Periodic Maintenance Procedures


Crankshaft Inspection

Connecting Rod Big End Side Clearance
Remove the cylinder head (see Cylinder Head Removal
in the Engine Top End chapter).
Remove the cylinder (see Cylinder Removal in the Engine
Top End chapter).
Remove the piston (see Piston Removal in the Engine
Top End chapter).
Measure the connecting rod big end side clearance at
right side of big end using a thickness gauge [A].
Connecting Rod Big End Side Clearance
0.25 ∼ 0.35 mm (0.0098 ∼ 0.014 in.)
Service Limit: 0.6 mm (0.02 in.)
If the clearance exceeds the service limit, replace the
crankshaft assembly.
Make sure that the crankshaft rotates smoothly after as-
sembling the engine.


Air Pressure Inspection/Adjustment

Using tire air pressure gauge [A], measure the tire pres-
sure when the tires are cold.
Adjust the tire air pressure to suit track conditions and
rider preference, but do not stray too far from the recom-
mended pressure.
Track Condition
When the track is wet, muddy, sandy
or slippery, reduce the tire pressure
to increase the tire tread surface on
the ground.
When the track is pebbly or hard,
increase the tire pressure to prevent
damage or punctures, through the
tires will skid more easily.
Tire Pressure
80 kPa (0.8 kgf/cm²,
11 psi)
100 kPa (1.0 kgf/cm²,
14 psi)
