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.
Torque : 1.1kgf-m(11N.m)
Tools : Wrench 89mm

 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.

Crank Case Hole Cap : 0.8kgf-m(8N.m)
Cylinder Compression Pressure
 Warm up the engine to normal operating

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
