Product Overview
Unlock your engine’s electrical system with the GOOFIT Professional Flywheel Puller. If you are replacing a stator, adjusting timing, or rebuilding a GY6 engine, this precision-engineered tool is non-negotiable.
Unlike single-sided pullers, this Dual-Head (Bipolar) design features both 24mm and 27mm threads in one solid tool. It is the "Master Key" for almost all Chinese-made 50cc, 125cc, and 150cc scooters, ATVs, and Dirt Bikes. Forget about hammering or prying—this puller uses mechanical leverage to safely remove the flywheel without damaging your crankshaft or magneto.
Dual-Head Specifications
Two essential sizes in a single heavy-duty tool:
| Thread Side | Diameter | Typical Fitment |
| Small Side (RH) | 24mm (0.95") | GY6 50cc Scooters, Mopeds, ATVs |
| Large Side (LH) | 27mm (1.06") | GY6 125cc/150cc, 139QMB & Performance ATVs |
Key Features
- Heat-Treated Industrial Steel: Forged from high-strength alloys and subjected to a rigorous heat-treatment process. This ensures maximum hardness and toughness, preventing threads from stripping even when dealing with stubborn, factory-seized flywheels.
- Double-Sided Versatility: No need to clutter your toolbox with multiple pullers. One side fits most 50cc engines, while the other side covers 125cc and 150cc models. It’s the perfect all-in-one solution for DIYers and professional mechanics alike.
- Safe Removal Mechanism: Specifically designed to apply even pressure directly to the crankshaft center. This protects your expensive flywheel and stator from deformation, keeping your vehicle’s performance optimized.
- Cost-Effective Maintenance: Stop paying high labor fees at the repair shop. With this simple-to-operate tool, you can replace your own stator or magneto in minutes, significantly shortening your maintenance cycle.
- Precision Machined Threads: Features clean, burr-free threads that engage perfectly with the flywheel, ensuring a secure grip and a smooth removal process.

Fitment FAQ
Will this part fit my specific model and year?
This magneto stator is intended for GY6 50cc-150cc. Key physical/spec details from the product data include 24mm, 27mm, 50cc. Use the compatibility table and product photos together before ordering.
Do I need to match the OEM part number?
Yes. If your original part has a stamped OEM or manufacturer number, match that number first before ordering. For this magneto stator, also compare the OEM number, outer/inner diameter, core height or thickness, plug shape, wire count, mounting holes, pickup position, and rubber grommet style. This is especially important for GY6 GY6 models because similar model names can use different parts by year or trim.
What models or situations does this part not fit?
Do not order this magneto stator for machines outside the listed compatibility, or for units with different plug layouts, pickup-coil positions, wire counts, stator diameters, or charging/ignition configurations. Do not rely only on the model name or engine size.
What should I check before ordering?
Before ordering, compare your original part with the photos and check the OEM number, outer/inner diameter, core height or thickness, plug shape, wire count, mounting holes, pickup position, and rubber grommet style. Recheck listed specs such as 24mm, 27mm, 50cc. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
Works as described, really great time saver
Made the job super easy!
This is a very robust and well built puller. The dual thread size perfectly fit and easily removed both flywheels from the vintage Yamaha enduros I have used it on.
Worked great on my little 110c pitbike.
works very well
