GREHUA GY6 Ignition Coil CDI Kit for 50–150cc Scooters Orange — Coil, CDI, Regulator & Spark Plugs

GREHUA GY6 Ignition Coil CDI Box kit is a plug-and-play replacement set that restores reliable spark, charging and starting for GY6-based 50cc–150cc scooters and small ATVs.

If your scooter or go-kart runs a GY6-style 4-stroke engine and is showing weak spark, intermittent charging, or hard starting, this GREHUA kit bundles the key electrical parts you need: an enhanced ignition coil, a 4+2 pin AC CDI box, a 4-pin voltage regulator/rectifier, a starter solenoid relay, and two spark plugs. Components arrive pre-wired and color-matched in bright orange for easy identification, and the set is engineered to match common Chinese moped and ATV models so you can replace worn electrical parts quickly.

What parts are included and what does each one do?

The kit contains the main ignition and charging components for a GY6 engine. Each piece addresses a specific electrical function so the motor runs, charges, and starts reliably.

• Ignition coil (enhanced orange) — steps up voltage to fire the spark plug for consistent combustion.
• 4+2 pin AC CDI box — times the spark precisely based on engine speed and position.
• 4-pin voltage regulator/rectifier — converts alternator output and protects the battery from over-voltage.
• Starter solenoid relay — reduces starter switch current and protects the starting circuit.
• Two spark plugs — ready spares for immediate installation.

Which models and engines is this GREHUA kit compatible with?

This replacement assembly targets GY6-style 49cc–150cc 4-stroke engines used across many Chinese scooter, ATV and go-kart brands. It fits vehicles that use 139QMB/139QMA/152QMI/157QMJ platforms.

• Common scooter makes: Tao Tao, Roketa, Jonway, Ice Bear, Vitacci, Peace Sports, Kandi, Baja.
• Model examples: Tao Tao ATM50-A1, Thunder 50, VIP Future, Roketa 50, Baja SC50.
• Also fits: select Tomberlin Crossfire 150R, Hammerhead GTS 150, small ATVs and 150cc go-karts.

How easy is the installation and what will I need?

Installation is designed to be straightforward: the kit is plug-and-play with no drilling or advanced tools required. Most users can complete the swap with basic hand tools and a few minutes of time.

• Remove the old coil, CDI, rectifier and solenoid, then plug in the new parts.
• Check connector orientations and secure grounds; tighten fasteners to prevent vibration loosening.
• Minimal wiring or splicing required when matching factory harness plugs.

What performance or reliability changes should I expect?

Replacing aged ignition and charging components typically restores consistent spark timing, steadier charging behavior, and cleaner starting. This kit focuses on dependable function rather than altering engine tuning.

• More reliable ignition across RPM range thanks to the matched coil and CDI combination.
• Improved charging stability with the regulator/rectifier protecting battery life.
• Lower start circuit stress because the starter relay reduces switching current.

Who is this for? Mechanics, DIY scooter owners, and fleet operators working with GY6-style 4-stroke engines will find this GREHUA kit useful when diagnosing weak spark, charging failures, or starter problems on 49cc–150cc scooters, small ATVs and go-karts. If you own compatible brands like Tao Tao, Roketa, Baja, Jonway, Ice Bear or Kandi and want a full replacement of the core ignition and charging components in one purchase, this set provides the parts needed to get the vehicle back on the road with minimal fuss.
