That hose should be hanging down by the swingarm or around there. I'm don't think it has a special spot to go I just put it between the motor and swingarm.

I've go that and let me tell you it makes it ez to adjust the a/f screw when it is runing (which is when your supposed to adjust it)... Or you could get that one out and replace it with this http://www.ebay.com/itm/Easy-Adjust-Fuel-Mixture-Screw-fits-Keihin-FCR-carbs-MX-ATV-/290622125865?pt=Motorcycles_Parts_Accessories&hash=item43aa6db729&vxp=mtr but i'm not sure if that is actaully the one that will work on the ex but i know they make one that will work. Hope that helps you out some.
