NOTICE: Valve clearance must be checked when the
engine is cold (at room temperature).
With the rocker cover removed, Place the piston at TDC
of the compression stroke turning the crankshaft in its
rotational direction.
Then check the valve clearance with a feeler gauge (7),
measure the valve clearance between the rocker arm (8)
and the valve stem end.
Valve Clearance (when cold): Inlet, Exhaust 0.10 - 0.15
mm (0.004 - 0.006 in.)
