Naraku High-Performance Variator Drive Face Half Pulley Naraku HS-CNC V.2 for GY6, Kymco, 139QMB 4T 50cc Scooter Engines
V.2 is the latest version of the CNC-machined pulley from NARAKU. This enhanced version now allows you to mount the original variator fan wheel and carrier star him. (Fig. 2), the edge angle was revised again and combines a little more top speed with sufficient power. The CNC-machined running surface of the disc allows for a clean, low-vibration belt operation.
Unlike CNC machined pulleys for other types of engines, the HS CNC has teeth for the electric starter. This can be reused, saving tedious "clicking".
Number of Splines: 26
The toothing does however make the pulley more expensive. The original fan and carrier sprocket can still be used, but are not included. If required, please order separately.
