Battery condition is extremely important. No stator can work correctly with a bad or weak battery. Always fully charge your battery before performing any charging system tests or replacing parts. If there is any doubt, have the battery load tested or replaced.

New Heavy Duty Flywheel Rotor + Ring Gear + Stator + Gasket for
Yamaha ATV
Introducing our newest Heavy Duty Flywheel Rotor For Yamaha ATV
Anyone who rides or repairs the Yamaha ATV is probably familiar with the flywheel problems common to these models. Most of these vehicles will have at least one flywheel failure in their lifetime so far. Low quality epoxy was used on OEM flywheels to secure the magnets to the rotor body. Over time and many heat cycles, the epoxy fails allowing the magnets to come loose and contact the stator, potentially causing catastrophic damage.
For years, service shops & dealerships have offered low cost repairs for Yamaha flywheels to save the 400$+ OEM replacement. This sounds like a great idea at first, but there are some serious issues!
The common repair is using JB Weld© Marine Blue Epoxy to reattach the loose original magnets, or to install new ones. Epoxy fixes do repair flywheels in short term, if they are done correctly. However, this kind of repair can easily cause immediate problems, and impact long term reliability of your ATV
Watch Evan, our head of engineering, explaining why you must not repair a flywheel.
A Heavy Duty Flywheel to the rescue!
New RMSTATOR heavy-duty flywheel rotor for Yamaha ATV is a well-priced solution to problems with the OEM flywheel, and an excellent alternative to all the mechanical troubles you can encounter with a repair.
Features
-
Built to OEM size
Fits precisely in your ride: install it and forget it. -
Improved epoxy
Uses high temperature epoxy that is stronger than OEM, eliminating the possibility of magnet detachment. -
High grade steel capping

Prevents harsh additives in motor oil from degrading the epoxy attaching the magnets. Though extremely unlikely, if a magnet did ever come loose, it would remain in the sleeve preventing contact with the stator. -
Precise balancing
Eliminates crankshaft vibrations for longer engine longevity. -
Shop with confidence
One year warranty. All products are tested.
Don't waste time with temporary solutions, and start fixing your ride like a pro!

Why cheap repairs won't work?
Quick stronger epoxy fixes do repair flywheels in short term. It might however impair long term performance and reliability of your ride.
Remaining OEM magnets:
Original magnets remaining can still come loose at any time.
Magnet alignment:
The alignment of magnets around the flywheel is critical for proper stator operation. Even very fine misalignment will reduce stator efficiency significantly.
Magnet spacing:
Excessive epoxy or incorrect magnet spacing around the flywheel can easily affect the flywheel balance. This can cause stator contact or even crankshaft damages.
Incorrect replacement magnets:
The magnetic field strength of new magnets MUST match the originals. Stator failure can occur quickly with stronger magnets and stator output can be decreased significantly using weaker magnets.
Wrong epoxy properties:
Epoxy that is not rated to permanently handle high temperatures and oil immersion can quickly cause a serious failure.
Oil contamination:
Wrong epoxy for the application can also contaminate the crankcase oil, damaging the motor.
All these reasons make us strongly recommend that you replace your broken flywheel with a new 400+ OEM one or our new heavy duty flywheel.

Installation
Installation
- Check the AC output of the stator.
- Replace any burned or corroded connectors on stator and regulator/rectifier
- Check and repair any melted wiring.
- Use hi-temp dielectric grease on all connectors
Our stator may use a different wire color code than your original.
All of the wires are installed in the correct order; please do not change any of the wiring configurations.
This stator is designed as a direct plug-in replacement and should be used as such.
When bolting stator in, always use locking compound.
If our stator includes a pickup coil, always make sure the air gap is correct upon installation; we suggest as close as possible no less than 0.010".
Warning:
Before attempting to start your Yamaha, adjusting the air gap is necessary. Rotate the flywheel so the raised node is lined up with the pick up/pulser coil and adjust as close as possible but no less than 0.010".
Ensure proper installation by a qualified technician to avoid malfunction.Risk of electric shock. Disconnect the battery before servicing.
Ensure proper installation by a qualified technician to avoid malfunction.
