Hello all, hopefully you guys can help me out. First off i have a 2002 cr250. When unloading my bike to go riding I knew something was off. The bike was sitting a few inches lower. So I sit on it, and its like a rock. No give at all. I think the rear shock might have blown but there is no oil leak anywhere. Could the nitrogen just leaked out over time? The bike seemed normal before i loaded it up. I'm not an expert on the rear shock so Any help is appreciated.
