I have a question about my wifes XR200. I know it's not a 650 but some of you may know. There is this strange little funnel shaped plastic canister attached to the frame. It has 3 half inch hoses attached to it. One connects to the crankcase, one to the airbox, and the other goes nowhere and is plugged. What is this thing? What does it do? And if I don't need it, how can I properly remove it?
