GY6 171cc / 172cc Builder Engine Kit (LONG CASE)

**PISTON RING GAPS HAVE BEEN MEASURED AND PRE-INSTALLED ONTO THE PISTON, THEN INSTALLED INTO THE CYLINDER. DO NOT REMOVE THE PISTON FROM THE CYLINDER, THIS CAN RESULT IN BENDING THE RINGS DURING RE-INSTALLATION, AND REQUIRE YOU TO PURCHASE NEW RINGS. THIS IS A LUXURY SERVICE YOU WILL NOT GET IN OTHER KITS. SLIDE THE PISTON DOWN JUST FAR ENOUGH TO INSTALL THE PISTON PIN, WITHOUT EXPOSING THE RINGS**

Do you want to build a 12:1 compression ratio 171cc (or as others call it a 172cc) with a fresh engine? No problem! This GY6 builder motor is perfect! This engine kit will come with nearly everything you need!
