MAINTENANCE AND TUNE-UP PRO- CEDURES This section describes the servicing procedures for each item of the Periodic Maintenance requirements. AIR CLEANER I Inspect every 6 000 km (4 000 miles, 6 months) and replace every 18 000 km (11 000 miles, 18 months) . • * Remove the seat. (LF6-7) • * Lift and support the feul tank . (C-74-65) • * Remove the air cleaner box cap O. • * Remove the air cleaner element O. • * Carefully use air hose to blow the dust from the cleaner ele- ment. CAUTION Always use air pressure on the throttle body side of the air cleaner element . If air pressure is used on the other side, dirt will be forced into the pores of the air cleaner element thus restricting air flow through the air cleaner element . PERIODIC MAINTENANCE 2-5 2-6PERIODIC MAINTENANCE • * Reinstall the cleaned or new air cleaner element in the reverse order of removal . CAUTION If driving under dusty condition, clean the air cleaner element more frequently. The surest way to accelerate engine wear is to use the engine without the element or to use a ruptured element. Make sure that the air cleaner is in good condition at all times. Life of the engine depends largely on this component! NOTE: When cleaning the air cleaner element, drain water from the air cleaner by removing the drain plug . SPARK PLUG Inspect every 6 000 km (4 000 miles, 6 months) and replace every 12 000 km (7 500 miles, 12 months) .

HEAT RANGE • * Check to see the heat range of the plug . CARBON DEPOSIT •Check to see if there are carbon deposits on the plugs . If carbon is deposited, remove it with a spark plug cleaner machine or carefully using a tool with a pointed end . SPARK PLUG GAP • * Measure the plug gap with a thickness gauge . If out of specification, adjust it to the following gap . 09900-20803 : Thickness gauge Spark plug gap OA Standard: 0.6 – 0 .7 mm (0.024 -0.028 in) ELECTRODES CONDITION •Check to see the worn or burnt condition of the electrodes . If it is extremely worn or burnt, replace the plug . And also replace the plug if it has a broken insulator, damaged thread . CAUTION Confirm the thread size and reach when replacing the plug. If the reach is too short, carbon will be deposited on the screw portion of the plug hole and engine damage may result
