106 MAINTENANCE AND ADJUSTMENT setting, turning it clockwise 40 or more clicks (depending on the model) is the hardest setting. Fork Oil Amount Adjustment The fork oil amount affects only the final 100 mm (4 in.) of fork travel. A higher oil amount will make the fork rebound more quickly. A lower oil amount will make the fork rebound more slowly. Fork Springs Optional springs, softer and stiffer than standard, are available. Fork Height Steering is greatly affected by the fork height (how much the outer fork tubes protrude above the steering stem head). The less the fork tube protrudes, the lighter the front end becomes and the greater the tendency for understeering and washout due to weight biasing. Increasing the amount of fork tube protrusion has opposite effects. Be sure that the front tire does not touch the fender when the fork is fully compressed. Make this adjustment in 10 mm (0.39 in.) steps. air pressure relief screw located in left front fork base valve assembly and right front fork top plug. Make sure the front forks are fully extended with the front wheel off the ground when releasing the pressure. Raise the front wheel off the ground using a jack (special tool: 57001-1238) and attachment (special tool: 57001-1608). Remove the screw on each front fork top plug to let the air pressure equalize. Then, tighten the screws. j • • • • • Tightening Torque Air Pressure Relief Screws: 1.3 N·m (0.13 kgf·m, 12 in·lb) NOTICE The right and left fork tubes must be adjusted evenly. The standard air pressure in the front fork legs is atmospheric (0 kPa, 0 kgf/cm², 0 psi). Air pressure in the fork legs increase with normal use, so the fork action stiffens during operation. Release air pressure from the fork legs prior to each race through the Air Pressure Adjustment A. Screw B. Left Front Fork Base Valve Assembly C. Front Fork (Left Side)
