I have an original thermostat ( 55340041A ), i removed from my 2014 Monster 1200. As you can see in this video : https://youtube.com/shorts/NKU7IkCIz8w the water can freely flow through it despite it should be in closed state since I took the video at room temperature. Is this thermostat faulty or expected to let water flow through, please? Thanks for answers in advance.
