Hello,

 I ordered a cylinder head cover gasket and bolt grommets from megazip and replaced them the other week . when i removed the breather tube that goes from the port on the top of the cover to the carb and airbox  i noticed that there was what appears to be a piece of fibre like mesh that was in the hose just after the port on the cylinder head cover . is the normal or was it  likely put in my previous owner ? im just wondering if it would cause too much of a restriction. i changed the gasket and grommets as it was leaking badly because the existing ones where all dried out and crushed.

thanks
