GY6 50 Big Bore 52.4

GY6 50 Big Bore 90cc 52.4 Kit Complete (88cc??)

Scootertronics prefers the NCY kits with large valves and larger exhaust port for better air flow more top end and torque at take off with larger exhaust header.

QMB139 GY6 49cc 90cc Big Bore Kit with Air Filter Main Jet 95 Cylinder, Head, Cam Shaft, Gaskets

Scootertronics offers the Naraku Kit at 52.4 which is .4 of a mm bigger than our NCY kit, I do not consider this kit to be 90cc four stroke. To make the kit a complete upgrade that will allow the best torque because that is what we need the most to get the power to the wheel a cam shaft and air filter plus jets are included.

  • Naraku Product that comes complete with
  • Naraku Cylinder Head
  • Naraku Cylinder
  • NCY Cam Shaft
  • Jet and Choice of Air Filter

    Kit can be used with stock carb or our 24mm carb upgrade which you will need manifold and spacer to make work correctly

    Stock pipe can be used and stock variator , we do suggest upgrades here also just make sure the belt, weights and clutch are not worn out or you will not enjoy your new found power
