Since the metal part of the entire frame of the motorcycle can be called the negative pole, that is, the grounding iron, if some of the wires are accidentally contacted with the metal part, a short circuit will occur. The car with good condition is usually burned, but some cars may even be connected. The fuses are gone, they are all connected directly by the line. The large current generated during the short circuit will burn the rubber and cause spontaneous combustion.
The part that causes oil leakage is generally the oil path from the fuel tank to the carburetor. The rubber of the joint is aging, and the seal of the carburetor interface is damaged and aging, which will lead to external oil leakage. The hot summer will further promote the leakage of gasoline. Volatilization, combined with the previous several predisposing factors, can easily lead to spontaneous combustion.
How to prevent spontaneous combustion of motorcycle?
1.Always check whether the connecting posts and the connectors are loose and rusted;
2.Check whether the insulation around the flammable parts has insulation and cracking;
3.Check whether the wire connection has a virtual weld off;
4.Check the appearance of the oil circuit for leaks and heavy gasoline smell;
5.Do not abuse the accelerating pump when parking, to prevent excessive gasoline injection into the carburetor throat to increase leakage;
6.Prevent the motorcycle from being placed in a closed and non-ventilated space for a long time;
7.Clean the motorcycle in time
