Description
The manufacturer quietly changed the internal flywheel dimensions on their late facelift 125cc carb models, which has left riders with a massive mechanical headache. Finding the original smaller factory components on the internet has become incredibly difficult and highly expensive. This exclusive HyoRiders generator conversion kit answers that exact maintenance problem while delivering a genuine real-world performance upgrade for your bike. We combine a robust, uprated heavy wheel along with a brand-new thicker stator coil block. This provides your V-twin motor with a far punchier engine idle, stable electrical current tracking at high speeds, and the long-distance reliability you need during your ongoing restoration project.
Many younger riders or commuter owners are naturally skeptical about electrical claims on these later carbs bikes, but our real-world donor testing confirms the engineering facts. A heavier spinning wheel weight adds vital kinetic momentum down low, meaning your engine shoots up to a clean 1,500 RPM on cold mornings without sputtering or dying out. The uprated coil windings run significantly cooler than standard setups, dramatically dropping internal heat stress to protect your ignition lines. This is a complete drop-in package that updates your bike’s old charging system completely, keeping your clock, lights, and spark strong on everyday journeys.

🔧 Installation Tips
Full step-by-step fitting instructions are available by email on request. This is a standard drop-in task that can usually be completed on your workbench in under an hour without modifications. Check out our product media gallery for active video proof of this kit running smoothly on our own machines!
- Flywheel Puller Tool Included: We pack the specialized heavy-duty removal tool right inside the box with your order. Other shops charge extra for this hardware, but we include it free to ensure your maintenance project runs easily.
- Drain and Swap Your Oil: You will need to drain your side engine oil completely before unbolting the left stator casing cover. Because you are dropping your fluids, this is the absolute best moment to complete a clean service swap. Grab a fresh engine oil filter set to complete your task: Oil Filter Service Kit.
- Wipe Casing Surfaces Flat: Use a clean cloth to thoroughly remove old paper gasket residue and oil grime from the engine casing lips before seating the fresh side gasket. Gaps will cause an immediate engine oil leak.

i would recommend getting it has given my bike a higher top speed and overall it is better than stock i have quite a few upgrades with this doh i have k&n air filter full black widow exhaust up jet performance coils and plugs and regulator bigger fuel lines and vac lines i would say this kit is worth the money also got to think about the time taken to develope the product finding out what fits what and what works on the bike

This custom kit is brilliant and well worth the money. My old stator was fried by faulty electrics which had to be replaced.
This stator is much better and the new flywheel gives a big boost in torque. Throttle is much smoother and responsive. Handles lower speeds in a higher gear perfectly where as the old stock one felt really flat. 30mph in 4rh gear no problem.
The bike just loves this.
Again decent service and quick delivery. All parts and tools needed are supplied along with excellent step by step instructions by Marcel. I never attempted anything like this before and with the step by step guidance fitted it perfectly.
If you’re ordering a new stator definitely consider this full kit.
