1999 99 Yamaha YZ250 YZ 250 OEM Cylinder Head Power Valve Piston Top End Motor

  

1999 Yamaha YZ250 Top End Assembly. This Top End Was Already Apart From The Engine When We Got It. So Unfortunately We Didn't Hear It Run.

The Cylinder Looks Good Inside With No Deep Scratches Or Grooves. Everything Looks Good All Around Except The Piston Is A Hair Too Big For The Cylinder. So It Will Need A New Piston. We Will Include The Piston Anyhow. This Top End Comes Exactly As Pictured With Everything Pictured. It May Fit Other Years & Models But We Only Guarantee It To Fit The Listed Model.
