VALVE CLEARANCE CHECK/
ADJUSTMENT
Disconnect the breather hose (1).
Remove the head cover bolt (2), the head cover (3).
Check the head cover packing (4) for damage or
deterioration and replace if necessary.
Disconnect the spark plug cap from the spark plug.
Set the piston near top dead center of the cylinder
compression stroke (both valves fully closed) by pulling
the recoil starter slowly. When the piston is near top
dead center of the compression stroke, the triangle
mark (1) and cut-out (2) on the starter pulley will align
with the top hole (3) on the recoil starter case (4).
If the exhaust valve is opened, use the recoil starter to
turn the crankshaft one additional turn and align the
triangle mark on the starter pulley with the top hole on
the recoil starter case again.
Insert a thickness gauge (1) between the valve rocker
arm (2) and valve stem (3) to measure the valve
clearance.
VALVE CLEARANCE:
IN: 0.15 ± 0.02 mm
EX: 0.20 ± 0.02 mm
If adjustment is necessary, proceed as follows.
Hold the rocker arm pivot (4) and loosen the pivot
adjusting nut (5).
Turn the rocker arm pivot to obtain the specified
clearance.
VALVE CLEARANCE:
IN: 0.15 ± 0.02 mm
EX: 0.20 ± 0.02 mm
Hold the rocker arm pivot and retighten the pivot
adjusting nut to the specified torque.
TORQUE: 10 N·m (1.0 kgf·m, 7 lbf·ft)
Recheck the valve clearance, and if necessary, readjust
the clearance.
Attach the cylinder head cover to the cylinder head, and
tighten the head cover bolt securely.
