On a two-stroke engine, as the piston moves down during the intake stroke, it creates a vacuum that draws the air-fuel mixture from the carburettor into the crankcase. However, when the piston starts moving up during the compression stroke, some of the mixture might be forced back into the carburettor due to inertia and pressure imbalances. This is known as reversion, and it can negatively affect engine performance.
The boost bottle works by temporarily storing the air-fuel mixture during the downward piston movement and releasing it back into the crankcase as the piston starts to move up. This helps maintain the momentum of the mixture and prevents it from being forced back into the carburettor. By increasing the mixture velocity and reducing reversion, the boost bottle improves the overall efficiency of the engine.
A boost bottle can provide several benefits for a Yamaha Blaster, including:
1. Increased power and torque, particularly at low-end and mid-range RPMs.
2. Improved throttle response and acceleration.
3. Smoother power delivery and reduced vibration.
4. Increased fuel efficiency.
Installing a boost bottle on a Yamaha Blaster is relatively straightforward, but it's recommended to follow the instructions provided by the manufacturer of the specific boost bottle being used. Generally, it involves connecting the boost bottle to the crankcase and ensuring any vacuum lines are properly attached.
It's worth noting that while boost bottles can offer performance benefits, they might not be suitable for all riding styles and conditions. Some riders prefer the feel of a bike without a boost bottle, so personal preferences and testing are important factors to consider before making a decision.
