EOPOAYI 3-Bolt Starter Motor Kit for 50–125cc ATVs & Go-Karts — Solenoid, CDI, Spark Plug

If your quad, pit bike or go-kart won’t turn over with the electric start, this kit provides the common mechanical and electrical parts needed for a direct swap. The package bundles a compact 3-bolt starter motor with matching solenoid relay, CDI, spark plug and basic fasteners so you can remove a worn unit and install a like-for-like replacement without fabricating mounts.

Will this starter fit my ATV or go-kart model?

Compatibility covers many popular Chinese 4-stroke small-vehicle models in the 50–125cc range. The critical requirement is a 3-bolt mounting pattern; confirm the starter on your machine uses three bolts rather than two before ordering.

• Fits many Taotao and Coolster 110cc/125cc models and lower-displacement 50/70/90cc variants.
• Also used on brands like SSR, Roketa, Kazuma, Vitacci, Icebear, Loncin, Baja and similar Chinese-built quads and pit bikes.
• Cross-references include popular model codes and engine families often found on utility and recreational ATVs.

How easy is the installation for someone doing basic mechanical work?

The kit is intended for straightforward replacement work and includes the essential small parts to fasten and connect the assembly. No drilling is required when replacing a 3-bolt starter with the same mount pattern.

• Comes with three mounting screws and a wrench to speed basic installation.
• Plug-and-play electrical connections for the solenoid and CDI in most direct-swap situations.
• Designed to remove the old starter and bolt the new one in place, assuming identical mounting and connector types.

What performance and durability features does the starter offer?

The starter motor is built to provide strong cranking force for quick starts and is manufactured from durable components to resist normal wear. It’s tested to deliver reliable service life under regular recreational use, but longevity depends on proper installation and electrical system condition.

• High-torque design to help turn 4-stroke engines efficiently.
• Durable housing and internal parts for routine riding and starting cycles.
• Includes solenoid relay and CDI to help ensure the starter, ignition, and control circuits work together after replacement.

What is included in the kit and what should I check before purchasing?

The kit supplies the starter and related small components so you have the main items needed for a typical swap. Before buying, verify your machine’s mounting pattern and wiring connectors match the parts provided.

• Included: 1 starter motor (3-bolt), 1 starter solenoid relay, 1 CDI box, 1 spark plug, 3 screws, 1 wrench.
• Confirm your vehicle uses a 3-bolt starter pattern; this kit will not fit 2-bolt starters without modification.
• Inspect existing connector types and battery/ground condition for best results after installation.

Who this is for: Riders, backyard mechanics and fleet maintainers who own small-displacement Chinese 4-stroke ATVs, go-karts, or pit bikes and need a compact, ready-made replacement starter assembly. It suits people seeking a direct-swap option with bundled hardware and ignition components, provided the vehicle uses a 3-bolt mounting pattern. If you’re unsure about fitment, compare your current starter’s bolt layout and connector style to the kit or contact the seller for assistance.
