I hear a lot of people say very good things and very bad things about the 250F in general not just the YZ. I’m thinking about making the transition to 4stroke and found a good deal on a 08 YZ 250F. Owner says Rebuild has 20 hours on it. How often do these engines need rebuilt because I know it’s not cheap to do so and I live on a tight budget. Do you like your 250F ? Let me know your opinions and experiences thanks.
