DetailsImpressive power! So far, there haven’t been many cylinder kits for 4-stroke scooters to choose from, but NARAKU changes that.
The NARAKU Racing cylinder is the only cylinder available with a 52.4mm bore, and with its actual 89cc, it has the largest capacity among cylinders for the GY6 engines. The 89cc make for excellent torque and impressive increase in engine output. Other manufacturers tend to cheat about the effective swept volume, rounding up generously. In order to be able to compare cylinders and swept volume, you should always take the bore size as a basis.
Included in the kit are an optimized head with maximum intake and exhaust sizes, as well as a modified piston with coated rings. With this kit, you can simply replace the respective parts without any further conversions necessary. You can go on using your old carb, but make sure to adjust the jetting.
A more inexpensive alternative to the Racing cylinder is the sport cylinder with 47mm bore (effective displacement of 72cc).
