What Causes High Temperature in Water-Cooled Motorcycles?

[SanLuna]

Here are the reasons for high temperature in water-cooled motorcycles: 1. Insufficient or leaking coolant: Lack of coolant or leaks can cause the motorcycle to overheat. 2. Blocked circulation system: If the small circulation is not smooth, when the engine starts, the temperature of the coolant in the cylinder block and head water jacket keeps rising but cannot circulate, and the water temperature at the thermostat cannot rise, preventing the thermostat from opening. When the water temperature in the jacket rises above the boiling point, with the intensification of molecular movement, the water temperature at the thermostat gradually rises, the thermostat opens, and the high-temperature, high-pressure water flow in the jacket rushes out of the filler cap, causing a temperature rise. 3. Small valve clearance: A small valve clearance can cause the valve to not close tightly, potentially prolonging the post-combustion period of the air-fuel mixture. Most of the heat generated during the post-combustion period is used for temperature rise rather than work, leading to engine overheating.
