LEIMO KPARTS complete wiring harness for 50–125cc 4-stroke ATVs — stator, CDI, rectifier, ignition switch included

Complete electrical wiring harness kit for 4-stroke small-engine ATVs, including stator, CDI, rectifier, ignition switch with keys, solenoid, ignition coil, and spark plug.

This LEIMO KPARTS wiring loom is a full replacement electrics package designed for Chinese-made, electric-start upright 4-stroke engines from about 49cc to 125cc. The kit brings together the stator (magneto), CDI, regulator/rectifier, ignition coil, starter solenoid, multi-function switch, keyed ignition, and a spark plug so you can restore a non-functioning electrical system or build a clean install for a mini-quad, pit bike, go-kart or scooter. It’s built to match the common connector types and routing used on many KLX-style and entry-level ATVs, but it’s not compatible with GY6 mopeds or larger 200–250cc Zongshen/Lifan systems that use different stators or CDIs.

How will this kit simplify replacing a faulty wiring system?

Instead of sourcing individual parts from different suppliers, this single loom delivers every core electrical component needed to get an electric-start small ATV running again. The harness is pre-assembled to fit typical frame routing, reducing installation time and guesswork.

• All essential parts included: stator, CDI (5-pin AC), rectifier, solenoid, ignition coil, keyed ignition switch, multifunction switch, and spark plug.
• Pre-made connectors and grouped wires for straightforward plug-in connections.
• Designed for common Chinese mini-ATV wiring layouts to minimize custom splicing.

What engine types and models will this wiring harness work with?

This assembly is aimed at small, upright 4-stroke electric-start motors typically found on 49cc–125cc ATVs and quads. It fits many Chinese-manufactured machines, Kawasaki KLX-style mini quads, Coolster, Motowork, and similar models using compatible stators and CDI pinouts.

• Compatible: 50cc, 70cc, 90cc, 110cc, 125cc electric-start ATVs and pit bikes.
• Works with many mini quads, go-karts, scooters, and 4-wheelers using matching connector patterns.
• Not for: GY6 motorbikes or 200–250cc Zongshen/Lifan ATVs with different stators or CDI designs.

What should I check before ordering and installing this harness?

Match the magneto/stator photos and CDI pin layout to your bike before purchase; incorrect parts will not function and improper wiring can create hazards. Professional installation is recommended if you aren’t experienced with powersports electrics.

• Compare the magneto/stator image with your current unit for mounting and connector shape.
• Verify CDI is a 5-pin AC type and that ignition switch key match suits your needs.
• Use proper fusing and routing to prevent abrasion, heat exposure, or short circuits.

How do the included components improve reliability or maintenance?

Replacing worn or damaged electrical parts with a complete kit reduces failure points and restores factory-style function. The keyed ignition and upgraded multifunction switch provide secure, organized controls for everyday use.

• New stator and CDI reduce misfires and charging problems from aging components.
• Regulator/rectifier helps stabilize charging voltage to protect the battery and electronics.
• Solenoid and proper connectors improve starter reliability and reduce voltage drop.

Who is this for: This LEIMO KPARTS electrics bundle suits DIY mechanics, repair shops, and owners of small 4-stroke ATVs, mini quads, pit bikes or go-karts who need a full replacement loom for electric start systems between ~49cc and 125cc. If you’re restoring a machine with a faulty charging system or converting to an easier-to-service wiring layout, this kit gives the major electrical parts in one purchase—just confirm stator/CDI compatibility with your model and consider professional installation for safety and correct assembly.
