Sometimes in the frenzy of a complete engine overhaul smaller parts like clutch springs are overlooked when it comes to refurbishment. To create friction in the clutch the springs included in the assembly press the surface friction area of ​​the friction plates onto the simple separation plates. These in turn are exposed to high mechanical energy. When the friction between the respective clutch discs adds up to more than the torque coming from the engine, the power can be further transferred to the gearbox. Over time clutch springs become weaker or may even break. For these reasons, and more, they must be regularly replaced. We also recommend stronger grade springs to be used (available in different grades) even for milder road tuning projects to allow all the extra power created to reach the rear wheel. The L clutch spring is required for engines with 18-22 hp on the rear wheel, the XL for more than 22 hp and the XXL for more than 25 hp. Conclusion: If you are upgrading or even just maintaining your scooter, don't forget to change the clutch springs!
