ADJUSTING THE VALVE CLEARANCE
The following procedure applies to all of the
valves.
NOTE:
l
Valve clearance adjustment should be made
on a cold engine, at room temperature.
l
When the valve clearance is to be measured or
adjusted, the piston must be at top dead center
(TDC) on the compression stroke.
1. Remove:
l
Front panels
l
Seat
Refer to “GENERAL CHASSIS” on page 4-1.
l
Fuel tank
Refer to “FUEL TANK ” on page 7-1.
2. Disconnect:
l
Spark plug cap
l
Air induction system vacuum hose
l
Air induction system hose (3-way joint to air
cut-off valve)
Refer to “AIR INDUCTION SYSTEM” on
page 7-9.
3. Remove:
l
Air cut-off valve
l
Reed valve
l
Reed valve plate
Refer to “AIR INDUCTION SYSTEM” on
page 7-9.
l
Cylinder head cover
l
Cylinder head cover gasket
Refer to “CYLINDER HEAD” on page 5-6.
4. Remove:
l
Timing mark accessing screw “1”
l
Crankshaft end accessing screw “2”
5. Measure:
l
Valve clearance
Out of specification
→
Adjust.
a. Turn the crankshaft counterclockwise.

b. Align the TDC mark “a” on the magnero rotor
with the stationary pointer “b” on the magneto
cover.
c. Check that the cam lobes are positioned as
shown in the illustration.
d. Measure the valve clearance with a thickness
gauge “1”.
Out of specification
→
Adjust.
6. Adjust:
l
Valve clearance
a. Loosen the locknut “1”.
b. Insert a thickness gauge “2” between the end
of the adjusting screw and the valve tip.
