It is very harmful to the starter. The maximum duration of each electric start must not exceed 5 seconds. If it doesn't work, wait a while and then restart it. If the car is cold, you can ride in it. with both feet. The goal is to remove the original residue in the cylinder and inhale the new oil and gas mixture. This way of starting is very beneficial for the car.

2 Change the spark plug
3 Change the cylinder line The total cost of one spark plug is less than 30 yuan
What is the reason for which the exhaust pipe of a large-displacement motorcycle may catch fire
Check whether the spark plug and carburetor are normal.
There are many reasons why Wuyang Honda scooter cannot ignite. You can check whether the spark plug and high voltage wire have enough electricityhigh voltage tee, if the gas distribution timing is correct and if the carburetor is clogged. Or improper debugging, if the negative pressure tank switch is damaged, causing the cylinder to flood, if the exhaust pipe is blocked and blocked, if there is air leakage in the exhaust pipe intake or other pipes related to the engine and carburetor, whether the valve clearance is too small or poorly closed, etc. , this will cause the fire to fail.
Possible reasons are:
1. The mixture is too rich (for example, the air filter is clogged or the carburetor mixture ratio is incorrectly adjusted).

2. Engine oilTo maintain large displacement motorcycles, you must choose the right engine oil. For multi-cylinder, high-speed crankshafts, use semi-synthetic or higher engine oil. . If possible, use full synthetic motor oil. Wind Oil Cold cars have higher engine oil requirements than wind cooled carswater. ?
3. Gasoline
The compression ratio of large-displacement motorcycles is generally relatively high, so it is recommended to use premium gasoline.
4. Air filter
It is necessary to use a clean air filter, because the air filter is to the motorcycle what the lungs are to people. Once the air filter is damaged, dust, sand and soil It will enter the cylinder, wear the rings and valves, and over time the valves will have carbon deposits, which will significantly reduce the durability and power of the car, so you need to choose a good air filter.
