Seized YZ125 - Replacing the Cylinder and Top End - Tear down and Install - 2 stroke dirt bike

My 2007 Yamaha YZ 125 blew off a radiator hose and overheated. The exhaust bridge in the cylinder cracked, the cylinder wall was scuffed, and the piston was scored. I tear down and rebuild the top end with a new cylinder and OEM top end kit. 2 stroke dirt bike top end rebuild.
