•Verify that the piston is located at the top dead
center.
● Measure the valve clearance with feeler gauge.
VALVE CLEARANCE : INTAKE 0.1±0.02MM
● Loosen the lock nut with a valve wrench,and set
valve clearance to the prescribed level by turning the
adjusting screw with a valve adjusting wrench,and
tighten the lock nut.
● After setting clearance to the prescribed level, hold
the adjuster screw with a valve adjusting wrench,and
tighten the lock nut.

PRESSURE
● Start and warm up the engine.
● Stop the engine, and remove the spark plug cap and
spark plug.
● Install the compression gauge.
● Open the throttle completely, and crank the engine
with the starter motor until the gauge reading rising.
TOOL : COMPRESSION GAUGE
NOTE
•The maximum reading is usually reached within
4~7 seconds.
COMPRESSION PRESSURE : 10 kgf/cm
● If the pressure is low, check the following:
-Inadequate valve clearance adjustment
-Valve leakage
-Leakage from the cylinder head gasket
-Piston/ cylinder worn.
● If pressure is high, check the following:
-Carbon deposits on the piston head, and cylinder
head
