(X) Measurement of compressive force
CAUTION:
Inadequate compressive force will reduce the en
-
gine performance.
Before measuring the compressive force, the valve
clearance should be adjusted first (refer to “Adjust
-
ment of valve clearance” section).
1. Put vehicle on level ground
2. Take the spark plug off
3. The following are steps for measuring compres
-
sive force:
a. Install pressure gauge (1) and change connec
-
tor.
b. Turn the throttle lever to max position.
Start engine with power (battery has been charged
fully) until there is no increase on the pressure
gauge.
WARNING:
When starting the engine, the spark plug must be
connected to ground to avoid sparks.
c. Reading the pressure gauge
Compressive foce on sea level:
Standard value: 900Kpa (9.0kg/cm²)
Min. value: 800Kpa (8.0kg/cm²)
Max value: 1000Kpa (10.0kg/cm²)
