When you release the clutch lever on a motorcycle while the engine is running, the engine's power is transmitted to the drivetrain, which includes the transmission, clutch, and ultimately the wheels. Releasing the clutch lever gradually engages the clutch plates, allowing power to transfer from the engine to the drivetrain and propel the motorcycle forward.
If you release the clutch lever too quickly without properly matching the engine's speed to the wheel speed, a sudden jolt may occur, causing the engine to stall. This happens because the abrupt engagement of the clutch overwhelms the engine's ability to maintain its rotational speed, resulting in a loss of power and the engine shutting off.
To prevent stalling, it is important to release the clutch lever gradually while simultaneously applying throttle to match the engine speed with the wheel speed. This technique is commonly known as "letting the clutch out smoothly" or "feathering the clutch." By smoothly releasing the clutch lever and applying throttle, you can provide the engine with enough power to maintain its speed and keep the motorcycle running smoothly.
