Description: NCY 61mm 171cc Cast-Iron Cylinder Kit with a Cast Aluminum Piston. Give your GY6 based scooter some serious power with this bolt-on 171.3cc kit for most GY6 125/150cc engines. As far as we know, this is the only 61mm cylinder kit for the GY6 engine that exists in the US. With most 61mm cylinder kits, you have to cut the engine cases in some way to make them fit (Outer Cylinder Skirt Diameter: 65mm). Not so with the NCY Cylinder 61mm 171cc Big Bore Kit (Outer Cylinder Skirt Diameter: 62.7mm). It also has a lightweight cut-down piston to increase performance even more. It’s highly recommended to jet this kit significantly rich because of its high-performance capability. To maximize performance and efficiency, it’s recommended to get our 61mm big valve head as well. Some stock heads may not fit.

NOTE: This NCY Cylinder 61mm Jug will NOT work on Genuine Buddy 125 (see NCY Part# 1100-1287). Also, please measure with a caliper GY6 crankcase bore (opening) for 62.7mm cylinder outer diameter sleeve need a minimum of 62.9mm bore clearance or boring and machining are required.
