What are the reasons for insufficient fuel supply after a motorcycle ignition?

[Serenity]

The reasons for insufficient fuel supply after a motorcycle ignition are as follows: 1. The fuel tank negative pressure switch is blocked or the negative pressure suction pipe is leaking, causing the fuel pipe to fail to deliver fuel normally. 2. The carburetor is clogged or there is water at the bottom of the carburetor float chamber. Additional information: Precautions: 1. Avoid taking your motorcycle to a car wash or letting others wash it unless absolutely necessary. Car washes may seem well-equipped and operate with standard procedures, but their pursuit of efficiency often leads to poor results. It may also cause damage to the spark plug and various circuits. 2. Always let the hot engine cool down before washing. Suddenly rinsing the engine, exhaust pipe, and other components with cold water can cause damage due to thermal expansion and contraction, leading to oil seal failure and engine oil leakage. 3. Avoid direct water contact with the headlight, left and right handrails, ignition switch, exhaust pipe outlet (preferably blocked with something), horn, spark plug, air filter, battery, and other parts. These areas contain electrical circuits, and getting them wet can cause short circuits or leakage.
