:confused: I posted a message a few days ago about oil in my 400ex airbox. I came to the conclusion the oil was flowing in through my crankcase breather. I thought the oil was overfull, but I have cleaned the crankcase breather out twice and the oil level is in the middle between low and high. About 3/8 inch of oil was in my crankcase breather after about a 10 minute ride. It is no longer flowing into my airbox but why is it still going up into the crankcase breather? It runs very strong but I am scared to ride because of this unusual problem. Please help I need to ride!!!
