What modifications can increase the power and speed of a scooter?

Here is the information on scooter modifications: Increase air intake: Installing a mushroom head can significantly increase the air intake, but after modification, the scooter might struggle to accelerate, etc. This is because the increased air intake leads to a leaner air-fuel mixture. Appropriate adjustments should be made to the carburetor based on the scooter's condition. You can fine-tune the mixture screw to adjust the low-speed air-fuel ratio and then adjust the needle to adjust the high-speed air-fuel ratio, ensuring the mixture concentration is normal. Observe the spark plug's combustion color for comparison during adjustment. Modify the sprocket: A simple method is to replace the engine's small sprocket with a slightly larger one. Generally, increasing by two teeth is sufficient. This will reduce low-speed vibrations and allow the engine power to perform normally, increasing the top speed, although climbing ability may decrease slightly. If changing the small sprocket does not noticeably reduce vibrations, you can try replacing the rear sprocket. Generally, replacing the rear sprocket with one six teeth smaller than the original will yield significantly better results.

I've been modifying scooters for over a decade, and improving power and speed mainly relies on several key points. The core is upgrading engine components, such as installing a high-performance cylinder sleeve to increase displacement, or directly transplanting a larger engine unit. The intake and exhaust systems also can't be ignored—installing a high-flow air filter improves intake efficiency, and modifying the exhaust pipe enhances exhaust flow. I've tried racing exhaust pipes, which sound more aggressive and provide stronger acceleration. For the transmission, replacing with an efficient variator to adjust weight or gear ratio, and upgrading the clutch to reduce slippage for quicker starts. The cooling system can be enhanced with additional cooling fans or improved heat dissipation fins to prevent engine damage from overheating. Don't forget the tires—switching to high-grip track-level tires can better translate power into motion. However, after modifications, it's best to flash the ECU to optimize fuel supply; otherwise, the air-fuel mixture might become unbalanced. Increased power also means higher risks, so I must remind everyone that safety comes first—don't speed or violate traffic rules. My modified scooter undergoes regular brake system checks to ensure stability.
