I discovered a great way to reinstall the spring, a while back (wear safety glasses and gloves for this stunt). Swing the side stand in the down position and hook the spring at the frame end. Take a large Phillips screwdriver and line up one of the tip grooves under the hook on the stand. Loop the spring on the shaft of the screwdriver. Using both hands, push straight down on the handle of the screw driver. Everything gets really tight but as soon as the shaft gets below the hook, the spring shoots up the screwdriver shank and snaps into place. Takes some practice, but works well.
