how to connect a needle tachometer

• 2023-05-26

When installing the electronic needle tachometer on a motorcycle, the green line is connected to the rack, the black line is connected to the positive output of the ignition switch, and the remaining black and red lines are usually connected to the pulse low-voltage line of the large wire package. The engine needle tachometer cable of a motorcycle is a flexible shaft type. When installing, first align the lower end of the needle tachometer cable with the fork of the engine needle tachometer drive gear shaft, then press the needle tachometer cable in, install the fixing screw, and then pull the needle tachometer cable along the frame to the right side of the instrument panel under the needle tachometer. Insert the upper end of the needle tachometer cable into the interface below the needle tachometer, and tighten the screw. Connect one end of the code table gear to the other end of the code table. One end of the gear connected to the code table is about to remove the code table teeth, which is the front wheel drum brake. Insert the square line in the code table line. One end of the code meter is inserted into the back of the pointer shaft of the code meter, and then there is a fixed metal cap with threads, which can be tightened. 

The needle tachometer can visually display the engine speed under various working conditions, allowing the driver to know the engine's operation at any time. By coordinating with the transmission gear and throttle position, it can maintain the optimal working state, which is beneficial for reducing fuel consumption and extending engine life. Watching the speed per hour should refer to looking at the pointer during your ride. Generally, motorcycles have two pointer gauges, one is the engine needle tachometer and the other is the speedometer. The speedometer (speedometer) is the one with two rows of numbers. When the pointer points to 50, it indicates that your speed is 50 kilometers per hour. The higher the engine needle tachometer of a straddle motorcycle, the higher the engine speed, and the higher the fuel consumption. But this is not absolute either, and the lower the engine speed, the more fuel-efficient it is. For example, when driving at an economic speed with low throttle, sometimes the fuel consumption may be slightly lower than when running at idle speed.
