Valve Clearance

Valve Clearance

NOTE: The shims are marked for thickness; example: 2.22 mm = 222 on shim.

NOTE: The corrected shims allow the following valve clearances.
^ Intake valve clearance: 0.18 - 0.22 mm (0.00709 - 0.00866 inch)
^ Exhaust valve clearance: 0.33 - 0.38 mm (0.0128 - 0.0148 inch)

NOTE: A midrange clearance is the most desirable:
^ Intake: 0.20 mm (0.00787 inch)
^ Exhaust: 0.35 mm (0.014 inch)

NOTE: Select shims using this formula: required shim thickness = measured clearance plus the base shim thickness minus most desirable clearance.
