Why Does a Motorcycle Stall When Shifting Gears?

[LaAlice]

Motorcycle stalling when shifting gears can be attributed to the following reasons: 1. Winter: Typically caused by low external temperatures, which reduce the fluidity of engine oil, leading to incomplete clutch disengagement. Most common motorcycles use wet clutches, also known as oil-bath clutches, where multiple paper-based clutch plates are immersed in engine oil that serves as a coolant. When the external temperature is too low, the oil's fluidity decreases and becomes sluggish, causing incomplete separation of the clutch plates. This results in the engine stalling as soon as a gear is engaged. 2. Spring, Autumn, and Summer: The first consideration should be whether the clutch cable has insufficient free play.
