1. Add lubricating oil in time. If the lubricating oil is not added in time, the engine oil level is too low, which will cause the engine oil temperature to be too high and cause poor lubrication. At this time, when the motorcycle is going up and downhill or driving on the winding mountain road, the oil filter screen will be exposed, and the oil pump will suck in air and interrupt the oil supply, causing serious accidents such as cylinder pulling and shaft burning.
Therefore, when the motorcycle engine oil is under the engraved line, add lubricating oil in time. 2. Do not add too much lubricating oil. If you add too much, the lubricating oil will easily flow into the combustion chamber when the engine is running, and even spray oil from the exhaust pipe, causing the unburned oil to produce a large amount of carbon deposits and gums on the top of the piston, valve seat and valve oil seal. Intensify the wear of mechanical parts, and even cause premature damage to piston rings, pistons and camshafts. Therefore, the lubricating oil should be strictly controlled between the upper and lower engraved lines of the oil scale.
3. Do not mix new and old lubricants. There are a lot of metal chips, colloids and oxides in the old engine oil. Mixing with the new engine oil will reduce the use effect and use time of the new engine oil, and will easily cause the oil passage to be blocked and the parts to wear. Therefore, do not mix new and old engine oils. 4
. Clean the classic motorcycle suppliers before adding lubricating oil. Due to the long-term operation of the machine, metal scraps will be deposited in the engine, blocking the oil filter, oil pump, and oil passages. Therefore, the engine should be warmed up for 5 minutes before adding new oil, then add 1 liter of diesel or kerosene, and run the engine at idle speed for 3 minutes, release the diesel, and add a little new lubricating oil to wash out the engine. Diesel oil, and then add new lubricating oil. In this way, metal shavings and glue can be washed away, and the smooth flow of the oil passage can be ensured.
