Naraku Drive Face 114mm HS-CNC V.2 for 139QMB 49cc-50cc scooter engines. V.2 is the latest version of the CNC-machined drive face pulley from Naraku. This enhanced version now allows you to mount the original variator fan overlay and kickstart star him (See Fig. 3), 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 drive face pulley for other types of engines, the HS-CNC has teeth that perfectly aligned with the electric starter bendix. This can be reused, saving tedious "clicking" waste and wear. The perfect aligned teeth do however make the Naraku Drive Face most performance-driven in addition to its flashy red-race color.
