    Hello everyone. I am in the south of France, despite the cold I take advantage of the sunny days to ride the Scrambler. But I noticed that the engine temperature does not manage to rise to be able to accelerate a bit and fully enjoy it.
    Example:
    Outside temperature 11 ° C / 51.8 ° F
    A 20km / 12.42 mile ride, the engine temperature rose to 50 ° C / 122 ° F.
    When I drove at 80kmh / 49.7mph, the temperature dropped a few degrees due to the cold of winter. So I dare not exceed 3500rpm, so as not to damage the engine.
    Do you have the same?

    Hi, good question , I’ve noticed the same on an evening ride (very worrying if you know an engine can suffer a cold seasure), the temperature sensor is low in the radiator , so it’s not actually measuring the temperature the engine is running at ! maybe John Drogan can give us the official CCM advice on this question.
    regards martin

    Hi Martin, yes good remark on the position of the sensor!
    It indicates the temperature of the radiator and not of the engine!
    Despite the calorstat which opens at 87 ° C / 188.6 ° F
    , liquid still circulates a little in the radiator when it is closed!
    This slows down the time it takes for the engine to heat up!
