GREHUA Ignition Coil & CDI Box Kit for TaoTao 110–125cc ATVs — Plug-and-Play Repair Kit with Regulator and Solenoid

GREHUA ignition coil CDI box kit is a plug-and-play replacement set that restores spark, charging and starting functions on most Chinese 50cc–125cc 4-stroke ATVs, go-karts and pit bikes.

If your TaoTao or similar mini ATV has intermittent spark, a weak charge, or won’t start, this GREHUA kit bundles the common electrical parts that usually need replacing: a 5-pin AC CDI, starter solenoid relay, ignition coil with lead, a 4-pin voltage regulator/rectifier and two A7TC fuses. Each component is matched to fit many horizontal 4-stroke Chinese engines used in youth quads and small utility vehicles, enabling quick swaps without modifying the frame or drilling.

How will this kit fix no-starts and misfires?

Most no-start or intermittent-spark problems on small Chinese ATVs trace to a failed CDI, coil or faulty solenoid. Replacing these items together eliminates the usual electrical failure points and restores consistent spark timing and starting operation.

• New CDI stabilizes ignition timing and pulse delivery.
• Replacement ignition coil ensures strong, reliable spark to the spark plug.
• Starter solenoid relay restores proper starter engagement when present.
• Included fuses protect circuits during startup and operation.

Which models and engines are compatible with this GREHUA set?

This kit is designed for a broad range of Chinese-made mini quads, go-karts and small dirt bikes with 4-stroke horizontal engines. It fits many TaoTao models and a long list of peer brands — note it is not compatible with GY6 or CG-style engines.

• Fits TaoTao ATA-110 and ATA-125 series and many ATA variants.
• Works with Coolster, SunL, Kazuma, Baja, Roketa, Buyang and similar brands.
• Compatible with SSR, Lifan, Coleman, Xmotos, Vitacci and other 50–125cc models.
• Not suitable for GY6 or CG engine families — check engine layout first.

How difficult is installation and what tools are required?

Installation is straightforward and intended for DIY mechanics and hobbyists. Most fasteners are accessible and the connectors are plug-style, so you can replace the parts in minutes without cutting or drilling.

• All components are plug-and-play with matching pin counts.
• No permanent modifications or drilling required for standard installs.
• Typical tools: basic socket set, screwdrivers and pliers for connectors.
• Follow wiring diagrams or photos from the old parts to match connections.

Who is this for? This GREHUA kit is aimed at owners and home mechanics of Chinese-made youth and utility ATVs, go-karts, and small dirt bikes (50–125cc) who want a cost-effective, complete electrical replacement. If you’re troubleshooting hard-starting, intermittent ignition, or no-charge issues and your vehicle uses a horizontal 4-stroke engine, this set gives the core parts needed to diagnose and repair electrical faults without ordering multiple separate pieces. Always verify your vehicle’s engine type and connector pin count before ordering to ensure compatibility.
