Cooling system

Coolant is circulated by a water pump located in the engine. When the
engine is cold the coolant circulates only through the cylinder and the cylin-
der head. After the engine has reached its operating temperature (about
70°C, 158°F), the thermostat
pumped through both aluminum radiators.
Air blowing in through the radiators cools the coolant. The slower the speed
of the motorcycle, the less the coolant is cooled down. Dirty
radiators also reduce the cooling efficiency.
Pressure induced by heating of the coolant in the system is controlled by a

valve in the radiator cap
(248° F) is admissible, without fear of problems.

A mixture of 40% anti freeze liquid and 60% water is used as coolant.
However, the anti-freeze protection must be at least -25° C (-13° F). This
mixture offers anti-freeze protection but also good corrosion protection and
should therefore not be replaced by pure water.

The coolant should be 10 mm (0,4 in) above the radiator fins when the
engine is cold (see illustr.). In the event of the coolant being drained, always
fill and bleed the system.
