It just replaces one of your valve covers. Just like in the picture on their website. The picture shows it installed on an XR-50 or some other really small bike. You probably can't see yours unless you remove some plastic. I don't have a 250ex, so I'm just guessing on it's location. Find your valve covers, and that's where it goes.
