Most people find the over-temperature light only ever comes on when riding in heavy rain: not 'cos the engine's too hot, but the sensor terminal isn't well insulated so gives misleading results when wet.
Additionally, the sensor is mounted in the wrong place: it's not measuring engine temperature but that of the coolant. The most common reason for a Fazer to overheat is loss of coolant (usually due to a leaking radiator). The thermostat housing (where the sensor is) is at the top of the coolant circuit so stays cool as the engine cooks.
So the light on the console is best regarded as a guide to the weather, it's feck all use for anything else.
