A diagnostic tachometer must be used for this procedure.
1. Start the engine and warm it up for a few minutes at approximately 1,000 to 2,000r/min. Occasionally rev the
engine to 4,000 to 5,000 r/min. The engine is warm when it
quickly responds to the throttle.
2. Remove panel.
3. Connect the tachometer to the spark plug lead, and then set
the idle to the specified idling speed by adjusting the throttle
stop screw. Turn the screw in direction to increase the
engine speed, and in direction to decrease the engine
speed.
Specified idle speed:1,200
1,400 r/min
4. Install the panel.
The correct valve clearance changes with use, resulting in improper fuel/air supply or engine noise. To prevent
this, the valve clearance must be adjusted regularly. This adjustment however, should be left to a professional
service technician.
