5. VISUALLY INSPECT SPARK PLUGS
Check the spark plug for thread damage and insulator dam-
age.
If abnormal, replace the spark plug.
Recommended spark plug:
ND PQ20R
NGK BCPR6EP–11
6. INSPECT ELECTRODE GAP
Maximum electrode gap:
1.3 mm (0.051 in.)
If the gap is greater than maximum, replace the spark plug.
Correct electrode gap of new spark plug:
1.1 mm (0.043 in.)
NOTICE: If adjusting the gap of a new spark plug, bend
only the base of the ground electrode. Do not touch the
tip. Never attempt to adjust the gap on the used plug.
7. CLEAN SPARK PLUGS
If the electrode has traces of wet carbon, allow it to dry and
then clean with a spark plug cleaner.
Air pressure:
Below 588 kPa (6 kgf/cm
2
, 85 psi)
Duration:
20 seconds or less
HINT: If there are traces of oil, remove it with gasoline before
using the spark plug cleaner.
8. INSTALL SPARK PLUGS
Using a 16 mm plug wrench, install the spark plug.
Torque: 18 N⋅m (180 kgf⋅cm, 13 ft⋅lbf)
9. RECONNECT HIGH–TENSION CORDS TO SPARK
PLUGS
10. REINSTALL V–BANK COVER
Using a 5 mm hexagon wrench, install the V–bank cover with
the two nuts.
