So I just changed the oil in my 2013 yz450f and 1 or 2 laps in my bike just smelled terrible of burning oil. I got off it, let it cool down and tried it again and same thing. My buddy that was riding behind said he could smell it too and it was really strong. I looked in the sight glass and the oil was already black, and there was no smoke coming from it. Any ideas on what it could be? I'm not going to ride it til I get it figured out for sure
