NOTE:
EAS00045
ENGINE
ADJUSTING THE VALVE CLEARANCE
The following procedure applies to all of the
valves.

Valve clearance adjustment should be made
on a cold engine, at room temperature.

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

rider seat
Refer to “SEATS”.

fuel tank
Refer to “FUEL TANK”.

air filter case
Refer to “AIR FILTER CASE”.

bottom cowlings

side cowlings
Refer to “COWLINGS”.

throttle body assembly
Refer to “THROTTLE BODIES” in chapter 7.

6. Measure:

engine oil pressure
(at the following conditions)
Engine oil pressure
230 kPa
(2.3 kg / cm
2, 2.3 bar, 32.71 psi)
Engine speed
Approx. 5,000 r / min
Engine oil temperature
100C (212F)
Regarding the oil pressure as its own data may
fluctuate depending on the oil temperature and
viscosity, the oil pressure may fluctuate when
measuring. The following data should be used
only as a reference when measuring the engine
oil pressure.

WARNING
WARNING
EAS00162
CHECKING THE TIRES
The following procedure applies to both of the
tires.
1. Check:

tire pressure
Out of specification
Regulate.

The tire pressure should only be checked
and regulated when the tire temperature
equals the ambient air temperature.

The tire pressure and the suspension must
be adjusted according to the total weight
(including cargo, rider, passenger and ac-
cessories) and the anticipated riding
speed.

Operation of an overloaded motorcycle
could cause tire damage, an accident or an
injury.
NEVER OVERLOAD THE MOTORCYCLE.

It is dangerous to ride with a worn-out tire.
When the tire tread reaches the wear limit,
replace the tire immediately.
