Measuring piston protrusion
1. Install the dial gauge
1
and dial gauge
stand
2
to the cylinder contact surface and
set the scale of the dial gauge to zero.
Dial gauge and stand:
YU-3097/90890-01252
Offset dial stand:
YU-1037

NOTE:
• Finish the break-in before changing the gas-
ket.
• A change of 0.1 mm (0.004 in) for the gasket
causes a change of approximately 0.23 cm
3
(0.008 lmp oz, 0.008 US oz) of the combus-
tion chamber volume.
• After break-in, change to an appropriate gas-
ket to allow the piston protrusion to be -0.15
mm (-0.006 in) to 0.05 mm (0.002 in).

CAUTION:
• Piston protruding amount must be a maxi-
mum 0.15 mm (0.006 in). Above this value,
the piston and cylinder head may contact
each other.
• Too much random piston protrusion at
low temperature may develop an abnor-
mal combustion (detonation), which may
adversely affect the intended performance
of the engine.
