Restore your engine's heart with the Universal Parts 6-Pin AC CDI. As the primary controller for your vehicle's spark and timing, this Capacitive Discharge Ignition (CDI) unit is engineered to deliver a consistent, high-energy pulse to your ignition coil. Designed specifically for AC-powered (Alternating Current) systems, this unit is a direct-fit replacement for the "Honda-style" horizontal 4-stroke engines found in millions of pit bikes, ATVs, and mini-choppers.

Technical Performance Features

• AC-Powered Reliability: Optimized for standard stator-fired ignition systems, ensuring dependable starting even with a low battery.
• OEM 6-Pin Configuration: Features the industry-standard "2/4 Split" connector (two plugs: one 2-pin and one 4-pin) for a secure, click-in installation.
• Heavy-Duty Resin Casting: The internal circuitry is fully potted in a vibration-resistant resin to protect against the high-impact conditions of off-road riding.
• High-RPM Timing Curve: Calibrated to provide stable timing across the entire powerband, from idle to wide-open throttle.

Comprehensive Fitment Guide

This CDI is a standard replacement for 50cc, 70cc, 90cc, 110cc, and 125cc 4-stroke horizontal engines, including:

Technical Specifications

• Ignition Type: AC (Alternating Current)

Mechanic's Note: CDIs are often the silent cause of a "no-spark" condition. Critical Tip: Verify your system is AC-powered before ordering. If your headlight only turns on when the engine is running, you likely have an AC system. Installation Tip: Ensure your Stator and Ignition Coil grounds are clean of rust, as a bad ground is the #1 cause of "blown" CDI units!

Mechanic's tip: Ignition coils often fail when hot, causing an engine to die after 15 20 minutes of riding. When replacing the coil, always install a fresh spark plug at the same time for best results. Also ensure the mounting point is free of rust and paint the coil bracket often serves as the electrical ground for the system.
