2010 YZ450F Breather reroute

I was told to use a PVC valve from a car that way it only lets the oil drain and nothing else in. The 1 way valve I think is the way to go. I'm going to the parts store today to see if I can find 1. I'll post later and let every one know

the PCV valve may not be a bad idea but it might be noisy?

PCV valves do not flow an adequate amount of air in their "open" mode.  You'll end up blow seals out. 

Thanks for the info I'm guessing just running it to the air box is the best solution there is a tech tip u can get from the Yamaha shop that give the the break down for it. The tech exchange # m-2007-009
