2-8 PERIODIC MAINTENANCE
SPARK PLUG GAP
Measure the spark plug gap using the thickness gauge. If the
spark plug gap is out of specification, adjust the gap.
% Standard
Spark plug gap: 0.6 0.7 mm (0.024 0.028 in)
$ 09900-20803: Thickness gauge or
09900-20804: Thickness gauge
ELECTRODE
Check the condition of the electrode.
If the electrode is extremely worn or burnt, replace the spark
plug with a new one.
Also, replace the spark plug if it has a broken insulator, dam-
aged threads, etc.

SPARK PLUG INSTALLATION
"
# Spark plug: 18 N•m (1.8 kgf-m, 13.0 lb-ft)
FUEL LINE
Inspect the fuel hose for damage and fuel leakage. If any
damages are found, replace the fuel hose with a new one.
0.6 0.7 mm
(0.024 0.028 in)
Check the thread size and reach of the spark plug. If
the reach is too short, carbon will be deposited on the
screw portion of the spark plug hole and engine dam-
age may result.
To avoid damaging the cylinder head threads; first,
finger tighten the spark plug, and then tighten it to the
specified torque using the spark plug wrench.
Inspect every 3 months.
Replace every 4 years.
