OK here it is the very affordable quality made complete head piston with rings, gaskets and cylinder for 70cc upgrade for your GY6 50 139QMB engine. A performance cam and gear set are also included for complete engine upgrade please remember to do clutch and variator plus exhaust also.
This is a true 70cc and is the quality Scootertronics puts out the door with no piston problems or parts missing. Need more power see our 80/85 kits with cams and air and jets.
Great kit that puts you where you need to be in traffic and not holding things up.
