electronic speedometer for motorcycle not work properly
The main function of the riding instrument is to display the driving data. If the instrument is damaged, it will cause some trouble in normal use. What causes the failure of the motorcycle speedometer?
To understand this problem, we should first understand the main components of the speedometer. There are two types of motorcycle instruments: mechanical and electronic. The mechanical speedometer has a relatively simple structure, mainly consisting of instruments, mileage lines, and speed teeth. If the speedometer of this machine fails, it is generally caused by the damage of the mileage line and the speed gear. During inspection, you can remove the mileage line and observe the rotation of the counting gear. If it can rotate normally, it indicates that the mileage line is damaged. If it cannot rotate normally, the fault can be eliminated after replacing the speed gear. The electronic instruments are mainly composed of speed sensors and digital instruments. The failure probability of this system is generally very small. However, if the failure occurs, the maintenance cost is relatively high. This is mainly because the instruments and speed sensors are integrated, so the replacement cost will be more expensive. However, the failure of this system should be mainly due to the problem of the instruments, because the failure probability of the sensors is not large, Therefore, the key point should be to check the instrument. The above are the main reasons for the failure of the motorcycle speedometer. Users of mechanical instruments can repair them by themselves, while electronic instruments can only be repaired by professionals. Because users do not have the skills in this field, they must not dismantle them randomly to avoid unnecessary losses.
Reasons and solutions for the idling speedometer runout: 1. The idling speedometer runout is generally caused by carbon deposits inside the throttle valve and the idling motor. Cleaning the throttle valve and the idling motor can solve the problem; 2. Poor gasoline quality will lead to poor atomization effect of the nozzle and insufficient combustion of the mixture in the cylinder, which will also cause the speedometer to jump. It is recommended to use high-grade gasoline to clean the fuel system after using this tank of gasoline; 3. If the spark plug is misfiring, one or more cylinders will not work, and the speedometer will also jump. Check whether the ceramic part of the spark plug has cracks, and whether the ignition module is normal.
The pointer of the speedometer of the motorcycle is either high or low. The possible causes are mainly the damage of the speedometer, the abrasion and slipping of the speedometer line or the speed gear in the front wheel. The failure of the pointer of the speedometer does not move is in the rotation or transmission part of the speedometer. First check the transmission part, remove the power output end of the odometer flexible shaft installed on the front wheel drum, pull out the flexible shaft core, and check whether the birch on the head is worn. If the birch is worn into a round shape, it should be replaced. If there is no wear, remove the hose end connecting the thread of the odometer, insert the square birch head of the hose directly into the square hole of the odometer without installing the flexible sleeve, and rotate the flexible shaft with your finger. If the pointer of the speedometer still does not move, it indicates that the fault is in the rotating part of the odometer.
