oil in airbox?
I have my 2000 300ex with hmf slip-on, 130# jet, Big Gun rev box, uni air filter and the rest is stock. Well when I was washing her down I noticed in the airbox drain tube on the bottom it was filled over half way with oil. I always keep her clean but dont clean that part as often. I emptyed the drain tube and cleaned really good and did 15min. worth of riding and had more oil in drain tube (not alot but enough to cover bottom). The airbox itself was clean inside, the air filter is new. Could this be from excessive air filter oil? But the air filter didnt look overloaded with oil to me. Any thoughts or help?
