SHOCK REMOVAL AND INSTALLATION– The shocks are fitted with special length spacers to maintain correct alignment between the frame and the swingarm. If the shocks are removed for service or repair, they must be installed in the correct position. Refer to the diagram on the next page for spacer positioning and layout. NOTE: Misalignment between the mounts on the frame and the mounts on the swingarm can cause binding between the shock shaft and shaft bushing. Misalignment of more than 1/4 inch can cause the shocks to bind up and not function properly. If this binding occurs, the shocks will feel overly stiff and harsh. Follow the procedures below to check for misalignment when installing the shocks. NOTE: The shock bushings are designed to have a certain side-to-side “float” to keep them from binding. As a result, do not grind or file the inner or outer edges of the bushings to make them narrower. The amount of “float” in the bushing set is necessary to ensure smooth operation of the damper assembly. If the shock eyes are tightened metal-to-metal (the outer faces of the eyes to the flanges or washers), this will lead to a harsh, stiff or choppy ride and premature seal leakage or damage to the shafts. MULTI-RATE SPRINGS Depending on each application, single or dual-rate springs are available. Dual-rate springs are just that– a spring set with two separate rates. This is done with a short spring stacked on a longer spring. As both springs compress they produce a soft, or initial, rate. The spring set will maintain this initial rate until the short spring stops compressing. At that point, the spring rate “crosses over” to the stiffer, or final, rate. This multi-rate system allows a soft initial rate for comfort on small bumps, but has the capability of soaking up the big pot-holes and other road hazards. PRELOAD ADJUSTMENT— On Works shocks, threaded preload is standard. (See Fig. 2.) This allows the adjustment of the ride height of the motorcycle. The preload is changed by turning a threaded nut down towards the spring (higher ride height) or up away from the spring (lower ride height). The nut is a right-hand thread. It is used primarily to set the ride height for solo riding, but can also be used when
