Motorcycle carburetor: When does it need to be cleaned? How to clean?

Motorcycle carburettor is one of the key components of the engine's fuel supply system. It mixes petrol with air in a specific ratio and then transports it to the engine's combustion chamber for combustion.
A motorcycle carburettor mainly uses the Venturi effect:
when air passes through a narrow duct, the flow velocity increases and the pressure decreases, causing petrol to be sucked into the nozzle and mixed with air to form a combustible gas.
✅ Precise mixing ratio: Ensures that air and fuel are mixed evenly to improve combustion efficiency.
✅ Excellent cold start performance: Equipped with manual/automatic choke to adapt to low-temperature environments.
✅ Sensitive response: Instant throttle response for an improved driving experience.
✅ Compact design for easy installation: Compatible with various vehicle models, facilitating replacement and calibration.
✅ Energy-efficient and durable: Constructed from high-quality materials for long-lasting performance and reduced maintenance costs.
