176 TUNING the rebound damping. • Increase Decrease rear shock absorber spring preload. • Decrease the the compression damping. • Front and Rear Ends Bottom Off After a High-speed Jump (harsh bottoming occurs once or twice per lap) The front suspension is too soft. Increase the fork oil capacity. Increase the front fork spring preload or use a harder spring. The rear suspension is too soft. Rear End Bottoms After 3 or 4 Successive Jumps Decrease the rebound damping. • NOTE j • • żThe rear shock absorber behavior on this machine may mislead some riders. żThe rear shock absorber bottoms (due to full stroke) when the spring and damping are overcome by the total weight of the machine and rider. żA bottoming sensation (even though the machine is actually not bottoming) may be caused by machine weight and the inability of the rider to overcome an overly stiff spring or excessive damping. żObserve the rear end jumps and try lowering the spring preload and damping if it does not approach bottoming. the rear shock absorber spring preload • Increase or use a harder spring. the rear shock absorber high speed com• Increase pression damping or use a harder spring.
