Intake valve clearance (Cold):
0.15 – 0.25 mm (0.006 – 0.010 in.)

EXAMPLE:  The 2.800 mm (0.1102 in.) shim is installed, and
the measured clearance is 0.450 mm (0.0177 in.)
Replace the 2.800 mm (0.1102 in.) shim with a new No.12 shim.

HINT:  New shims have the thickness in
millimeters imprinted on the face.
