The OEM XR70 and CRF70 cylinder head will work with this big bore kit along with the OEM carburetor and all other remaining components. Basically, you pull the old cylinder off along with the piston and put this in its place, adjust fuel delivery a bit and you're all set for more power! No other parts are required to get up and running, it's all in the box.
