Retepif GY6 Starter Motor & Relay Solenoid 9-Tooth for 50cc–250cc 4-Stroke Scooters ATVs – Complete Drop-In Kit with Hardware

Retepif GY6 starter motor with relay solenoid is a complete drop-in replacement assembly for 4-stroke GY6 engines (9-tooth) used on 50cc–250cc scooters, ATVs, go-karts and similar vehicles.

If your vehicle won’t crank or the original starter has failed, this kit supplies a ready-to-install motor plus starter relay solenoid and mounting hardware compatible with many popular GY6-based models. It replaces several OEM part numbers and is intended for 4-stroke GY6 engines; it is not compatible with 49cc (GY6 49cc) variants. The package includes the starter motor, relay solenoid, screws, spark plugs, wrench tools and zip ties so you can complete the swap without extra parts.

How will this starter motor fit my vehicle?

This Retepif unit is built for common 4-stroke GY6 configurations used in scooters, mopeds, ATVs, go-karts and dune buggies. Before purchasing, verify the teeth count (9) and your OEM part number to ensure compatibility. The item replaces several OEM references and mounts directly in most applications without drilling.

• Fits 50cc, 150cc, 200cc and 250cc 4-stroke GY6 engines.
• Not compatible with GY6 49cc models—confirm engine size.
• Replaces OEM numbers 35850-286-007 / -027 / -017 and 35850-375-000.
• Plug-and-play installation on many Taotao, Baja, Roketa, Jonway and Coolster models.

What tools and parts come with the kit, and what will I still need?

The kit arrives with the starter motor, starter relay solenoid, two motor screws, a pair of spark plugs, a set of wrenches and four zip ties. That covers most small repairs and the mounting hardware for a direct replacement. You may still need basic hand tools, a socket set and a service manual for torque specs depending on your vehicle.

• Included: starter motor, relay solenoid, 2 mounting screws, spark plugs, wrenches, 4 zip ties.
• Recommended additional tools: socket set, torque wrench, service manual for your model.
• No drilling required for standard GY6 mounts—designed for direct fit.

How durable is this replacement and what materials are used?

The design emphasizes longevity under typical riding and starting cycles, and the manufacturing tolerances match common OEM configurations. While robust, longevity also depends on proper installation and vehicle maintenance.
