Adjusting the valves (350)
Contact point
The index marks (A) on the rocker arm shafts (B)
must be pointing away from the center ofthe cylin—
der head (350)
NOTE: Each rocker arm shaft has an
indicator slot. This slot must face the
front of the engine on the exhaust
valves and to the rear ofthe engine on
the intake valves.
8. After completing the adjustment of
the left cylinder turn the rotor coun—
terclockwise 180° and align the "T" mark
on the rotor with the timing index mark
on the stator. The right piston should be
at TDC of the compression stroke and
clearance should exist at both valves; if
not turn the rotor 360°. Repeat the adjust—
ing procedure for the right cylinder. Be
sure to recheck the adjustment after tight—
ening the rocker arm shaft locknut. Also
check that the indicator slot in the rocker
arm shaft is facing away from the center
of the engine.

1. Open the seat and raise the rear of
the fuel tank slightly.
2. Remove the spark plugs, alternator
cover, and valve covers.
3. Turn the engine over slowly in the
normal direction of rotation (coun—
terclockwise) while observing theleft in—
take valve. When the valve goes down
and then starts to rise, continue turning
the engine over until the "LT" mark on
the rotor lines up with the timing index
mark on the stator.
Tidy,
Left cylinder at top dead center when the rotor (1)
and stator index mark (2) are aligned (360)
4. The left piston should now be at top
dead center (TDC) on the compression
stroke with both valves closed. Each
valve should have a slight amount of free—
play. If they do not, the piston is at TDC
on the exhaust stroke. Turn the rotor 360°
and check again.
5. The correct valve clearance is 0.05
mm (0.002 in.) for the intake valves and
0.08 mm (0.003 in.) for the exhaust
valves.
6. Slip the correct feeler gauge be—
tween the valve stem and the rocker arm
adjuster. The feeler gauge should be a
