Motorcycle Repair: oil in air filter box, vent hose, blowby

Question
my 350 honda today i took out air filter and it was full of oil....cleaned it and byin a new filter tomorrow just wanted toknow if it was a blowen engin or just to full of oil??????

Answer
Jeremy, Its possible that the engine is too full of oil and pumping in when running or the oil is too light and there is a lot of blowby in the crankcase and its blowing the light oil or vapors out the vent hose into the air box. Check the oil level and maybe just change to a heavier oil for now. See of this helps..
