• Clean and fit the cylinder head and valve components. Fill the
intake and exhaust ports with petrol and check that there are no
leaks. If any leaks are found, check for burrs or other factors that
prevent the valve seat and the seating surface from sealing prop-
erly.
Handle petrol with the utmost care.
After servicing the valve seats and reinstalling the cylinder head, be
sure to check the tappet clearance (see pages 2-6 to 2-10).
VALVE SPRING
The push of the spiral spring ensures the valve seal. A weakened
spring results in reduced power output and often accounts for ab-
normal noise from the valve gear mechanisms. Check the strength
of the springs by measuring their free length and the force required
to compress them. If the free length is less than specified, or if the
force required for compression is not in the specified range, replace
both the inner and the outer spring.
