Naraku cylinder kit 50cc

Cylinder Kit

NARAKU gained it's good reputation within the european market by producing high quality parts for vehicles with 139QMB and 139QMA 4-stroke engines and scooters with 1E40QMB 2-stroke engines.

The spare as well as the tuning parts are produced under strict regulations and become increasingly popular in the scooter market.

The range is characterised by a very good value-for-money ratio.

With the latest V.2 Cylinder kit series from NARAKU, we can offer a more advanced product. The piston has 2 additional CNC-machined oil grooves in the piston skirt, which collects engine oil to lubricate the cylinder bore and improve characteristics in extreme circumstances. The molybdenum coating aids the crucial running-in period. 2 oil recesses and a groove at each bearing point ensure the gudgeon pin is adequately lubricated. The 39mm cylinder from this kit corresponds to the power and dimensions of the original 50cc and is therefore road legal. Suitable for all GY6 50cc Chinese-built 4-stroke engines. This cylinder kit is much more affordable than to buying original spare parts individually. The quality is also significantly better than the Chinese manufacturers Delivery contains:. Cylinder, piston, piston ring set with oil scraper rings, gudgeon pin, gaskets and circlips for the gudgeon pin. Please note: For Sym scooters this kit is only suitable for the GY6 139QMB engine version and not the XS1P139QMB, AV05W or AW05W engine or the Sym Symply 2 models
