1. If there is carbon adhering to the spark plug, perform no-load racing at
4,000 rpm for 2 min, 2 times
.
VISUAL INSPECTION
1. Inspect the following items:
If any of the following malfunction are indicated, replace the spark plug.
Insulator breakage
Worn electrode
Damaged gasket
Badly burned insulator (sparking side)
there is any malfunction such as rough idling or start difficulty due to
carbon adhesion causing plug fouling, burn off the carbon by
performing no-load racing of the engine.
When performing the no-load racing, apply the side brake and foot
brake, move the shift lever to neutral (MT), or the selector lever to P
position (AT) to prevent an accident and serious injury.
To avoid possible damage to the spark plug tip, do not use a wire
brush for cleaning.
NOTE:
To avoid possible damage to the tip, use gasoline to clean the spark plugs
after removing dirt.
If the accelerator pedal is depressed continuously for a specified time, the
engine speed may decrease to the idle speed. This is due to the fuel cut
control operation, which prevents overheating, and it does not indicate a
malfunction.
Do not perform no-load racing at high engine speed continuously for 10s
or more.
