cylinder kit V.2 72cc for GY6, Kymco 50cc 2V
With the latest V.2 cylinder kit series from NARAKU we can offer a product that has been further developed in many details. Since a 4-stroke cylinder is in fact only a "bore", all attention was paid to the piston with its technical characteristics and compression. The piston now has 2 additional CNC-machined oil grooves in the piston skirt, in which engine oil collects to improve the necessary lubrication on the cylinder track and the emergency running properties. The piston was provided with an additional molybdenum coating especially for the sensitive running-in phase of the cylinder. The piston pin is better lubricated by 2 oil holes and 1 groove each in the bearing points of the piston pin. The compression ratio has been specially adapted to the needs of everyday use. The usual high manufacturing quality of NARAKU and very good performance are the hallmarks of this 47mm cylinder kit. The kit can be used with the original carburettor, but we recommend the adjustment of the main nozzle. All parts required for assembly are included in the scope of delivery.
