PRO BAT Lifan Stator Kick-Start Wiring Harness Kit — 50–140cc 4‑Stroke Complete Ignition Set

PRO BAT Lifan Stator Kick Start Electrical Wiring Harness Kit is a complete kick-start electrical set—CDI, coil, spark plug, kill switch, magneto and harness—designed to replace or upgrade wiring on 50–140cc 4-stroke Chinese-engine dirt bikes.

This kit provides the core ignition and wiring components for kick-start-only small-displacement motorcycles and pit bikes. It fits popular Lifan-based engines and many Chinese makes such as Loncin, Zongshen and YX, offering an all-in-one replacement when the original stator, harness or ignition parts are damaged, missing, or corroded. The package includes a clear wiring diagram to guide installation, but professional assembly is recommended to ensure safety and reliable performance.

What parts are included and why do they matter?

The kit bundles the main electrical components needed to restore kick-start ignition: a 5-pin CDI, ignition coil, spark plug, kill switch, complete wire harness and magneto. Having matched parts packaged together reduces compatibility issues and simplifies replacements after electrical damage or during restorations.

• 5-pin CDI: manages ignition timing for spark generation
• Ignition coil: steps up voltage to fire the plug
• Spark plug: the final spark source for combustion
• Kill switch: safely cuts ignition on demand
• Wire harness & magneto: connects and powers the system from the stator

Will this kit fit my bike and engine model?

This wiring harness kit is built for 4-stroke kick-start engines in the 50cc–140cc range commonly used across many Chinese-manufactured bikes. It is specifically compatible with Lifan engines and generally fits Loncin, Zongshen and YX platforms, but connector shapes and routing can vary by bike model and year.

• Fits engine sizes: 50cc, 70cc, 110cc, 125cc, 140cc (4-stroke, kick start)
• Designed for Lifan and many Chinese engine makes (Loncin, Zongshen, YX)
• Check physical connector types and mounting points before installation
• Minor plug modifications or splicing may be required for some models

How difficult is installation and what should I watch out for?

Installation requires intermediate electrical and mechanical skill: you will route the harness, secure the magneto/stator, connect the CDI and coil, and verify the kill switch and spark plug wiring. An incorrect connection can prevent starting or damage components, so the included wiring diagram should be followed closely and a professional mechanic is recommended if you are unsure.

• Follow the provided wiring diagram step-by-step
• Confirm connector pinouts before applying power
• Secure all fasteners and insulate exposed wiring to prevent shorts
• Test ignition system on a bench or with the battery disconnected where applicable

What limitations or compatibility notes should I consider?

This kit supports kick-start-only configurations—there is no starter motor or battery-dependent starter wiring included. Some bikes may have different plug genders or additional accessories that require adapter wires. The seller recommends professional installation to avoid misassembly risks such as poor grounding or wiring faults.

• Kick-start only: not for electric-start conversions
• May need minor plug changes to match original wiring harness
• Proper grounding and insulation critical to avoid electrical faults
• Manufacturer not responsible for improper DIY installation damage

Who is this for: Riders, mechanics and small-shop restorers who own or service 50–140cc 4-stroke kick-start dirt bikes with Lifan-based engines will find this PRO BAT kit useful. It’s aimed at those replacing a damaged stator/harness, rebuilding a project bike, or swapping failed ignition components and who understand basic motorcycle electrical work or can hire a technician to perform a safe, correct installation.
