hey spud the reason people have issues with fork caps, is because they dont put their THINKING CAPS on before removing them! wink wink...
you HAVE TO make positively sure that you loosen the top pinch clamp bolts on both sides and sometimes even wedge delicately a flathead screwdriver in the slot to open up the clamp a bit to where you can easily and softly unscrew the caps, same for tightening....
if your forks are stock youlll be amazed when you unscrew those caps off, you actually have negative "preload" on the springs, in other words they are loose in there, if the springs are well used a little shimiing or fork spacer under the cap and between the spring works to eliminate this issue
just thought this might help a bit
