PERIODIC MAINTENANCE 2-15 THROTTLE VALVE SYNCHRONIZATION Inspect initially at 1 000 km (600 miles, 2 months) (E-33 only) and every 12 000 km (7 500 miles, 24 moths). Inspect the throttle valve synchronization periodically. (5-26) EVAPORATIVE EMISSION CONTROL SYSTEM (E-33 ONLY) Inspect every 12 000 km (7 500 miles, 24 months). Replace vapor hose every 4 years. Inspect the evaporative emission control system periodically. PAIR (AIR SUPPLY) SYSTEM Inspect every 12 000 km (7 500 miles, 24 months). Inspect the PAIR (air supply) system periodically. (11-6) E L THROTTLE CABLE PLAY P Inspect initially at 1 000 km (600 miles, 2 months) and M every 6 000 km (4 000 miles, 12 months) thereafter. A Adjust the throttle cable play A as follows. S • Loosen the lock-nut 2 of the throttle pulling cable 1. • Turn the adjuster 3 in or out until the throttle cable play (at the throttle grip) A is between 2.0 – 4.0 mm (0.08 – 0.16 in). • Tighten the lock-nut 2 while holding the adjuster 3. Throttle cable play A: 2.0 – 4.0 mm (0.08 – 0.16 in)  After the adjustment is completed, check that handle- bar movement does not raise the engine idle speed and that the throttle grip returns smoothly and auto- matically.
