This kit works with most GY6 125cc and 150cc Chinese engines with a 76mm bolt pattern. ---- An outstanding 180cc big bore cylinder kit for GY6 based 125/150cc engines. This cylinder kit fits on many air-cooled 4-stroke 125-150cc Kymco, REX and Keeway scooter engines and most Chinese import 125/150cc vehicles (scooters, quads and buggies).

Noticeable increase in power
Mostly in the low end, more torque and quicker off the line. I have two of the same quads, and the bored out one takes off faster and has more torque.
