Hello thanks for looking at my items for sale. You are bidding on the engine in the pictures. Its off a 2004 rmz 250f . It may fit other years as well please check with your local dealer to be sure. I was told it was in good running condition but could use a valve adjustment. I never started it because it didnt have a carb. It did seem to have good compression. If you have any questions please feel free to send me a message. Thanks Nate
