3. Using feeler gauges, measure and record the clearances for this pair of valves only.
4. Repeat the process until the valve clearances for all valves have been checked.
NOTICE
The correct valve clearances are in the range given below:
Inlet
0.09-0.14 mm
Exhaust
0.18-0.23 mm
If the valve clearances are not checked and corrected, wear could cause the valves to
remain partly open, which lowers performance, burns the valves and valve seats and
may cause serious engine damage.
5. Record the measured valve clearances on a chart similar to the example shown.
