Pay attention to your health

Be sure to cool the hot car before washing, and suddenly wash the engine, exhaust pipe and other parts with cold water. The principle of thermal expansion and cold contraction is well known. Thermal expansion and cold contraction will destroy the oil seals of all parts, leading to engine oil leakage. Many motorcycle engines leak oil slightly. That's the reason. 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.

Headlights, left and right handrails, switches, exhaust ports (preferably blocked with things), speakers, cremation plugs, air filters, batteries and other components are best not to be washed directly with water;

There are circuits in these parts, which will lead to short circuit or leakage after being damp, and there will be faults such as no light, no horn, no fire and weak drive. It's best to scrub with a rag.
