In normal operation, assuming a system in correct working order and filled with coolant, the engine will remain at the correct operating temperature almost entirely through natural convection, as air moves past the radiator. The air moving past the radiator carries away heat, removing it from the engine. In some circumstances, the cooling system either doesn't receive enough air, or doesn't receive cool enough air, and it will engage the electric fan. This typically happens when the temperature is over about 80° F (27° C), or when the bike is stopped or moving very slowly. | In normal operation, assuming a system in correct working order and filled with coolant, the engine will remain at the correct operating temperature almost entirely through natural convection, as air moves past the radiator.

The "correct operating temperature" is any temperature between the second low mark and the bottom of the red zone, which are connected together by an arc line. If the gauge shows colder than the second low mark after the engine has been warmed up, or into the red at any time, that indicates a problem with the cooling system. | The "correct operating temperature" is any temperature between the second low mark and the bottom of the red zone, which are connected together by an arc line.
