VISUALLY INSPECT SPARK PLUGS
Check the spark plug for thread or insulator damage.
If abnormal, replace the plug.
Recommended spark plugs:
ND
PQ16R
NGK BCPR5EPll
7M-GTE ND
PQ20R-P6
NGK BCPRGEP-N8
INSPECT ELECTRODE GAP
Maximum electrode gap:
7M-GE
1.3 mm (0.051 in.)
7M-GTE 1.0 mm (0.039 in.)
If the gap is greater than maximum, replace the plug.
Correct electrode gap of new plug:
7M-GE
1.1 mm (0.043 in.)
7M-GTE 0.8 mm (0.031 in.)
If adjusting the gap of a new plug, bend only the base of

the ground electrode, do not touch the tip.
If the electrode has traces of wet carbon, allow it to dry
and then clean with a spark plug cleaner.
Air pressure: Below 6 kg/cm2 (85 psi, 588 kPa)
Duration : 20 seconds or less
NOTE:
If there are traces of oil, remove it with gasoline
before using the spark plug cleaner.
INSTALL SPARK PLUGS
(a) Using SST, install and torque the spark plug.

Torque : 180 kg-cm (13 ft-lb, 18 N*m)
(b) Install the high-tension cords.
