9:00 a.m. to 6:00 p.m. (Mon.-Fri.) / 10:00 a.m. to 4:00 p.m. (Sat.)Kit de cylindre en fonte NCY 61 mm 171 cm3 avec piston en fonte d'aluminium. Donnez à votre scooter basé sur GY6 une puissance sérieuse avec ce kit boulonné de 171,3 cc pour la plupart des moteurs GY6 125/150 cc. À notre connaissance, il s'agit du seul kit de cylindres de 61 mm pour le moteur GY6 qui existe aux États-Unis. Avec la plupart des kits de cylindres de 61 mm, vous devez couper les carters du moteur d'une manière ou d'une autre pour les adapter (diamètre extérieur de la jupe du cylindre : 65 mm). Ce n'est pas le cas avec le kit NCY 61mm 171cc Big Bore (diamètre extérieur de la jupe de cylindre: 62,7 mm). Il dispose également d'un piston réduit léger pour augmenter encore plus les performances. Il est fortement recommandé de gicler ce kit significativement riche en raison de sa capacité de haute performance. Pour maximiser les performances et l'efficacité, il est également recommandé d'obtenir notre grande tête de soupape de 61 mm. Certaines têtes de stock peuvent ne pas convenir.
Nécessite un dégagement d'alésage minimum de 62,9 mm ou un alésage et un usinage sont nécessaires.
NCY 61mm 171cc Cast Iron Cylinder Kit with Cast Aluminum Piston. Give your GY6 based scooter some serious power with this 171.3cc bolt-on kit for most GY6 125/150cc engines. To our knowledge, this is the only 61mm cylinder kit for the GY6 engine that exists in the United States. With most 61mm cylinder kits, you have to cut the engine cases somehow to fit them (cylinder skirt outer diameter: 65mm). This is not the case with the NCY 61mm 171cc Big Bore kit (cylinder skirt outer diameter: 62.7mm). It also features a lightweight reduced piston to increase performance even further. It is highly recommended to squirt this significantly rich kit due to its high performance capacity. To maximize performance and efficiency, it is also recommended to obtain our large 61mm valve head. Some stock heads may not fit.
Requires a minimum bore clearance of 62.9mm or boring and machining is required.
