This replacement stator is designed to support stable ignition output by converting flywheel rotation into controlled electrical energy for the ignition circuit. The design priorities are especially important on Yamaha applications where ignition stability depends on clean stator output.

Construction Details

• Laminated core sections help concentrate magnetic flux from the flywheel magnets for reliable electrical production.
• The coil assembly is built to resist breakdown from heat, oil mist, humidity, and repeated thermal expansion.
• The stator body is designed to maintain proper coil alignment under continuous flywheel rotation.
• Sealed construction helps reduce moisture intrusion that can lead to weak spark or no-spark conditions.

Operating Features

• Helps the ignition system recover from weak output, hard starting, and cylinder drop-out symptoms.
• Designed to maintain stable voltage as engine load and RPM change.
• Supports smooth acceleration by helping the ignition system maintain consistent energy.
• Supports dependable starting by delivering the voltage needed by the ignition module.

Failure Symptoms to Check

• Spark loss after warm-up
• No-start conditions
• Random cylinder drop-out
• Poor acceleration caused by weak ignition energy
• Hard starting

Always compare resistance and peak-voltage readings to the correct service specifications when diagnosing a suspected stator failure.
