2001 Xr80r complete engine. Runs fine. Not sure on the hours on it as it’s an older bike and has had other owners before me. Expect normal wear that a 2001 engine would have. It’s not a new engine. I have videos of it running right before I pulled it. Comes with Chinese carb (that needs adjustment) and throttle cable. Only selling because I put a 120cc engine in the bike.
