Glixal GY6 80cc Big Bore Cylinder Kit 47mm — High-Performance Complete Rebuild Kit

Glixal ATMT1-008 is a complete high-performance 47mm big-bore rebuild kit that converts GY6 50cc engines to an 80cc specification for stronger acceleration and higher top-end potential.

Designed as a direct upgrade for many Chinese-made GY6-style scooters and small ATVs, this all-in-one cylinder kit supplies the core components you need to increase displacement and improve engine responsiveness without hunting down individual parts. The set is built to fit popular makes like Jonway, JMSTAR, Roketa, Sunl, Tank, Peace, and TaoTao, and includes precision-machined pieces and OEM-matching gaskets so installation is straightforward for someone familiar with small engine rebuilds.

How does the Glixal 47mm big-bore kit change engine performance?

Increasing cylinder bore from the factory size to 47mm raises the engine’s swept volume to about 80cc, which typically yields stronger low-end torque and improved throttle response. The kit’s matching piston, rings and port fittings preserve compression and flow for an efficient upgrade when tuned correctly.

• Raises displacement to approximately 80cc for better acceleration.
• Includes quality piston and rings to maintain compression and sealing.
• Matched studs and gaskets to preserve intake and exhaust flow.

What parts are included and why does that matter?

This Glixal kit arrives as a complete rebuild package so you won't need to source separate components that might not be compatible. That reduces installation time and the risk of mismatched hardware causing leaks or poor performance.

• Cylinder, piston, piston rings, piston pin and clips — core rebuild items.
• Valve oil seal and tensioner gasket to protect valvetrain and timing parts.
• Intake & exhaust studs, exhaust nut, and all necessary gaskets for leak-free assembly.

Will this kit fit my scooter or ATV?

The kit is engineered for GY6-style 49–60–80cc engines commonly found in many Chinese scooters and small ATVs. Fitment is broad, but you should verify your engine uses a 47mm bore upgrade path and GY6 bolt pattern before purchasing.

• Compatible with many Jonway, JMSTAR, Roketa, Sunl, Tank, Peace, and TaoTao models.
• Intended for GY6 49–60–80cc engine families using a 47mm piston bore.
• Check crankcase and head clearances and carburetor jetting when upgrading displacement.

How difficult is installation and what should I prepare?

Installation requires basic engine rebuild skills, common hand tools, and a clean workspace. If you’re comfortable removing the cylinder head, diagnosing timing/valvetrain clearances, and re-jetting the carburetor, this kit is a practical DIY upgrade; otherwise consider professional installation.

• Requires removal of head, cylinder, and existing piston assembly.
• Expect to check ring end gaps, torque specs, and timing clearances.
• Carburetor rejetting and fresh oil change recommended after install.

Who this is for: Riders who want a reliable, parts-complete route to more power on GY6-style 50cc scooters or small ATVs — from hobbyists rebuilding a daily commuter to small-shop mechanics upgrading multiple machines. This Glixal kit is best for users prepared to verify fitment and perform or arrange a competent installation; it’s not a plug-and-play speed module but a proper engine rebuild component set aimed at lasting performance when assembled and tuned correctly.
