How to solve the vibration of motorcycle refueling door?

1, when gasoline burns, the gas in the cylinder expands rapidly, causing vibration; This may be related to the quality of gasoline, or the label of gasoline added may be incorrect.

2. Check whether the clutch is normal; The relationship between clutch pressure plate and friction plate is lip-tooth dependent. When there is a problem with the friction plate, it will accelerate the wear of the pressure plate and even the flywheel, which is mainly manifested in the difficulty of shifting gears, unclear separation and starting trembling.

3. It may be that the clearance between the cam, rocker arm and valve of the engine is too large, or some bearings or bearing seats are broken.

Extended data

Characteristics of motorcycle engine

(1) The engine is a two-stroke or four-stroke gasoline engine.

(2) Adopt air cooling, including natural air cooling and forced air cooling. The general model adopts natural air cooling, relying on the air blowing through the cylinder head and the radiator on the cylinder liner to take away the heat. In order to ensure the cooling of high-power motorcycle engine at low speed and before driving, forced air cooling is adopted, equipped with a fan and an air guide cover, and the heat sink is cooled by forced air.

(3) The engine speed is high, generally above 5000 rpm. The rising power (the effective power per liter of engine displacement) is relatively large, generally around 60kw/ liter. This shows that the motorcycle engine has a high degree of reinforcement and a small overall size.

(4) The engine crankcase, clutch and gearbox are designed as a whole with compact structure.
