Ive noticed the 09 YZ450F racers dont have the oil breather running down the side of the frame. Where or what do they do with it and why?

The San Manuel team bikes simply turn the tube around and run it down behind the engine, and out near the carb vent hoses. They may or may not T it near the carb with a second leg of it running to the air box, I don't know.
