Why can't the Geely Emgrand GS accelerate?

[TylerRose]

Reasons for the Geely Emgrand GS not being able to accelerate: fuel supply system failure, decrease in engine compression ratio. Fuel supply system failure: Excessive fuel leads to an overly rich air-fuel mixture, causing the motorcycle to lack power at low speeds. An overly rich mixture lacks sufficient oxygen during combustion, resulting in incomplete combustion, reduced power output, poorer fuel efficiency, and the tendency to produce excessive carbon deposits that clog the exhaust system, exacerbating the power loss. Decrease in engine compression ratio: The engine's power is directly linked to its compression ratio. With vehicle usage, internal engine components wear out. If key components experience excessive wear, the engine's compression ratio will decrease.
