TUNING 173 Front and Rear Ends Bottom Off After a Highspeed 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. 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. NOTE • • ○ The rear shock absorber behavior chine may mislead some riders. ○ The rear shock absorber bottoms on this ma- • • (due to full 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. NOTE ○ Check the front and rear suspension compatibility after making any adjustment. • • Rear End Feels Soft at Small Jump Increase the spring preload up to maximum. Increase the rear shock absorber low speed compression damping. the spring preload up to maximum. • Increase Increase the rear shock absorber high speed • compression damping. Rear End Bottoms After 3 or 4 Successive Jumps Decrease the rebound damping. Rear End Feels Soft at Large Jump - •
