AIR BLEEDING THE COOLING CIRCUIT
1) Add engine coolant up to the radiator inlet.
2) Support the motorcycle upright.
3) Slowly swing the motorcycle, right and left, to bleed the air
trapped in the cooling circuit.
4) Add engine coolant up to the radiator inlet.
5) Start up the engine and bleed air from the radiator inlet com-
pletely.
6) Add engine coolant up to the radiator inlet.
7) Repeat the above procedure 4) – 5) until no air bleeds from

.
9) Loosen the water pump air bleeder bolt

and check the
engine coolant flows out.
10) Tighten the water pump air bleeder bolt to the specified
torque.
Water pump air bleeder bolt: 6 N·m (0.6 kgf-m, 4.5 lbf-ft)
11) Close the radiator cap securely.
12) After warming up and cooling down the engine several
times, add the engine coolant up to the full level of the res-
ervoir tank.
Engine coolant capacity:
Engine side
: 1 100 ml (1.2/1.0 US/Imp qt)
Reservoir tank side : 250 ml (0.3/0.2 US/lmp qt)
RADIATOR HOSES
• Remove the fuel tank covers. (
8-5)
• Check the cramp screws and radiator hoses for crack, dam-
age or engine coolant leakage.
• If any defects are found, tighten the clamp or replace the radi-
ator hose with a new one.
Water hose clamp screw: 1.5 N·m (0.15 kgf-m, 1.0 lbf-ft)
Make sure that the radiator is filled with engine cool-
ant up to the reservoir full level.
