DKIIGAME Electric-Start Wiring Harness Kit for 50cc–125cc 4-Stroke ATVs & Pit Bikes — Includes CDI, Coil, Rectifier, Solenoid

Complete electric-start wiring harness kit that replaces factory loom and ignition components for 50cc–125cc 4-stroke ATVs, pit bikes, go-karts and scooters.

This DKIIGAME kit bundles the wiring harness and essential electrical parts you need to restore or upgrade an electric-start engine on small off-road vehicles. The set includes the main wiring loom plus coil, CDI, rectifier, solenoid/relay and keyed ignition switch so you can swap a damaged or incomplete electrical system without sourcing multiple parts. It’s designed to fit popular 50cc, 70cc, 90cc, 110cc and 125cc 4-stroke models and simplifies installation with pre-terminated connectors and labeled leads.

How will this wiring harness fit my 50cc–125cc vehicle?

The loom is made to match common connector layouts used on small 4-stroke ATVs, pit bikes, scooters and go-karts. Compare your existing harness to the product images to confirm plug types and lead routing before ordering.

• Compatible with 50cc, 70cc, 90cc, 110cc and 125cc 4-stroke engines
• Designed for models like KLX-style, Coolster and many generic quads
• Pre-terminated connectors for coil, CDI, rectifier and ignition switch
• Works for electric-start conversions and factory replacements

What components are included and why they matter?

This kit contains all the primary ignition and charging parts commonly needed when an electric-start electrical system fails. Having matching components reduces troubleshooting time and helps ensure each element communicates correctly with the engine.

• Complete wiring loom/loom harness for routing power and signals
• Ignition coil with lead for spark delivery
• CDI box (ignition control) matched to 4-stroke timing
• Rectifier for charging the battery and stabilizing voltage
• Solenoid/relay and keyed ignition switch for reliable starting

How difficult is installation and what tools will I need?

Installation difficulty ranges from moderate to easy for someone familiar with small engine wiring. Basic hand tools and a multimeter for verifying voltage and continuity will speed the job; follow wiring diagrams and match the connectors visually before powering up.

• Common tools: pliers, screwdrivers, adjustable wrench and zip ties
• Recommended: multimeter to test connections and charging output
• Mounting hardware typically reuses factory screws and clips
• Allow time to compare and route wires to avoid chafing or shorts

What should I check before ordering to avoid returns?

Confirm that the connector shapes, pin counts and general routing of your current harness match the pictures provided. Inspect the old harness layout and note any model-specific brackets or sensor plugs not shown in the kit.

• Compare the kit photos with your existing loom for connector matches
• Verify your engine is a 4-stroke model within the stated displacements
• Ensure the keyed ignition and solenoid placement align with your frame space
• Contact seller support if unsure—response available within 24 hours

Who this is for: This DKIIGAME wiring harness kit is aimed at DIY mechanics, hobbyists and small-vehicle owners who need a full replacement electrical package for 50cc–125cc 4-stroke ATVs, pit bikes, go-karts, scooters and buggies. It suits anyone rebuilding an electric-start system, repairing damage after a crash or swapping incompatible parts, and it’s especially useful when you prefer a single, matched set of ignition and charging components instead of sourcing items individually.
