I have a Cometic gasket kit for my XR600 and I noticed that the valve cover gasket is a paper/fiber instead of the metal OEM gasket. Is there a downside to the paper gasket? I'm guessing that Honda used metal for dimensional stability. I'm sure that plenty of people have used the paper type gaskets. Has anyone had them cause a problem. I already got a Honda head gasket because I didn't like the cometic one. Should I get a honda valve cover gasket too?
