HIAORS 4 Wire Pin Ignition Key Switch Set

The 4 pin ignition switch is designed for common Chinese ATVs and quads in the 50cc to 150cc range. It supports models from TaoTao, Coolster, Apollo, Hawk, Buyang, Roketa and Sunl, making it a versatile replacement for many Chinese made 4 wheelers. The unit highlights a copper-contact interior for reliable conductivity and a durable exterior built to resist frequent use and outdoor exposure. Compatibility lists include a wide range of ATA and 3050B style Coolster machines, Baja, Coleman and other brands, reflecting broad aftermarket support.
Key considerations: verify your model’s pin count and ignition wiring; copper contacts reduce resistance for stable performance; durable build suits outdoor environments; compatibility breadth helps reduce the need for multiple variants.
4 Pin Ignition Key Switch 4 Wire For Chinese ATVs

This ignition switch supports many 50cc to 150cc Chinese ATV models, including TaoTao, Coolster, Apollo, Hawk, Buyang, Coolsport, Kazuma, Sunl, Roketa and more. It employs pure copper contacts in the interior for improved conductivity and lower resistance. A sturdy, durable design is emphasized to withstand frequent use and varying outdoor conditions, providing stable performance as a replacement or upgrade for older ignition setups in budget-minded builds.
Key considerations: check exact ATV model compatibility against your machine’s listing; ensure wiring harness matches the 4-pin configuration; copper contacts offer better electrical reliability in variable temperatures.
FVRITO PZ20 Carburetor Kit

The PZ20 carburetor kit targets a broad set of 50cc–125cc Chinese ATVs, including Tao Tao, Coolster, NST, SunL, Kazuma, Baja, Roketa, Buyang, Lifan and more. The kit is noted for compatibility with numerous 110cc and 125cc Coolster models (such as 3050B/3050C/3125 series) and various others used in Chinese mini bikes and dirt bikes. The kit is positioned as a replacement option to restore fuel delivery efficiency and throttle response for aging carburetors on small displacement engines.
Key considerations: confirm carburetor model compatibility with your engine and intake manifold; consider jetting changes for optimal performance; ensure accessories (gaskets, seals) are included or sourced separately if needed.
OEPUNAIKE Starter Solenoid Relay

The OEPUNAIKE starter solenoid relay is presented as a compatible replacement for a broad set of Chinese manufactured 125cc dirt bikes, 200cc go-karts, pocket bikes up to 150cc mopeds, and 4-stroke GY6 engines across 50cc–150cc classes. The product aligns with Roketa, Tao Tao, Sunl, Baja, and Roketa ATV models, among others, providing a key component for reliable ignition starts and electrical system function in budget builds and maintenance scenarios.
Key considerations: ensure the relay matches your engine’s amperage and terminal layout; verify the harness connector type; replacement timing can impact starting reliability in older machines.
DKIIGAME Solenoid Starter Relay

The DKIIGAME starter solenoid relay is marketed for a broad array of Chinese made 50cc to 125cc ATVs, dirt bikes, go-karts, and scooters with four-stroke GY6 engines. It supports popular brands including Roketa, Sunl, Baja, Kazuma, Coolster, Taotao, and Jonway, and also extends compatibility to older and higher displacement Honda, Kawasaki, Suzuki, and Yamaha equivalents in some listings. The product emphasizes wide replacement compatibility for multiple platforms, potentially simplifying parts stocking for a mixed fleet.
Key considerations: verify that the relay’s terminal arrangement and amperage fit your specific model; check for included mounting hardware and wiring adapters; consider stocking extra relays for a fleet or workshop needs.
Buying Guide: Key Purchase Considerations
- Model compatibility: Chinese made 4 wheelers span many brands and model years. Always verify exact fitment against your machine’s year, displacement, and ignition or carburetor model to avoid mismatches.
- Electrical reliability: components like ignition switches and solenoids rely on copper contacts and robust housings to resist corrosion and vibration. Look for copper contact interiors and durable casings for longer life in outdoor use.
- Quality vs. price: aftermarket parts can vary in quality. Reading user reviews, checking warranty terms, and comparing materials help balance cost with reliability for budget builds.
- Installation requirements: some parts require specific harness types, jets, or gaskets. Confirm what else you need beyond the listed item to complete a proper installation.
- Fleet considerations: for multiple machines, choosing parts with broad compatibility can simplify maintenance; however, ensure there is no compromise on fit for your most critical units.
- Maintenance and safety: regular inspection of ignition systems and carburetors reduces the risk of starting failures and ensures safe operation of the vehicle.
