New RMSTATOR Heavy-Duty Flywheel Rotor for Kawasaki Motorcycles.
Anyone who rides or repairs Kawasaki motorcycles is probably familiar with the flywheel problems common to these models. Most of these machines will experience at least one flywheel failure during their lifetime. Low-quality epoxy is used on OEM flywheels to secure the magnets to the rotor body. Over time and through repeated heat cycles, the epoxy can fail, allowing the magnets to come loose and contact the stator, potentially causing catastrophic damage.
For years, service shops and dealerships have offered low-cost repairs for Kawasaki flywheels as an alternative to the $400+ OEM replacement. While this may seem like a good idea initially, there are some serious issues.
A common repair involves using JB Weld Marine Blue Epoxy to reattach loose original magnets or install new ones. These repairs may work in the short term when done correctly. However, they can cause immediate problems and affect the long-term reliability of the motorcycle.
A Heavy-Duty Flywheel to the Rescue!
The new RMSTATOR heavy-duty flywheel rotor for Kawasaki motorcycles is a well-priced solution to common OEM flywheel problems and an excellent alternative to the mechanical issues that can arise from repairs.
Features:
-
Built to OEM size: Fits precisely for straightforward installation.
-
Improved epoxy: Uses high-temperature epoxy that is stronger than OEM, helping prevent magnet detachment.
-
High-grade steel capping: Prevents harsh additives in motor oil from degrading the epoxy securing the magnets. If a magnet does come loose, it remains contained within the sleeve, preventing contact with the stator.
-
Precise balancing: Helps eliminate crankshaft vibrations for longer engine life.
-
Shop with confidence: Two-year warranty. All products are tested.
Why Cheap Repairs Won't Work
Stronger epoxy repairs may fix flywheel problems in the short term, but they can affect the long-term performance and reliability of the motorcycle.
-
Remaining OEM magnets: Original magnets can still come loose at any time.
-
Magnet alignment: Correct magnet alignment around the flywheel is critical for proper stator operation. Even minor misalignment can significantly reduce stator efficiency.
-
Magnet spacing: Excessive epoxy or incorrect magnet spacing can affect flywheel balance, potentially causing stator contact or crankshaft damage.
-
Incorrect replacement magnets: The magnetic field strength of replacement magnets must match the originals. Stronger magnets can quickly cause stator failure, while weaker magnets can significantly reduce stator output.
-
Wrong epoxy properties: Epoxy not rated to withstand high temperatures and oil immersion permanently can quickly cause serious failure.
-
Oil contamination: Incorrect epoxy can contaminate the crankcase oil and damage the motor.
For these reasons, we strongly recommend replacing a broken flywheel with a new 400+ OEM unit or this new heavy-duty flywheel.
Before attempting to start the Kawasaki, adjust the air gap. Rotate the flywheel until the raised node is aligned with the pick-up/pulser coil, then adjust the gap as close as possible, but no less than 0.010".
Warning:
Risk of electric shock. Disconnect the battery before servicing.
Ensure proper installation by a qualified technician to avoid malfunction.
