1, after starting the car, the idle speed is fast and slow, causing engine shaking, if it is the carburetor of the motorcycle, it may be the spark plug fault or the carburetor is not adjusted. If it is an electric spray motorcycle, it may be the spark plug and throttle carbon deposit.

2. For straddling bikes, serious shaking will occur after riding in gear, with a high probability that the rear wheel buffer block is worn, and it may also be that the engine main drive shaft keyway and the small tooth disk are seriously worn.

3, for the pedal motorcycle with infinite speed change, if the shaking occurs when starting, slightly normal, if more serious, it may be the transmission mechanism is worn, and the transmission box needs to be maintained.

4, after the vehicle rides up, the speed is not fast, the engine works normally, but it is found that the vehicle has regular shaking, it is likely that the front wheel or the rear wheel is bubbling and deformed, it should be replaced in time, otherwise it will seriously affect driving safety.

5, if it is braking, the wheel part of the squeak squeak jitter sound, should be the brake disc deformation, the need to replace the brake disc. If the brake block is excessively worn, it will also make this kind of sound, so it is necessary to check the motorcycle brake system.

6, for straddle motorcycles, if the refueling door shakes, it may be improper operation, because the gear is too high and the speed is too low. If the gear motorcycle in the process of driving, the engine has been transmitted jitter, that is the gear is broken.

7, if it is a large displacement sports car, such as Honda CBR650R, QJ race 600RS, etc., at the speed of 130km/h or so, there will be high-frequency vibration, which is the resonance of the four-cylinder machine, a normal phenomenon, can not be ruled out, if this type of vehicle after changing the tires, in 120km/h above greater shaking, We have to consider the balance of the front and rear tires.

8, if your motorcycle in the process of driving, more than 40km/h will occur dragon head shake, it is because your motorcycle installed a heavier rear trunk, affecting the center of gravity of the vehicle, resulting in dragon head shake, remove the rear trunk will be eliminated.
