I am posting some photos of a simple tool I made to compress my GL650 fork springs after changing the fork seals. I cut this piece of scrap wood to match the config. of the fork cap air valve. I found that wearing a thick leather glove was just not good enough for my soft "white collar" hands, and by creating this "tool" I could spread the force across my palm that I was applying to the fork cap. It gave me more control to easily line up the fork cap threads and get them rotated sufficiently to stop squeezing the fork springs. It worked for me.
