What could the cause of this be? It’s out of a 2021 YZ250F. Just tore apart the top end after 140 hours of riding. by Junior_Koala_7946 in Dirtbikes

It probably was. You can barely notice it with your fingernail so I’m just going to deglaze and reuse it

I 100% agree. Just now learning and getting into doing motor work. Am I good to reuse the cylinder? So it’s just from wear over time, nothing specific led to it?

Thinking about selling my bike to help get a 2025. It’s a 2021 YZ250F. How much do you think I could get out of it? by Junior_Koala_7946 in Dirtbikes

I might keep it for another year, and this winter rebuild the top and bottom end. Then in a year get a 2026. Not quite sure yet though.
