Product Overview
This 4-piece ignition and charging system kit is designed for the world’s most common GY6 4-stroke engines, providing a complete solution for no-start, weak spark, charging failure, or intermittent electrical issues.
Instead of replacing components one by one, this kit renews the entire high-voltage ignition path and voltage regulation system, ensuring strong spark, stable charging, and dependable starting.
All components are manufactured to meet or exceed OEM standards, using high-grade copper windings and heat-resistant polymers to withstand the high-temperature environment of rear-mounted scooter engines.

A very good price and it all works as it should.
Ok product
I used most of this kit to get a neglected 150cc going again. Worked great.
Awesome
Good
Just needed the ignition coil, but can never complain about spare parts. Coil works great. Great value for the money.
Perfect except for the regulator had to trim a little off
Great deal!
