Hey guys, I have a very frustrating problem.
My valve cover gasket keeps blowing on my 07 wr450f. it blew a few weeks ago so I replaced it and adjusted my valve clearance while I was in there. I put it all back together and it blew again after about 2 hours of riding. This time when it blew, it blew hard. Both the half-moons came completely out and there was about a 5 foot cloud of grey smoke that shot out from the half-moons. I was able to put the valve cover gasket back in over lunch. I removed the breather hose and checked it for clogs, nothing. Just as a test i left the breather hose disconnected to ensure it was not clogged. 2 hours later it blew.
Im pretty frustrated. This is my first bike ever and i don't know how to fix it.
Do you guys have any suggestions?
