C: INSPECTION
1. CYLINDER HEAD
1) Make sure that no crack or other damage exists. In
addition to visual inspection, inspect important areas by
means of red lead check.
Also make sure that gasket installing surface shows no
trace of gas and water leaks.
2) Place cylinder head on ST.
ST 498267200 CYLINDER HEAD TABLE
G2M0148
3) Measure the warping of the cylinder head surface that
mates with crankcase by using a straight edge and thick-
ness gauge.
If the warping exceeds 0.05 mm (0.0020 in), regrind the
surface with a surface grinder.
Warping limit:
0.05 mm (0.0020 in)
Grinding limit:
0.1 mm (0.004 in)
Standard height of cylinder head:
98.3 mm (3.870 in)
CAUTION:
Uneven torque for the cylinder head bolts can cause
warping. When reassembling, pay special attention to
the torque so as to tighten evenly.

presented below.
2) To measure the squareness of the valve spring, stand
the spring on a surface plate and measure its deflection at
the top using a try square.
