This stator assembly is built to help the ignition system maintain clean spark delivery by supplying consistent electrical output as the flywheel rotates. The design priorities are especially important on Yamaha applications where ignition stability depends on clean stator output.

Design & Materials

• The coil assembly is built to resist breakdown from heat, oil mist, humidity, and repeated thermal expansion.
• Heavy-duty winding insulation helps prevent shorting between coil layers during extended operation.
• Precision-wound copper coils are used to promote efficient voltage generation and stable output.
• Epoxy encapsulation helps shield internal windings from moisture, vibration, and corrosion.

Ignition System Benefits

• Engineered to meet OEM-style electrical output characteristics.
• Helps correct intermittent spark loss caused by heat-sensitive stator windings.
• Supports dependable starting by delivering the voltage needed by the ignition module.
• Helps the ignition system recover from weak output, hard starting, and cylinder drop-out symptoms.

Common Symptoms of Stator Failure

• Unstable ignition output
• Poor acceleration caused by weak ignition energy
• Hard starting
• No-start conditions
• Random cylinder drop-out

Clean grounds, sound connectors, and correct flywheel condition are important for reliable stator performance after replacement.
