Eh everyone. Picked up my new to me 09 yz450 yesterday. Love it so far and hope it works just as good as it looks. I have noticed that there is a white substance coming out of one of the breather hoses, the biggest one on the front sprocket side. It smells like oil and i do not know what would cause this. The guy who i bought it from said he had the same problem and told me just to change the oil in the bike. I dont want this bike to frig up on me this soon as im only mowing lawns for an income haha. Im taking it to the shop to get a new rear tire and get the valves checked this week. What do you guys think would cause this to happen? Thanks.
