Just like the title states, it seems sand has been coming up through the breather (the one on the top of the valve cover of course) and entering my engine. The bike in question is an 2006 Yz450. I am currently tearing the engine down to inspect parts such as cams, carriers, cylinder walls, crank, and oiling system. Any info on how this would be possible would be helpful and, also i was wondering if anyone else has ever experienced this or heard of this?
