2002 ktm 250 exc forks

I want to change the springs on my bike but havent done this operation since my 1977 bultaco frontera (not the most sophisticated suspension in the world). My KTM and WP manuals supplied with the bike are useless. Can anyone walk me through with the usual must-do's and must-dont's. Any help would be very welcome

Thanks

John

Hi Jeremy,
I ran a search and came up empty. Suggestions?
