I just parked the 14 YZ450 and noticed some thick blue oil like substance on the stand as I was getting ready to throw it on. I wiped it up so I don't have a pic to show but further investigation shows where it ran down the side of the cylinder from just under the valve cover gasket. I didn't pull the tank or airbox so I'm not sure if there is any on top of the valve cover or not. Any ideas what this could be? I guess worth noting is that I have changed the air filter and the filter oil I'm currently using is red in color. Bike has about 4 hours on it.

It's probably your air filter oil.

As in from the factory filter? Do they come with blue filter oil?
