NCY GY6 150 61mm Cylinder Kit w/o head 62.5mm outer sleeve diameter.


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 it fit. Not so with this kit.


It also has a light weight cut down piston to increase performance even more. It’s highly recommended to jet this kit significantly rich because of its high performance capability. In addition, it’s recommended to get our 61mm big valve head as well. Some stock heads will not fit.


**NOTE: YOU WILL HAVE TO BORE OUT YOUR ENGINE TO COMPLETE INSTALLATION**


**NOTE: Not legal for use in California on pollution controlled vehicles. Check local laws before installing.**


**MADE IN TAIWAN**


**NOTE: Electrical, High Performance, Aftermarket items are non-returnable so please check photos and specifications before ordering.
