On the '06 I had to remove the forks due to the preload adjuster. I suppose you could do it once the wheel and fender was off, but it just seemed easier. I removed the fork leg after loosening the cap, unscrewed the cap, broke loose the retaining nut on the rod, used a bent coat hangar to hold the rod, removed the old spring, replaced the oil, inserted the new spring, insured 10mm of thread showing above the nut, attached the cap, tightened the nut inserted the fork cap and reinstalled the fork. Easy work overall, just time consuming and of course dealing with how to get the front end in the air. I have a steering head stand, so it's easy.
