COOLING SYSTEM 10
5. Slowl
y
add coolant mixture to the system,
through the filler opening, until the system is full.
If the system has filled correctly and fully there
should be coolant visible through the bleed screw
opening as well as in the filler opening.
6. If there is no coolant visible through the bleed
screw opening, but the filler side appears to be
full, attach a length of clear tubing to the bleed
screw spigot and syphon coolant from the
cylinder head etc. into the bleed screw side of the
thermostat housing.
NOTE:
• A hand operated vacuum pump or similar
should be used to syphon the coolant through
the system. Ensure that the coolant that flows
into the bleed screw side of thermostat housing
comes from within the cylinder head etc. and is
not merely drawn through the thermostat from
the filler opening side.
7.
If necessary, top up the system through the filler
and refit the pressure cap.
8. Refit the bleed screw and tighten to 7 Nm.
9.
Refit the coolant pressure cap.
10. Reconnect the battery positive (red) lead first.
11. Start the motorcycle and allow the engine to idle
for a short period of time to allow any air to be
expelled from the system. In particular, check for
air—locks in the area of the radiator top hose.

RADIATOR HOSES
Regularly check all radiator hoses and hose clips for
cracks, leaks or deterioration in accordance with the
scheduled maintenance chart.
RADIATOR AND COOLING FAN
Check the radiator fins for obstruction by insects, mud,
leaves and general debris. Clean off any obstructions by
hand or with a stream of low pressure water.
WARNING: The cooling fan operates
automatically, even with the ignition
switched off. To prevent injury, keep hands and
clothing away from the fan blades at all times.
CAUTION: Using high -pressure water, as
• from a car-wash facility, can damage the
radiator fins and impair the radiator's efficiency.
Do not obstruct or deflect airflow through the
radiator by installing unauthorized accessories in
front of the radiator or behind the cooling fan.
Interference with the radiator airflow can lead to
overheating and consequent engine damage.
