Check: S throttle cable free play a Out of specification ! Adjust. Throttle cable free play (at the flange of the throttle grip) 3 X 5 mm 2. Adjust: S throttle cable free play NOTE: When the motorcycle is accelerating, the accelerator cable 1 is pulled. Carburetor side a.
ADJUSTING THE THROTTLE CABLE FREE PLAY CHK ADJ Direction a Throttle cable free play is increased. Direction b Throttle cable free play is decreased. d. Tighten the locknut. WARNING After adjusting the throttle cable free play, turn the handlebars to the right and to the left to ensure that this does not cause the engine idling speed to change.
CHECKING AND CHARGING THE BATTERY CHK ADJ EAS00178 ELECTRICAL SYSTEM CHECKING AND CHARGING THE BATTERY WARNING Batteries generate explosive hydrogen gas and contain electrolyte which is made of poisonous and highly caustic sulfuric acid. Therefore, always follow these preventive measures: S Wear protective eye gear when handling or working near batteries. S Charge batteries in a well-ventilated area. S Keep batteries away from fire, sparks or open flames (e.g., welding equipment, lighted cigarettes).
CHECKING AND CHARGING THE BATTERY CHK ADJ NOTE: Since MF batteries are sealed, it is not possible to check the charge state of the battery by measuring the specific gravity of the electrolyte. Therefore, the charge of the battery has to be checked by measuring the voltage at the battery terminals. 1. Remove: S seat 2. Disconnect: S battery leads (from the battery terminals) CAUTION: First, disconnect the negative lead 1 , then the positive lead 2 . 3. Remove: S battery 4. Check: S battery charge a.
CHECKING AND CHARGING THE BATTERY CHK ADJ 5. Charge: S battery (refer to the appropriate charging method illustration) Charging Open-circuit voltage (V) Ambient temperature 20_C WARNING Do not quick charge a battery. Time (minutes) Check the open-circuit voltage. CAUTION: S Make sure that the battery vent is free of obstructions. S Never remove the MF battery sealing caps. S Do not use a high-rate battery charger.
CHK ADJ CHECKING AND CHARGING THE BATTERY Charging method using a variable voltage charger Measure the open-circuit voltage prior to charging. Connect a charged and AMP meter to the battery and start charging. YES Make sure that the current is higher than the standard charging current written on the battery. NOTE: Voltage should be measured 30 minutes after the machine is stopped. NOTE: Set the charging voltage at 16 X 17 V. (If the setting is lower, charging will be insufficient.
CHECKING AND CHARGING THE BATTERY CHK ADJ Charging method using a constant voltage charger Measure the open-circuit voltage prior to charging. NOTE: Voltage should be measured 30 minutes after the machine is stopped. Connect a charger and AMP meter to the battery and start charging. YES Make sure that the current is higher than the standard charging current written on the battery. Charge the battery until the battery’s charging voltage is 15 V.
CHECKING AND CHARGING THE BATTERY CHK ADJ 6. Check: S battery vent Obstruction ! Clean. Damage ! Replace. 7. Install: S battery 8. Connect: S battery leads (to the battery terminals) CAUTION: First, connect the positive lead 1 , then the negative lead 2 . 9. Check: S battery terminals Dirt ! Clean with a wire brush. Loose connection ! Connect properly. 10. Lubricate: S battery terminals Recommended lubricant Dielectric grease 11.
REPLACING THE HEADLIGHT BULB CHK ADJ EAS00182 REPLACING THE HEADLIGHT BULB 1. Remove: S bolts 1 S headlight unit 2. Disconnect: S headlight coupler 1 S headlight bulb cover 2 3. Remove: S headlight bulb holder 1 S headlight bulb 2 WARNING Since the headlight bulb gets extremely hot, keep flammable products and your hands away from the bulb until it has cooled down. 4. Install: S headlight bulb New Secure the new headlight bulb with the headlight bulb holder.
ADJUSTING THE HEADLIGHT BEAM CHK ADJ EAS00184 ADJUSTING THE HEADLIGHT BEAM 1. Adjust: S headlight beam (vertically) a. Turn the adjusting screw 1 in direction a or b. Direction a ! Headlight beam is raised. Direction b ! Headlight beam is lowered. 2. Adjust: S headlight beam (horizontally) a. Turn the adjusting knob 2 in direction a or b. Direction a !
