The bike is a 2020.5 KTM 450SXF. It has 54 hours on it. I’m getting a ton of oil coming from the breather tube coming from the valve cover. I was at first thinking it was due to too much oil. That’s not the case, as I let the engine drain for 45 minutes to ensure all of the oil was out. I then filled it with the correct amount of oil (Motorex), started the bike, and about 45-50 seconds later, oil started coming from that breather tube. I looked in the sight glass to make sure the oil level was where it needed to be, and I noticed it started to create a white, milky substance to it. When paying very close attention, I can see a slight bit of steam/smoke coming from I believe it the crankcase vent. That isn’t normally alarming, as I see that on many bikes when I’m looking through photos I’ve taken. I’m not able to post a video, but here’s a photo of the oil sight glass. Anyone have ideas as to where I should start first?
