation. If so, you may want to apply penetrating fluid at the exhaust slide fittings to loosen things up.
Damn side stands and center stands on these bikes are the weak link. Don't expect a lot of improvement in the event the sidestand ears or the frame tab is worn.
