DKIIGAME Electric Start Wiring Harness Kit for 50–125cc 4-Stroke ATV Pit Bike — Complete Loom with CDI, Coil, Solenoid

DKIIGAME Electric Start Engine Wiring Harness Kit is a complete replacement loom with coil, CDI, solenoid, relay and ignition parts for 50cc–125cc 4-stroke ATVs, pit bikes, go-karts and scooters.

This plug-and-play wiring harness bundle provides the main electrical components needed to restore electric start and ignition systems on small four-stroke recreational vehicles. Designed to match common OEM layouts for 50cc, 70cc, 90cc, 110cc and 125cc engines, the kit includes the wiring loom, coil with lead, CDI box, rectifier, solenoid, key/ignition switch and related connectors so you can replace a damaged or missing harness without sourcing multiple parts separately.

How do I know this harness fits my 50–125cc ATV or dirt bike?

Compatibility is determined by the engine frame connector layout and the number of wires on your existing harness. Compare your current electric start wiring system to the photos and pin counts in the product listing to confirm a match before ordering.

• Fits many 4-stroke 50cc, 70cc, 90cc, 110cc and 125cc models
• Common fits: small ATVs, pit bikes, go-karts, scooters and buggies
• Match plug shapes and wire colors to your old harness for a correct fit

What components come in the complete replacement kit?

The kit supplies every primary electric-start component so you do not need separate purchases. Each piece is prepared to integrate with the included wiring loom and to replace the usual failure points on small-displacement engines.

• Wiring loom harness with connectors for switches and engine components
• Ignition coil with lead, CDI ignition module and rectifier/regulator
• Starter solenoid, relay and keyed ignition switch for secure starting

How difficult is installation and what tools will I need?

Installation is typically straightforward for anyone comfortable with basic motorcycle or small-engine work. You will route the new harness along the frame, reconnect the matching plugs, mount the coil, CDI and rectifier, then secure the solenoid and ignition switch.

• Required tools: basic socket set, pliers, wire cutters, electrical tape
• Allow 1–2 hours for removal of the old harness and fitting the new one
• Double-check connectors and ground points before first power-up

What should I test after fitting the new wiring harness?

After installation, verify power, ignition timing, charging and starter response before riding. A quick systematic check reduces troubleshooting time and confirms the harness and components are functioning as expected.

• Confirm battery voltage and ignition switch continuity
• Check spark at the plug and starter operation via the solenoid
• Verify charging output from the stator/rectifier while running
