Adorish Kick Start Gear Shaft Pedal Kit for GY6 49cc–50cc (139QMB) — CNC Aluminum Complete Replacement

When a worn or broken starter shaft, kick pedal, or idle gear leaves your scooter stranded, this all-in-one kit provides the components needed to get the engine turning again. Designed specifically for 139QMB/P139QMB (GY6-style) 49cc–50cc four-stroke engines, the set replaces the starter gear, start clutch, kick pedal, idle gear and spring with robust CNC aluminum parts for improved durability. It fits many popular scooter and ATV brands that use the GY6 49/50 platform, but is not intended for 80cc models or Zuma 50cc machines.

How will this kit restore my scooter's kick-start system?

The kit supplies every mechanical piece that typically fails in a manual kick-start assembly: the shaft, pedal, starter gear, start clutch and idle gear plus the return spring. Replacing all worn parts together eliminates mismatched wear and prevents premature failure.

• Complete set replaces shaft, pedal, starter gear, start clutch, idle gear and spring
• CNC aluminum alloy construction reduces bending and wear compared with stamped parts
• Parts sized for 139QMB/P139QMB (GY6) 49cc–50cc four-stroke engines
• Direct-fit replacement—no machining required for compatible models

Which models and engines are compatible with this replacement kit?

This assembly is engineered for the common GY6 49cc and 50cc four-stroke variants (139QMB / P139QMB). It is a typical fit for many Chinese-made scooters and ATVs that use the GY6 platform such as models from Roketa, Taotao, Jonway and similar manufacturers.

• Fits 49cc and 50cc 139QMB / P139QMB (GY6-style) four-stroke engines
• Compatible with many Roketa, Taotao, Jonway and other GY6-based scooters
• Not compatible with 80cc scooters or Yamaha Zuma 50cc
• Check engine code and part profile before ordering to confirm fit

How difficult is installation and what tools will I need?

Installation is straightforward for anyone familiar with basic scooter maintenance. The kit is intended as a direct replacement; typical steps include removing the old kick-start assembly, fitting the new shaft and gears, and securing the pedal and spring.

• Requires basic hand tools: sockets, wrenches, pliers and screwdrivers
• May need engine cover removal to access the starter shaft area
• Follow service manual torque specs when tightening fasteners
• Professional installation recommended if you’re unfamiliar with engine disassembly

What material and durability improvements does this kit offer?

Components are machined from CNC aluminum alloy, providing greater strength and resistance to deformation compared with lower-grade stamped or cast parts. That makes the assembly less likely to bend or strip under repeated use.

• CNC-machined aluminum alloy for improved rigidity and wear resistance
• Precisely cut gear teeth for consistent engagement and smoother start action
• Complete kit approach reduces risk from mixed old/new component wear patterns
• Includes return spring sized to restore reliable pedal return

Who is this for: The Adorish Start Gear Kick Start Shaft Pedal Kit is ideal for owners of GY6 49cc–50cc scooters and small ATVs who need a robust, direct-replacement starter assembly. Choose this kit if your kick pedal is loose or bent, the starter gear slips, or the start clutch has failed. It’s a practical option for DIY mechanics who want quality CNC components and for repair shops that service Chinese-built scooter platforms. Double-check your engine model (139QMB/P139QMB) before purchase to ensure compatibility.
