Yup. The crank case breather dumps into the engine in the airbox inside the air filter. A lot of us guys and gals have rerouted the crankcase breather to a dedicated container. Some believe it works and some don't. Me personally, I'd rather have oil dump into the container than into the engine. Just my preference though. Like I said, I can link you to some picks if you want. Just PM me, 'cause I'm not the best checking up on old posts.
