shamofeng GY6 Starter Kit for 47–100cc Scooters & ATVs — Single-Wire 12V Motor with Bendix, Relay, Bolts & Wrench

shamofeng’s complete GY6 starter kit replaces worn single-wire starters to get 47–100cc Chinese 4-stroke scooters and ATVs turning over again.

This all-in-one starter motor combo is built for horizontal GY6 engines (139QMB/139QMA/147QMD family) used on many TaoTao, Jonway, Sunl, Roketa, Baja and similar Chinese-brand scooters, mopeds, ATVs and go-karts. The kit groups the electric starter, bendix (starter gear), solenoid relay, fasteners and a bent installation wrench so you have the parts and tool needed to repair a dead starter circuit without multiple orders.

Will this starter fit my 49cc, 50cc, 60cc or 100cc GY6 engine?

The shamofeng kit targets the single-wire starter pattern found on most GY6 horizontal 4-stroke engines from about 47cc up to 100cc. Before buying, compare your existing starter’s bolt spacing and overall shape to avoid fitment issues.

• Compatible engine families: 139QMB, 139QMA, 147QMD (horizontal layout).
• Bolt spacing: 70 mm (2-3/4").
• Overall length: 108 mm; CCW rotation, 10 teeth.
• Designed for single-wire 12V PMDD starter systems.

What’s included and why is this kit useful?

Instead of selling a single part, the package bundles the starter motor, replacement bendix, a solenoid relay, two bolts and an angled wrench. That combination addresses the most common failure points in starting systems so you can complete a repair in one session.

• Starter motor with single-wire lead for direct swap.
• Replacement bendix (starter drive) to restore gear engagement.
• Solenoid relay to replace a failing actuator or click-only starters.
• Two mounting bolts plus an angled wrench to reach tight mounting areas.

How difficult is installation and what tools do I need?

Installation is straightforward for anyone comfortable removing the engine side cover and electrical connections. The included angled wrench helps access confined spaces, but basic hand tools and safety precautions are required.

• Disconnect battery before starting work to avoid shorts.
• Remove cover, unbolt the old starter, swap the single-wire connection and torque bolts securely.
• Use the included angled wrench for tight mounting points; standard sockets may be needed for surrounding fasteners.
• Expect a 30–90 minute job depending on vehicle layout and experience.

Who is this for: This shamofeng starter kit suits DIY mechanics, small repair shops and owners of Chinese-brand scooters, ATVs or go-karts that use GY6 horizontal 4-stroke engines and single-wire starter systems. It’s a practical spare-parts set for anyone who wants a ready solution to no-crank or intermittent-start issues without sourcing individual components.
