Review on 🛵 GY6 Engine Rebuild Kit 150cc Big Bore Cylinder Head Chinese Scooter - GOOFIT 57.4mm Bore Cylinder Kit by William Fowler

The only thing I can say about this product is that the price was good. Unless you are very knowledgeable about engines, these products will not come ready-made. Molded cast, not trimmed or feathered. Comes with valves installed, but you will need to disassemble the valves that are not seated. Do not just assemble a trial actuator as the valves will never close. Customer service is a joke with no understanding of their products. no one ever picks up the phone number.
