    Description

    This is a really nice survivor 1978 YZ250E cylinder & head. It correctly fits & works on the 1978 & 1979 YZ250 & the 1979 IT250F. No missing, broken, or cracked fins. All threads are good on the studs as well as the intake bolt hole threads. Cylinder wall has no catastrophic damage. No grooving. Showing some piston skirt wear on the cylinder wall below the intake from the piston rocking in the bore. Currently at 70.50 mm, .50 mm over standard bore. The piston in it is included but is not usable. Should probably be taken up to 70.75 mm over bore to make the tolerances as new. There is lots of moto life left in this cylinder. No damage to the head dome. No bent or broken head fins. Spark plug threads are good. You will be getting all that is pictured. This weighs 15 lbs boxed properly so shipping is gonna be expensive for me. I will be boxing this up with styrofoam on all 6 sides so the shipper can not damage this in transit to you. My heavy vintage dirt bike parts always get boxed properly so they ship safely. Check out my other listings. I ship worldwide.
