TUNING 191 the rebound damping. • Increase the rear shock absorber spring preload. • Decrease Decrease 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 amount. Increase the front fork spring preload or use a harder spring. The rear suspension is too soft. Increase the rear shock absorber spring preload or use a harder spring. Increase the rear shock absorber high speed compression damping or use a harder spring. Rear End Bottoms After 3 or 4 Successive Jumps Decrease the rebound damping. • ○The rear shock absorber behavior on this machine may mislead some riders. ○The rear shock absorber bottoms (due to full NOTE stroke) when the spring and damping are overcome by the total weight of the machine and rider. ○A 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. ○Observe the rear end jumps and try lowering the spring preload and damping if it does not approach bottoming. j ○Check the front and rear suspension compatibility after making any adjustment. NOTE • • Rear End Feels Soft at Small Jump Increase the spring preload up to maximum. Increase the rear shock absorber low speed compression damping. Rear End Feels Soft at Large Jump - the spring preload up to maximum. • Increase the rear shock absorber high speed com• Increase pression damping.
