Give your GY6-based scooter some serious power with this 171.3cc bolt-on kit for most 125\/150cc GY6 engines. To our knowledge, this is the only 61mm cylinder kit for the GY6 engine that exists in the USA. With most 61mm cylinder kits, you have to cut the engine cases somehow to fit them (cylinder skirt OD: 65mm). This is not the case with the NCY 61mm 171cc Big Bore kit (cylinder skirt OD: 62.7mm). It also features a lightweight reduced piston to increase performance even more. It is highly recommended to squirt this kit significantly rich due to its high-performance capability. To maximize performance and efficiency, it is also recommended to get our large 61mm valve head\u003c\/span\u003e \u003cspan class=\"NormalTextRun SpellingErrorV2Themed SCXW201482318 BCX8\"\u003e.\u003c\/span\u003e \u003cspan class=\"NormalTextRun SCXW201482318 BCX8\"\u003eSome stock heads may not fit.\u003c\/span\u003e\u003c\/span\u003e\u003cspan class=\"LineBreakBlob BlobObject DragDrop SCXW201482318 BCX8\"\u003e\u003cspan class=\"SCXW201482318 BCX8\"\u003e \u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e \u003cbr class=\"SCXW201482318 BCX8\"\u003e\u003cspan data-contrast=\"auto\" lang=\"FR-CA\" class=\"TextRun EmptyTextRun SCXW201482318 BCX8\" xml:lang=\"FR-CA\"\u003e\u003c\/span\u003e\u003cspan class=\"LineBreakBlob BlobObject DragDrop SCXW201482318 BCX8\"\u003e\u003cspan class=\"SCXW201482318 BCX8\"\u003e \u003c\/span\u003e\u003cbr class=\"SCXW201482318 BCX8\"\u003e\u003c\/span\u003e\u003cstrong\u003e\u003cspan data-contrast=\"none\" lang=\"FR-CA\" class=\"TextRun SCXW201482318 BCX8\" xml:lang=\"FR-CA\"\u003e\u003cspan class=\"NormalTextRun SCXW201482318 BCX8\"\u003eRequires minimum bore clearance of 62.9mm\u003c\/span\u003e \u003cspan class=\"NormalTextRun SCXW201482318 BCX8\"\u003eor\u003c\/span\u003e \u003cspan class=\"NormalTextRun SCXW201482318 BCX8\"\u003eboring and machining is required.\u003c\/span\u003e\u003c\/span\u003e\u003c\/strong\u003e \u003cspan class=\"LineBreakBlob BlobObject DragDrop SCXW201482318 BCX8\"\u003e\u003cstrong\u003e\u003cspan class=\"SCXW201482318 BCX8\"\u003e \u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\n \u003cp\u003e\u003cspan data-mce-fragment=\"1\"\u003e\u003cspan class=\"LineBreakBlob BlobObject DragDrop SCXW201482318 BCX8\"\u003eNCY 61mm 171cc Cast Iron Cylinder Kit with Cast Aluminum Piston.
