Valve Clearance

Valve Clearance, Adjust

Intake 0.11-0.18 mm (0.004331-0.007087 in.)
Exhaust 0.27-0.34mm (0.0106299-0.0133858 in.)

NOTE: A midrange clearance is the most desirable:
^ intake: 0.15 mm (0.006 inch)
^ exhaust: 0.3 mm (0.012 inch)

NOTE: Select tappets using this formula: tappet thickness = measured clearance plus the base tappet thickness minus most desirable thickness.

Select tappets and mark installation location.
