How Many Kilometers for a Motorcycle's Second Maintenance?

Generally, the second maintenance for a motorcycle is recommended at 8000-10000 kilometers. Tires: When purchasing, avoid buying tires with overly shallow treads or retreaded tires. It's also advisable not to purchase used tires. New tires are the best choice because tires are made of rubber, which ages over time, significantly reducing tire performance. Additionally, avoid applying oils to the tires as oils have an affinity for rubber, which can easily lead to tire cracking and deterioration, greatly affecting driving safety. Body Shell: Rainwater is generally acidic, and acidic rain can be highly corrosive to metals and plastics. If your motorcycle gets dirty from riding or is exposed to rain, remember to rinse the body with water to mitigate some of the damage from acid rain. Engine Oil: The first oil change after purchasing a new motorcycle is crucial. It is recommended to change the oil for the first time after 500 kilometers, the second time after 1000 kilometers, and subsequently every 2000-3000 kilometers (adjust appropriately based on driving conditions).

What Causes High Temperature in Motorcycle Engines?

Here are the reasons for motorcycle engine overheating: Neglecting the break-in period: For newly purchased motorcycles, due to rough surfaces of components, certain deviations in geometric shapes and assembly positions, smaller contact areas between friction pair components, higher pressure per unit contact area, rapid increase in wear, and significant heat generation from friction. During the break-in period, it is essential to limit speed and load, perform timely maintenance, and replace lubricating oil. Poor lubrication: When the oil pump is damaged, oil supply is insufficient, lubricating oil quality is poor, or the lubricating oil deteriorates or is lacking, the heat transfer and dissipation functions weaken, leading to worsened lubrication conditions, rupture of the oil film between friction pairs, accelerated wear, and resulting in engine overheating. Poor cooling conditions: For air-cooled two-wheel motorcycles, improper installation can obstruct the cooling airflow to the front of the engine, severely reducing cooling air volume and causing engine overheating.

Can a Motorcycle Still Be Used After Being Submerged in Water?

It is not recommended to use a motorcycle after it has been submerged in water. Engine Damage: If the engine has been flooded, forcibly starting the motorcycle can cause severe deformation of the connecting rod. Additionally, insurance companies often refuse claims in such cases. Transmission Failure: If the water level rises above the engine compartment, the transmission is highly likely to be flooded. Once water enters the transmission, the vehicle may experience issues such as slipping, shaking, and rough gear shifting. This can also affect the transmission's lifespan and may even render it unusable. Interior Mold: The interior components are mostly made of absorbent materials. Rainwater contains numerous impurities and bacteria, and the enclosed, poorly ventilated space inside the motorcycle leads to extremely high humidity after submersion. This environment is conducive to mold growth.
