Use coolant containing corrosion inhibitors made
specifically for aluminum engines and radiators in
accordance with the instruction of the manufac-
ture's. Soft or distilled water must be used with the
antifreeze (see below for antifreeze) in the cooling
If hard water is used in the system, it
causes scale accumulation in the water passages,
and considerably reduces the efficiency of the
Replace the drain bolt gasket with a new one.

Fill the radiator up to the bottom of the radiator filler neck
[A] with coolant [B].
Lean the motorcycle slightly so that the filler neck is lo-
cated uppermost in order to exhaust the air accumulated
in the radiator.
Pour in the coolant slowly so that it can expel the air
from the engine and radiator.
Loosen the air bleeder screw [A] on the top of the left
radiator until the coolant begins to flow out from the air
bleeder screw hole.
Replace the O-ring of the air bleeder screw with a new
Torque - Air Bleeder Screw: 1.6 N·m (0.16 kgf·m, 14 in·lb)
Install the radiator cap.
The radiator cap must be installed in two steps. First
turn the cap clockwise to the first stop. Then push down
on it and turn it the rest of the way.
Check the cooling system for leaks.
Permanent type antifreeze (soft water
and ethylene glycol plus corrosion
and rust inhibitor chemicals for
aluminum engines and radiators)
