ADJUSTING ENGINE VALVE CLEARANCE
1.
Remove the rocker arm cover. Torque the cylinder head
bolts to 85 N•m (63 ft-lb) before adjusting the valves.
The valve clearance should be checked after the first
500 hours of engine operation.
It is very important that the valves be adjusted to the
correct specifications for satisfactory engine operation.
Insufficient valve clearance will result in compression
loss and misfiring resulting in burned valves and seats.
Excessive valve clearance will result in noisy valve
operation and abnormal wear of the valves and rocker
arms. The intake and exhaust valves are adjusted with
the valves closed.
2.
The valves are adjusted to 0.4 mm (0.016 in.). When
the right gap is obtained, MAKE SURE to tighten the
lock nut while holding the adjusting screw in position.
Turn the engine using a wrench on the front crankshaft
bolt.
