CYLINDER KIT 180CC

Beskrivning av CYLINDER KIT 180CC

Cylinder Kit 180cc 63mm forged piston for GY6, Kymco AC

180cc Big Bore Kit for GY6 based 125/150cc + engines

The bore is 63 mm, meaning the cases must be worked to accept the cylinder

The kit is compatible with all air-cooled 4-stroke 125-150cc Kymco engines (Maxi-scooters) and most Chinese import 125/150cc Scooters, Quads and Buggies with GY6 engines (not Kymco)

This cylinder kit can be used with the original cylinder head

For those who want even more, there is a camshaft with modified timing

The highlight of this Naraku cylinder kit is the forged pistons, which offer better durability and reduced friction

The raised piston skirt also ensures higher compression

This is not a simple installation. This requires precision work, as the clearances are pushed somewhat

If purchasing this kit for the Sym 125cc scooters, please ensure your engine is the GY6 version (cylinder head stud holes have a distance of 63mm hole to hole, outside to outside measurement)
