I have a 01 Husa fc 470 I seem to be leaking oil down the front of the motor from ythe head. I thought it was the valve cover gaskets so I replaced them. I rode for about an hour no oil leak I then started doing wheelies (cant help it makes me damb happy) then noticed the oil leaking. Any advice appreciated I did torque the head bolts they are and were in spec. Is this a normal thing I am new to Husaberg but man I have never ridden a finer bike.
