Doing a big bore kit or cylinder kit on your GY6 engine is by far the best bang for buck. We have step by step install videos for installing a big bore kit into your GY6. In this video I will teach you what to look for. Do you choose a 61mm 171cc big bore kit? Or do you want to bore your engine cases and go with a larger cylinder kit like a 205cc or even a 232cc. What is the difference between forged pistons and cast pistons? Ill teach you the difference between 4032 forged pistons and 2618 pistons. I will guide you through the importance of choosing a big bore kit. Things people never talk about. Like should you purchase a drop in big bore kit for your gy6, do I need a ceramic coating and how to spot fake forged pistons. This video will not apply to gy6 50cc engines. This is for the GY6 A and B engines. both 54mm and 57mm stud spacing. also know as the QMJ157 gy6 or the QMI152 GY6.
