The Boost Bottle, also known as a power jet, is a tuning part that can be installed at a scooter's carburetor. Its main purpose is to increase the amount of fuel that is supplied to the engine, which in turn can increase power and torque. The Boost Bottle works by increasing the fuel pressure in the carburetor. It is a small plastic container that attaches to the carburetor, usually between the carburetor and the air filter. The Boost Bottle is filled with fuel, and when the engine is running and the carburetor sucks in fuel, the Boost Bottle increases the fuel pressure, causing more fuel to be delivered to the engine. This can result in a noticeable increase in power and performance.
It's worth noting that while the Boost Bottle can be a relatively inexpensive and easy way to increase horsepower, it can also affect a scooter's fuel efficiency and emissions, so it's important to make sure your scooter still complies with local regulations. Additionally, the Boost Bottle is not suitable for all scooters, and it is important to check that it is compatible with your scooter's carburetor and that it is recommended by the manufacturer. It is also important to properly install and adjust the Boost Bottle to avoid any damage to the engine or carburetor.
