Complete cylinder head for GY6 125cc 152QMI engines. Unlike many other available cylinder heads, this is a complete head. That means: valves, valve springs, valve shaft seals etc. This head is ready to install, with no need for grinding valves or fumbling with springs, or specialist tools. Dispatched ready to accept SLS. Delivery as shown.

Please note: If purchasing this kit for the Sym 125cc scooters, please ensure your engine is the GY6 version (cylinder head stud holes have a distance of 63mm hole to hole, outside to outside measurement).
