What's wrong with the motorcycle feeling that it can't give oil?
1. Dilution of mixed gas leads to insufficient thrust of gas acting on piston, prolonged combustion time and overheating of engine after ignition and explosion. The reason for judging poor engine oil is poor acceleration during operation. When the throttle or oil pump is pulled by hand, the acceleration will be improved, but when the rich mixture is not used, the acceleration will be weak. At this time, we can say that the motorcycle is in a state of poor oil.
There are many reasons for poor oil, including: the oil needle is too low; Oil level adjustment is too low; The main metering hole is partially blocked; The carburetor interface is loose and leaking; The air filter is not installed; The fuel switch of the fuel tank has poor oil supply.
2. The crankcase of the two-stroke engine is poorly sealed: the crankshaft oil seal at the generator side fails and leaks oil; The joint surface of crankcase seam leaks air; The joint surface of crankcase and cylinder leaks air or the piston is assembled in the wrong direction.
3. Reed valve of two-stroke engine Reason: The reed valve is damaged; The rotary valve was installed backwards, causing the carburetor to spray backwards.
Extended data:
Attention should be paid to riding a motorcycle:
1, don't go to the car wash shop or ask others to help you wash your car unless you have to. Car wash shops seem to have complete tools and standardized operation, but there are also cases of pursuing efficiency and poor results. If it is not good, it will also cause cremation plugs and various lines to break down.
2. Be sure to let the hot car cool before washing the car. Suddenly washing the engine, exhaust pipe and other parts with cold water, the principle of thermal expansion and cold contraction is very clear to everyone, which will destroy the oil seals of various parts and lead to oil leakage of the engine. Many motorcycle engines leak oil slightly. 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.
3. Headlights, left and right handrails, switches, exhaust holes (preferably plugged with something), speakers, cremation plugs, air filters, batteries and other components are best not to be washed directly with water. These parts have circuits, which will lead to short circuit or leakage, and there will be failures such as no light, no horn, no fire and driving fatigue. You'd better scrub them with a rag.
4. When washing the car, you must clean the lower part of the engine and the radiator. It is recommended to dip it in a toothbrush for cleaning. The advantage of this is that it is beautiful and easy to find problems such as oil leakage.
5. After washing the car, dry the whole car with a dry rag, especially the switch, instrument, left and right handrails, cremation plug, fuel tank cover and other parts. Pay special attention to take off the cremation plug cap and shake it a few times, otherwise it will affect the ignition.
6. After drying, start the vehicle, idle sideways for 5- 10 minutes, drain the water in the exhaust pipe, then drive on the road at a medium speed for a few minutes or dry in the shade, and don't explode in the sun.
7. Every time it rains, after riding home and putting the car in storage, pay attention to dry the car, especially the exhaust pipe. Now the pollution is serious and the rain is acidic. Most of the exhaust pipes have long been rotten. Although it is troublesome, it is definitely the way to love a car.
8. After cleaning the car, you can spray wax on the shell, rub it evenly with a fine emery cloth, and re-lubricate the chain.
