Compatible with quads/off-road vehicles/karts from 50 to 125 cc: Repair and upgrade kit including universal CDI ignition, high-voltage transformer and voltage regulator.

[Universal Small Vehicle Repair Kit] This three-piece electrical repair kit is specifically designed for ATVs (All-Terrain Vehicles), UTVs, go-karts, and small motorcycles with 50cc, 70cc, 90cc, 110cc, and 125cc engines. It includes: a CDI ignition module (controls the ignition timing), an ignition coil (high-voltage coil) (generates the high-voltage spark), and a voltage regulator (stabilizer) (stabilizes the charging voltage). This kit provides all the essential replacement parts for the ignition and charging system in a single set and is a cost-effective solution for common problems such as starting difficulties, stalling, and charging issues. [Three-in-One System Solution] CDI Ignition Module: Universally applicable, typically a 4-, 5-, or 6-wire AC CDI module, it handles ignition triggering and energy storage required for engine starting and running. Ignition Coil (High-Voltage Coil): It converts the low-voltage pulses generated by the CDI into high-voltage current (up to several tens of thousands of volts), thus creating a powerful spark at the spark plug that ignites the fuel-air mixture. Voltage Regulator (Voltage Stabilizer): It rectifies and stabilizes the alternating current generated by the magneto, providing a stable direct current (approx. 13.5 V to 14.5 V) for charging the battery and protecting electrical devices such as headlights from voltage spikes.
