Shock absorber adjusters (fig. 37) The rear shock absorber has outer adjusters that enable you to adjust your motorcycle to the load. The adjuster (1) located on the left side, on the connection holding the shock absorber to the swingarm, controls rebound damping. The adjuster (2) on the shock absorber expansion reservoir controls compression damping. Turn the adjusters (1 and 2) clockwise to increase damping, anticlockwise to reduce it. Rebound adjuster (1) STANDARD setting: turn the adjuster all the way in (clockwise) then slacken it 1 turn and a half. Compression adjuster (2) STANDARD setting: turn the adjuster all the way in (clockwise) then slacken it 1 turn. Two ring nuts (3), located on the top section of the shock absorber are used to adjust the outer spring preload. To change spring preload, turn the upper ring nut. Then tighten or slacken the lower ring nut to increase or decrease spring preload as required. Warning Use a specific pin wrench to turn the preload adjusting nut. Be careful when turning the nut to avoid hurting your hand hitting motorcycle parts. The pin may slip out of the nut recess while carrying out such operation. Warning The shock absorber is filled with gas under pressure and may cause severe damage if taken apart by unskilled persons. E 2 3 1 fig. 37 41
