What Causes Oil Leakage When Starting a Motorcycle?

[Katie]

Minor oil leakage is caused by damage to the engine gasket. Function of Engine Oil: Engine oil is referred to as the lifeblood of the engine. In the engine, oil not only serves as a lubricant but also performs functions such as cleaning, sealing, buffering, rust prevention, and heat dissipation. Carburetor Fuel Intake System: The carburetor fuel intake system is a dynamic equilibrium system. The float inside the float chamber, under the buoyancy of gasoline, drives the needle valve to continuously adjust the gap between the needle valve and the valve seat, thereby controlling the fuel intake and maintaining dynamic stability of the fuel level in the float chamber under various operating conditions of the motorcycle.
