Valve

Inspect valve stem and valve seating face to make sure they are in good condi-
tion. There should be no signs of pitting, cracking, distortion or wear. Check for
the following:
- Valve stem runout: place valve on a V block and measure runout with a dial
gauge. (Service limit: 0.05 mm).
- Valve head out-of-round: place valve on a V block and check with a dial gauge
at right angles to the head while turning the valve. (Service limit: 0.03 mm).

Valve spring

Check free length "L". Replace springs if they exceed the service limit.
Intake: Spring 1 - L1 = 25 mm
Spring 2 - L2 = 25 mm
Exhaust: Spring 1 - L2 = 25 mm
Spring 2 - L2 = 25 mm
Replace all valve springs whenever any one spring exceeds
the service limit.
