motorcycle speedometer not working
If the speedometer of the motorcycle does not move, the dial may be damaged. The details are as follows: If the speed line turns with the front wheels:
It indicates that it is a problem with the dial. It may be that the deceleration teeth in the dial are broken or loose. This situation is more troublesome, because there is no separate speed dial for sale, and only the motorcycle assembly can be replaced.
If the speed line does not turn with the front wheels:
It means that the speed line may be broken or the counting claw in the front axle is too worn. It is necessary to further check the speed line to see if it can be pulled out from the front axle. If it can be pulled out, only the line needs to be replaced, otherwise the speedometer assembly needs to be replaced.
If neither the speedometer nor the odometer move:
Check whether the odometer line is off or broken, and whether the speed gear in the front wheel is damaged. If the mileage of the odometer can go, only the speed pointer does not go, and only the odometer needs to be replaced.
The motorcycle odometer and speedometer are not working, it is possible that the dial thread is lost. You can check the dial wire, the wire is usually near the front brake disc and leads there from the odometer. If you can't find it, take it to a repair shop. The car speedometer is divided into two types: roller counter and dot-distance LCD screen. It consists of a speedometer that indicates the speed of the car and an odometer that records the distance traveled by the car. The two are installed in a common housing and are composed of Driven by the same shaft. Ordinary speedometers are generally magnetic induction type. The roller counter is a purely mechanical instrument commonly used in the past. One end is connected to the output shaft of the gearbox through a flexible shaft, and the other end is connected to the odometer; and now the more commonly used electronic instrument, it is generally on the output shaft of the gearbox or the odometer. A speed sensor is installed on the wheel, and the read speed is converted into vehicle speed and history through the calculation formula embedded in the control module. Either way, in the final analysis, the data comes from the speed of the output of the transmission system (gearbox output shaft or wheel), knowing the speed of the wheel, such as how many revolutions per minute, and then calculating the circumference of the wheel (that is, the wheel the distance traveled in one turn) is counted, and the speed comes out, and the same is true for the mileage.
