*by C***N on 10 May 2021*

Wonderful mod for any gy6 engine. My 80cc big bore moped now has tons of power and doesn’t bog down at certain speeds. This variator keeps the proper rpm all the way throughout the shift range. Takeoff is par none and low to mid speed acceleration is great. I can reach top speed and there’s still room for more shifting because I don’t feel the rpm increase unless I’m goin go downhill,
