1. Upgrade the engine. This can be done by installing a larger cylinder, piston, and carburetor, among other things.
2. Install performance enhancing accessories, including an aftermarket exhaust system, modified air intake, or high-performance spark plug.
3. Reduce weight by removing unnecessary components, such as a spare tire or passenger seat.
4. Make aerodynamic modifications, such as adding a front fairing or reducing drag by streamlining the bodywork.
5. Improve the tire performance by installing performance-oriented tires that provide better grip and traction.
6. Lighten the flywheel. This can be done by removing some material from the flywheel, but be careful not to remove too much or the engine will not be able to start.
7. Advance the ignition timing. This can be done by rotating the distributor a few degrees counterclockwise. This will cause the spark plug to fire earlier, which can give the engine a bit more power.
Keep in mind that modifying a scooter to go faster can be dangerous and may compromise its safety. It's important to consider all potential consequences and weigh the risks versus benefits before making any modifications. Additionally, these tips may not apply to all scooters, so it's best to consult an experienced mechanic or specialist before implementing them.
