Description
Cylinder Naraku 180cc 63mm forged piston GY6 / Kymco AC - tuning cylinder for Kymco / GY6 152/157QMI 125/150cc 4-stroke scooters.
It is a top quality Big Bore tuning cylinder with 63mm bore. All necessary gaskets are included. More displacement, in this case 180cc, will give your engine considerably more power, torque and acceleration will get nicely boosted. If you want to improve performance even more, we recommend a tuning camshaft with longer valve timings and a tuning cylinder head with larger valves and large combustion chamber. The cylinder can however be used with original head and original camshaft.
The cylinder comes with a top quality forged piston - hard-wearing, low-friction, with a raised skirt for higher compression.
Note: the crankcase opening for the cylinder base will not be big enough for this cylinder, the opening must be machined to create sufficient space for this big bore cylinder. Please follow the instructions given in the manual!

How to Install a cylinder on a scooter, motorcycle or moped
The cylinder or cylinder kit is the heart of the engine on scooters, motorcycles and mopeds. It consists of a cylinder, a piston with piston ring(s), a cylinder head and gaskets needed for installation.
The service life of a cylinder depends on whether it has been fitted correctly.
Tuning Level: Sport
We categorize our products into different performance levels Original, Sport, Racing and High End , so that our customers can choose the right parts for their setup. It is really important to combine parts that belong to the same tuning level, this is especially true for cylinders, crankshafts and exhausts.
The products listed under Sport yield better performance than Original parts. They may have technical differences, such as the use of higher quality materials, a larger displacement or a performance-enhancing design. They are suitable for everyday use and have a long service life.
