I seem to have a chronic problem of always having a ridiculously large amount of oil in my air box. When I pull the side panel off to clean/replace the air filter, about a half a cup of oil comes flowing out. How does so much get in there? And where does it come from? Has anyone else had this problem? How do I fix it? I don’t think I have an oil leak anywhere, so how does it get out of my crankcase? Am I over filling? When I change the oil, I completely drain it and replace with 1 liter. I am pretty new too the whole off-road scene and I can’t remember this happening last summer. Any help would be much appreciated.
