Valve Clearance
• The valve clearance must be inspected and adjusted as
needed when the engine is cold (equal to the atmospheric
air temperature).
1. Remove the cylinder head cover.
2. Align the T mark (1) on the flywheel with the fan cover mark (2)
at the top dead center in the compression stroke.
3. Measure the valve clearance using a thickness gauge.
4. If the clearance is not within the factory specifications, adjust
with the adjusting screw.
5. After tightening the lock nut and turning the flywheel twice or
three times counterclockwise, recheck the valve clearance.
