I have a 2016 X-Fusion Metric R and even after letting all the air out it doesn't compress more than 80mm out of the 180mm. I have taken it apart when it happened before and the thing that got stuck was the rebound damper. I messed with it and got it to work again, it worked perfectly, but now it's broken again. I think it might have something to do with the rebound air chamber and oil getting into it, but I have no idea. Does anyone know what's happening here and how I should fix it?
