Control functions G G Do not deform or damage the cylinders in any way. Cylinder damage will result in poor damping performance. Do not dispose of a damaged or worn out shock absorber yourself. Take the shock absorber to a Yamaha dealer for any service. TIP The spring preload setting is determined by measuring distance A, shown in the illustration. The longer distance A is, the higher the spring preload; the shorter distance A is, the lower the spring preload. Spring preload setting*: Minimum (soft): 119.0 mm (4.69 in) Standard: 119.0 mm (4.69 in) Maximum (hard): 129.0 mm (5.08 in) * Distance A changes 1.5 mm (0.06 in) with each full turn of the adjusting nut. 3. Tighten the locknut to the specified torque. NOTICE: Always tighten the locknut against the adjusting nut, and then tighten the locknut to the specified torque. [ECS00860] Tightening torque: Locknut: 42 Nm (4.2 m·kgf, 30 ft·lbf) ESU10926 ESU10894 Adjusting the spring preload of the front shock absorbers EWS00720 WARNING The spring preload of the left and right shock absorbers must be adjusted to the same setting. Uneven settings can cause poor handling and loss of stability. The spring preload can be adjusted by turning the adjusting nuts. Adjust the spring preload as follows. 1. Loosen the locknut. 2. To increase the spring preload and thereby harden the suspension, turn the adjusting nut in direction (a). To decrease the spring preload and thereby soften the suspension, turn the adjusting nut in direction (b). 3 1 (a) 2 (b) Adjusting the damping forces of the front shock absorbers EWS00740 WARNING The damping forces of the left and right shock absorbers must be adjusted to the same settings. Uneven settings can cause poor handling and loss of stability. Compression damping force The compression damping force of each shock absorber can be adjusted by turning its compression damping force adjusting knob. To increase the compression damping force, turn the adjusting knob in direction (a). To decrease the compression damping force, turn the adjusting knob in direction (b). 1. Locknut 2. Distance A 3.
