VALVE CLEARANCE
Inspect Initial 1 000 km (600 miles) and |
Every 6 000 km (4 000 miles)
Excessive
valve
clearance
results
in
valve
noise
and
insufficient
valve
clearance
results
in
valve
damage
and
reduced
power.
At
the
distances
indicated
above,
check
and
adjust
the
clearance
to
the
specification.
The
procedure
for
adjusting
the
valve
clearance
is
as
follows:
When
the
de-compression
cable
play
is
properly
adjusted,
the
de-compression
lever
should
have
1
—
2
mm
of
free
play
with
the
piston
at
T.D.C.
on
the
compression
stroke.
1—2mm
(0.04 — 0.08 in)
De-compression
lever play @
NOTE:
Valve clearance is to be checked when the
engine is cold.
Both the intake and exhaust valves must be
checked and adjusted when the piston is at
Top—Dead—Center (TDC) on the compression
stroke.
Remove the seat, frame covers and fuel tank.
(Refer to page 3-2)
Remove the spark plug and valve inspection
caps, intake and exhaust. (Refer to page 3-11)
CAUTION:
Before adjusting the valve clearance, check or
