Valve Clearance

NOTE: The number on the valve tappet only reflects the digits that follow the decimal. For example, a tappet with the number 0.650 has the thickness of 3.650 mm.

NOTE: A midrange clearance is the most desirable:
^ Intake: 0.22-0.28 mm (0.008-0.011 inch)
^ Exhaust: 0.27-0.33 mm (0.010-0.013 inch)
