Make sure that the piston is on the
top of the compression stroke.
3. Insert a clearance gauge
between the adjusting screw and
valve stem to ensure a proper
clearance of the exhaust valve.
4. Standard valve clearance
Intake valve clearance:
0.04-0.05mm
Exhaust valve clearance:
0.05-0.06mm
5. To obtain a proper valve
clearance, loose the adjusting nut
and then turn the mating screw.
Turn the adjusting nut on the
completion of adjustment and
measure the clearance until it
meets the criteria.
Note:
As the valve clearance imposes a
marked impact on the engine
performance,
inspection
and
adjustment
shall
be
severely
observed at a regular time interval
specified
in
the
Scheduled
Maintenance Scheme.
The valve clearance increases
with the passage of time and thus
affects engine performances by
producing
loud
noise
and
abnormal
suction/exhaust
processes.
Therefore
periodic
adjustment, preferably done by
professionals with special tools, of
valve clearance is essential. To
obtain an optimal valve clearance,
the adjustment is recommended to
be finished by the motorcycle
distributors or the maintenance
center.
Valve clearance adjustment is
essential for new motorcycles on
the completion of their first 1000
km.
Adjustment of clutch
Clutch adjustment is made
through adjusting the tension of
wire rope for clutch grip. Before
feeling the gear disengagement by
pressing the clutch grip, the wire
clearance measured at clutch grip
shall be 4 mm. If the clutch wire
clearance is found incorrect, carry
out adjustment as follows.
