LEIMO KPARTS Complete Electrics Wiring Harness for 50–125cc ATVs — Stator, CDI, Regulator Kit (KLX-style)

Complete wiring harness kit that replaces the stator, CDI, rectifier, ignition, switch and connectors for many 4-stroke 50–125cc ATVs and mini quads.

This LEIMO KPARTS electrics kit bundles a full engine wiring loom with all major ignition and charging components to restore or upgrade electrical systems on Chinese-made 4-stroke ATVs, mini-quads and small dirt bikes. Designed for electric-start upright engines commonly found on 49–125cc machines, the set includes the parts you typically replace together when troubleshooting charging, ignition or starting problems. Before ordering, compare the magneto/stator image and connector shapes to your machine: this harness is not compatible with GY6 motorbikes or certain 200–250cc Zongshen/Lifan setups.

How will this kit fix charging or ignition issues?

Replacing the whole loom and its components clears compatibility problems caused by a worn stator, failing regulator, faulty CDI or damaged connectors. Installing the matched units reduces mismatch wiring and simplifies diagnostics because every major electric component is renewed in one package.

• Includes stator (magneto), rectifier/regulator and CDI matched to the loom
• New ignition coil and spark plug for consistent spark
• Solenoid relay and waterproof ignition switch for reliable starts
• Pre-terminated connectors fit many 50–125cc Chinese-style engines

Which machines and engine sizes are supported?

The harness covers a wide range of small 4-stroke ATVs and quads with electric start and upright Chinese-style engines. It’s commonly used on Kawasaki KLX-style mini bikes, Coolster, TaoTao, Motowork, go-karts, scooters and many generic 50cc–125cc models, but it’s not universal—match the magneto/stator picture and connector layout to your bike first.

• Compatible with many 49cc, 50cc, 70cc, 80cc, 90cc, 100cc, 110cc and 125cc ATVs
• Fits electric-start upright engines on quads, dirt bikes, go-karts and buggies
• Not compatible with GY6 scooter engines or specific 200–250cc Lifan/Zongshen stators

What exactly is included in the package?

You get a full wiring loom plus every common electrics part needed to operate the engine and charging system. That means fewer trips to parts stores and a cohesive kit where connectors and components are matched to work together out of the box.

• 1x complete ATV wiring harness loom
• 1x 5-pin AC CDI and 1x stator (magneto generator)
• 1x rectifier/voltage regulator and 1x solenoid relay
• 1x ignition coil with lead, 1x spark plug, ignition switch with two keys
• 1x upgraded multi-function handlebar switch

How should it be installed and maintained?

Professional installation is recommended to ensure safety and correct connections; improper assembly can cause electrical faults. After installation, check connections, routing clearances and secure any exposed wiring to avoid chafing and moisture entry.

• Compare the kit’s stator and plugs with your existing parts before fitting
• Route and secure the loom away from hot or moving parts
• Test charging voltage and ignition operation before final reassembly

Who this is for: This LEIMO KPARTS harness is aimed at owners and mechanics of small 4-stroke ATVs, mini quads and dirt bikes who need a one-stop electrical rebuild. It’s ideal when the stator, CDI, regulator or ignition components are suspected of failing and you prefer a matched set rather than piecemeal replacements. If your vehicle uses a GY6 or a 200–250cc Lifan/Zongshen stator, check compatibility carefully or seek the correct harness for those models.
