cylinder kit Naraku 150cc 57.4mm for GY6

Complete cylinder kit with all gaskets and small parts for fitting. This 150cc Naraku cylinder yields engine performance corresponding to the original cylinder of 150cc GY6 and Kymco AC engines. Thus ideal as an inexpensive replacement for a defective original cylinder. The cylinder kit can also be used to increase the performance of 125cc GY6 and Kymco AC motors. 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).
