The motorcycle is fitted with a thermostatically controlled electric fan situated behind the radiator. The fan cowl is fitted with six flap valves to add control to the air flow through the radiator. When the motorcycle is operated at speed and the fan is off, the flap valves open to allow more air flow through the radiator. When the fan operates with the motorcycle stationary or at slow speed, the valves close to ensure cool air is drawn through the radiator from the front of the motorcycle.
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. Ensure the flap valves are not blocked or obstructed and are free to operate.
Caution! Using high-pressure water, as from a pressure washer, can damage the radiator fins and impair the radiator's efficiency.
Caution! 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.
