3) Measure the flatness of the cylinder head sur-
face that mates with crankcase using a straight
edge (A) and thickness gauge (B).

Uneven torque for the cylinder head nuts can
cause warping. When reinstalling, pay special at-
tention to the torque so as to tighten evenly.
2. VALVE SEAT
Inspect the intake and exhaust valve seats, and
correct the contact surfaces with a valve seat cutter
if they are defective or when valve guides are re-
placed.
Valve seat width W:
Intake
Standard
1.0 mm (0.039 in)
Exhaust
Standard
1.5 mm (0.059 in)

1) Check the clearance between valve guide and
stem. The clearance can be checked by measuring
respectively the outer diameter of valve stem and
inner diameter of valve guide with a micrometer.
Clearance between the valve guide and valve
stem:
Standard

exceeds the standard, replace the valve guide or
valve itself whichever shows greater amount of
wear or damaged and etc. See the following proce-
dure for valve guide replacement.
