I looked in self help, and still can't find the answer...trying to readjust the rear shocks. the cans turn and I can not get the jam nut to loosen away from the adjuster plate so i can adjust them down. I did not jack up the bike, but put her up on 4x8 blocks to give me clearance to turn my wrench, but the cans just spin. I can't fit the crescent and the spanner in there at the same time to break the jam nut loose as the space is too narrow...any suggestions? Thanks. bcortani.
