This article will introduce in detail the causes and solutions of the abnormal noise of the motorcycle engine from the following aspects. I. The reason for the abnormal sound of the motorcycle engine 1. The sound of piston knocking When the gap between the piston and the cylinder block increases, there will be a sound of the piston knocking on the cylinder block. This kind of clapping is generally more obvious, especially when starting the vehicle.The reason for this sound is likely to be the aging or damage of certain parts, such as connecting rod bearings, piston rings and valve sheets. Two. Cracks appear on the crankshaft connecting rod. If the engine is found buzzing, it is very likely that the crankshaft connecting rod has cracks. At this time, it is necessary to check whether there are cracks in the crankshaft connecting rod. If it is confirmed that it has been damaged, it needs to be repaired or replaced. 3. Valve click When the valve click occurs in the engine, it means that some parts inside the engine are worn out, such as the wear of the crankshaft tile of the motorcycle, or the unbalanced operation of the crankshaft. At this time, the damaged parts need to be replaced. Four. The problem of the camshaft assumes that there is a hissing sound in the engine, it may be related to the camshaft. The camshaft is an important part of the motorcycle engine. If it fails, it will cause a hissing sound. At this time, it is necessary to check whether the camshaft is damaged or worn, and it needs to be repaired or replaced.5. Friction noise When there is friction noise in the engine, it may be caused by friction between engine parts. This kind of sound is usually rattling and needs to be overhauled in time to prevent the problem from expanding. II. The solution to the abnormal sound of motorcycle engine 1. Replace parts. According to the problems found in the inspection, the damaged parts need to be replaced in time. For example, if the inspection finds that there is a problem with the piston ring, a new piston ring needs to be replaced. Two. Cleaning and maintenance of the engine Regular cleaning and maintenance of the motorcycle engine can reduce jams and friction, reduce wear, and extend the life of the engine. 3. Add lubricating oil to the motorcycle engine. Adding lubricating oil can reduce friction, improve engine efficiency and extend engine life. Riders need to change the lubricating oil regularly and check the oil line to ensure unimpeded operation.Four. Check whether there is any foreign matter inside the engine. If there is any foreign matter inside the engine, it will cause abnormal engine noise. It is necessary to check and clean the engine regularly and ensure that the inside of the engine is clean and clean without foreign matter. 5. Regular inspection and maintenance of motorcycles requires frequent inspection and maintenance, especially the engine and transmission system. Regular maintenance of motorcycles can find and solve problems in time to ensure driving safety. In a word, engine noise is one of the common problems of motorcycles. Common causes include the wear and aging of pistons, valves, bearings and other parts. In order to alleviate these problems, riders need to regularly inspect and maintain motorcycles, replace or repair damaged parts in time, and strengthen the use of lubricating oil and keep the engine clean. As long as they follow these suggestions, riders can keep their motorcycles in good condition and enjoy a pleasant and safe journey.
