Subject: R:Radiators, temperature, ...


Veli says : ...
The temperature
of the cooling liquid is normally controlled by the thermostat, which
closes the water circuitry if the temperature is to low. Needing to
cover the radiators would mean that the engine doesn't heat enough even
if the thermostat is closed (I would have something to say to some Honda
engineers then) or that the thermostat isn't working properly (could
happen if it's stuck open) or that you're a real biker who is not afraid
to ride by -15° (even though..).
That is not correct. The main reason of the slow rising of the temperature is due to a bad behavior of the old 650 model. In very hot temperature, the XRV650 overheats; for that reason the new XRV750 tends to warm up much slower. The counterpart is that, in winter, the REAL TEMPERATURE of the engine is lower than in XRV650. Honda dealers says to close both the radiators at least 50-60% but you can easily see how the temperature behaves. Especially if the bike is brand new consider closing the 80% of both the radiators if the temperature is below 0 degree and if you drive outside city (it means very few stops).
I usually close the radiators with adhesive bands and if the temperaturegets warmer, or if I drive in town, I remove some bands.
