Hi, Just bought a new 650cc Sport engine and and it has some sort of air bypass valve on the top of the fan housing between the air filter and carburetor.
When the Lever is moved to the open position, a small section opens and bleeds out cooling air. It can be locked in the open or closed position. My old motor Doesn't have this. Does anyone know what this is used for? Compartment cooling maybe? Photo's show it open and closed.
Thanks in advance
