Flywheel + Stator for Polaris Sportsman 335 400 500 | Xplorer 500 | Magnum 425 | Worker 335 | Ranger Series 11 1995-2004
There are more than one possible stator that can match with this flywheel, please compare your part with our picture. The other stator is in the kit flywheel + stator RMS900-104042.
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.

Before attempting to start your Polaris vehicule 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".Before installing your new stator
- 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".

Introducing our newest Heavy Duty Flywheel Rotor For Polaris 400 & 500cc ATVs.
Anyone who rides or repairs the Polaris 400 & 500cc ATVs is probably familiar with the flywheel problems common to these models. Most of these bikes 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 Polaris 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.
A Heavy Duty Flywheel to the rescue!
New RMSTATOR heavy-duty flywheel rotor for Polaris ATVs 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.
Built to OEM size
Fits precisely in your ride: install it and forget it.
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.
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.
The alignment of magnets around the flywheel is critical for proper stator operation. Even very fine misalignment will reduce stator efficiency significantly.
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.
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.
