The temperature level is very long time to increase up to 50°C.
Depending on the ambiant temperature, the level coms never up to 50°C. it's not enough for a right using motor.
Do you have experience ? What's the solution ?

The oil must cross the radiators to garanty a good lubrification or is it possible to stop the oil before radiator with a termostat ?

Thanks for help

helo christian, i would stop the airflow in the radiators .close them with a strong tape like duc-tape or similar. but keep an eye onthe temp..

50°C seems too low... I usually go up to 80-100°C on summer.
Is the temperature sensor ok? Are the connector oxidated?

I have your same trouble on my dukess...
The engine is running good, however I'm in order to ceck the valve located between the pump and the oil filter... I suppose it should bypass the oil flow straight to the engine in case of troubles in the coolers.... I think I'll clean the coolers inside too, so I'll be able to tell you something about.
Have a nice ride, Ducapaso
