HIAORS GY6 Ignition Coil and Charging Kit for 50-150cc Scooters — Complete Coil, CDI, Regulator & Solenoid

HIAORS GY6 Ignition Coil Solenoid Relay Voltage Regulator kit is a complete ignition and charging module set designed to restore reliable spark, regulate charging, and replace worn electrical components on GY6-based 50–150cc Chinese scooters, mopeds, ATVs and go-karts.

This kit groups the core electrical parts you usually replace after hard use or intermittent starting problems: an ignition coil, a starter solenoid relay, a 6-pin AC CDI box, a 4-pin voltage regulator/rectifier and an A7TC spark plug. Each component is built to match the electrical layout found on many GY6 139QMB/139QMA/152QMI/157QMJ engines used by brands like Taotao, Roketa, Sunl, Jonway, Ice Bear and others, so you get plug-and-play style replacements that simplify troubleshooting and repairs.

How will this kit improve starting and throttle response?

By replacing the coil, CDI and spark plug together, you restore maximum spark energy and timing reliability. That produces quicker engine ignition at cranks and smoother acceleration as the combustion becomes more consistent.

• Stronger, higher-voltage spark from the new ignition coil
• Fresh CDI box to ensure reliable firing sequence
• New A7TC spark plug for optimal gap and conductivity
• Reduces misfires and hard-start symptoms

Will the voltage regulator and solenoid protect my battery and wiring?

The included 4-pin voltage regulator/rectifier converts AC from the stator into steady DC and keeps voltage within safe limits, while the starter solenoid relay provides a dependable switch for the starter circuit. Together they reduce the risk of overcharging and erratic electrical loads that can damage batteries and harnesses.

• Regulator maintains consistent charging voltage
• Rectifier function prevents AC leaking into the battery
• Starter solenoid offers reliable starter engagement control
• Helps prevent burned wiring and premature battery failure

Which scooters and engines does this set fit?

This kit is manufactured for GY6-format 4-stroke engines commonly labeled 139QMB, 139QMA, 152QMI and 157QMJ. It fits many 50cc–150cc Chinese scooters, ATVs and go-karts from manufacturers like Taotao, Baja, Roketa, Jonway, Vitacci, Kandi, Ice Bear and more.

• Works with TaoTao ATM50, CY50 series and Powermax 150
• Compatible with Baja, Roketa, Jonway, Vitacci, Sunl, Ice Bear models
• Suitable for many GY6-based 50–150cc quads and go-karts
• Check engine code (139QMB/139QMA/152QMI/157QMJ) to confirm fit

How durable and heat-resistant are these replacement parts?

Parts in the kit are constructed from materials chosen for heat dissipation and electromagnetic stability so they can withstand typical riding conditions. Proper installation and secure mounting further extend service life and maintain steady operation under load.

• Coil and CDI designed to minimize electromagnetic interference
• Regulator built for efficient heat dissipation under voltage load
• Solenoid rated for frequent starter cycles
• Pack includes a correctly gapped A7TC plug for durable ignition

Who is this for: This HIAORS kit is intended for DIY mechanics, scooter repair shops and owners of GY6-based 50–150cc Chinese scooters, ATVs and go-karts who need a coordinated set of electrical replacements to fix hard-starting, weak spark, charging issues or intermittent electrical faults. If your machine uses a GY6 family engine and shows ignition, starting or charging symptoms, this kit provides the common replacements required to diagnose and remedy those problems quickly.
