What is the temp

What is the temp this bike is supposed to run at? Ive yet to see mine go over 70 Celsius. That's after a 100 km ride. It wasn't hot out but I understand it has a thermostat.Most autos run in the high 90s

Mine runs at around 70 C too.

It's good to not run too hot, but the main problem with not getting the motor and fluids hot enough is that whatever moisture has accumulated in the oil never gets in the temp range to essentially 'boil off' and evaporate that moisture. Mine generally runs in the 82-87 C, although I have seen it as high as 93 C sitting in traffic. I've yet to hit the point where the fan kicks in, though-reportedly around 103 C.

I have never been worried about the engine not running hot enough, I've only been concerned with overheating. What's the harm in not having the moisture in the oil "boil off?"

coolant temperature of 70 C does not necessarily mean the oil temperature is the same.

Combustion products such as acids build up,reducing the life of the oil.

It just seems strange that the temperature seems to float around a lot.Like the thermostat is hanging open. Normally it stays closed till the engine is up to operating temperature the keeps it there. This bike doesnt seem to do that. Ive seen in fuel injected cars that if its not hot enough the fuel efficiency goes out the window as if its running with the choke on.The computer runs rich dumping more fuel. Time will tell I guess

The ability to keep the temp to a fixed level is dependent on the cooling system's ability to shed heat.With smaller radiators on bikes you will see more variation.At highway speeds the 09 doesn't seem to vary far from 70 C.

I was under the impression that if the temp drops below normal optimum that the thermostat would close and stop the system from shedding heat. At least thats the way I've seen it work in other liquid cooled systems
