●
Measure the valve clearance with filler gauge.
Valve Clearance:
Intake: 0.12
±
0.02mm(0.05
±
0.001in)
Exhaust: 0.12
±
0.02mm(0.05
±
0.001in)
●
Loosen the lock nut with a valve wrench, and
adjust the adjuster screw to the standard
clearance using a valve adjusting wrench.
When the standard clearance is done, hold the
adjuster screw with a valve adjusting wrench.
And then tighten the lock nut.

●
After connecting the cylinder head cover,
tighten the bolt.

Install the timing hole cap and crank case hole
cap.

Cylinder Compression Pressure
●
Warm up the engine to normal operating
temperature.
●
Stop the engine, disconnect the spark plug
caps and spark plug. Install the compression
gauge.
●
Open the throttle all the way and crank the
engine with the starter motor until the gauge
reading stops rising.
Tool: Compression gauge
•
The maximum reading is usually reached
within 4~7 seconds.
Compression Pressure : 14.0

If compression is low, check the following:
•
Incorrect valve clearance adjustment
•
Valve for leakage
•
Exposed cylinder head from the gasket
•
Worn piston/cylinder
If compression is high, check the following:
•
Carbon deposits on the piston head, cylinder
