Nope stock location, i have an aftermarket sensor/gauge and also the standard sensor which I read off the power FC. Seemed weird to me at first too, I thought the thermostat was faulty but I spoke to Trent and he reckons its normal?!?! Apprantly his laurel does the same thing.
Im changing the hoses soon so ill test in some water on the stove, seems crazy to think that the water is sitting stagnate and the oil system alone is cooling it.
