Engine Magneto Flywheel Woodruff Key – Hyosung GT125R GV125 GT125

Description

When you are deep into a complex 125cc power plant restoration, tiny internal components frequently create the most notable assembly headaches. A worn, squashed, or slightly twisted woodruff crescent piece lets the heavy alternator hub creep out of position on its tapered seat. This movement introduces erratic ignition timing errors that can be an absolute nightmare to locate properly during workshop troubleshooting. This high-tensile steel slot tab functions as the definitive hardware replacement for your bike, making sure that your electrical generator hub remains anchored stably across extensive mileage on everyday roads.   This will also fit the 250cc model, just select from the drop down!

🔧 Install Tips

• The Lubricant Retention Trick: Spread a tiny dab of thick mechanical grease direct inside the shaft slot before seating the key piece. This minor adhesion keeps the hardware stable and stops it from shifting or falling as you guide the heavy magneto over the nose.
• Avoid Forced Seating: The flywheel inner channel should slide squarely across the tab without requiring brute force. If you experience heavy resistance, back the rotor off gently to check if the crescent piece has tilted back inside its channel.
• Manufacturer Reference Cross-Match: Directly replaces internal factory hardware record number 08341-31039.
