Reasons Why a Motorcycle Cannot Start Without Compression

[KingLee]

Lack of compression is usually due to valves not sealing properly. Below is an introduction to throttle-related content: Function: The throttle controls the air entering the engine. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to generate power. Principle: The principle of the throttle is that in traditional engines, the throttle control mechanism operates via a cable (flexible steel wire) or linkage rod, connecting the accelerator pedal at one end and the throttle linkage plate at the other. Electronic throttles primarily use a throttle position sensor to control the throttle opening angle based on the engine's required energy, thereby regulating the amount of air intake.
