Precautions for motorcycles
1, be sure to cool the hot car before washing it. Suddenly flushing the engine, exhaust pipe and other parts with cold water, the principle of thermal expansion and cold contraction is clear to everyone, which will destroy the oil seals of various parts and lead to oil leakage of the engine. Many motorcycle engines are slightly leaking oil. It will also cause the chromium plating layer at the joint between the exhaust pipe and the engine to fall off and oxidize and rust.
2. Headlights, left and right handrails, switches, exhaust vents (it is best to plug them with something), horns, cremation plugs, air filters, batteries and other parts are best not to be washed directly with water. These parts have circuits, which will lead to short circuit or leakage when wet, and there will be failures such as lights not working, horns not ringing, fires not happening, and driving fatigue. It is best to scrub them with a rag.
3. When washing the car, you must clean the lower part of the engine and the radiator. It is recommended to use a toothbrush to dip in the cleaning. This has the advantage of being beautiful and easy to find problems such as engine oil leakage.
4. After washing the car, dry the whole car with a dry rag, especially the switch, instrument, left and right handrails, cremation plug, fuel tank cover and other parts. Pay special attention to take off the cremation plug cap and throw it out a few times, otherwise it will affect the ignition.
