The only difficulty dismantling modern fork legs is to hold the damper tube while undoing the bolt that retains it in the bottom of the fork lower tube. To make this easy I welded a 30mm nut to a section of tube see diagram. Tube diameter doesn’t matter much, mine is made from a piece of 25mm outside diameter tube. Insert the tube, nut first into the upper stanchion (top tube) and fit it into the socket at the top of the damper tube to stop it from turning while undoing the retaining bolt at the bottom of the forks.
This tool fitted both my Yamaha and Kawasaki dirt bikes as well so must be pretty standard for moderns. Never had this problem with my Meridens, just loosen the bolt at the bottom of the forks before you remove the top nuts and springs.
