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.

adjuster screw with a valve adjusting wrench.
And then tighten the lock nut.
Torque : 1.1kgf-m(11N.m)
Tools : Wrench 8

Adjusting wrench
Measure the valve clearance again.
After connecting the cylinder head cover,
tighten the bolt.
Torque : 1.0kgf-m(10N.m)
Install the timing hole cap and crank case hole
cap.
Timing Hole Cap : 0.6kgf-m(6N.m)
Crank Case Hole Cap : 0.8kgf-m(8N.m)
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
f/
(550rpm)
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
head
