"Its pretty easy with the right tools."
::008::
If the budget allows:
Motion Pro - Motion Pro Damping Rod Bleed Tool
RaceTech - Fork Spring Compressor (Portable)
Motion Pro - Fork Oil Level Tool
Knipex - 8603250 10-Inch Pliers Wrench
Traxxon Dynamics is good one stop shopping for fork service tools.
Traxxon Dynamics - Fork Service Tool Kit, Inverted Forks
Traxxon Dynamics - Fork Spring Compressor Kit
I believe the minimum you will need is Traxxon Fork Spring Compressor kit (or equivalent), assuming you do not wish to change the fork fluid while you are doing the springs. I highly recommend: the Knipex pliers (I have the 6, 7 and 10 inch) since they leave minimal "scars" on the work surface, and the RaceTech tool.
YouTube has many videos on servicing forks.
