So I did some research on head breather hose relocation, which lead me to go look at my bike. I pulled of the breather hose at the top of the head and found very fine dirt particles in the hose. I have not taken the valve cover off at all yet so I'm not sure if any dirt has collected in the head. I searched a lot but I was not able to find a definite answer as to what the best way is to reroute the breather hose on a 2010-13 yz450 is. So what is the best way to do it, and should I be worried about the dirt in my breather hose?
