Where is the crank breather hose on a yz 426? Is this the hose coming out of the top of the head. If not what is this hose coming out of the top of the head that is routed to the botom of the motor. I need my bike to pass tech at ESRMA and just need to get this crank breather routed to the air box then I should be good.

yes it should be coming out of the valve cover and running down the left frame rail
