2-1/16" tachometer 3-1/3" tachometer

Our tachometer have 2-1/16" and 3-1/3" size , it is 52mm and 85mm. When starting, it is best to use first gear. Due to the transmission ratio, the torque in first gear is the strongest, making it the most suitable for starting, carrying weight, and climbing. Starting in first gear is also the easiest, and the engine load will be the smallest, making it the least likely to harm the car. But also due to the transmission ratio, refueling in first gear will cause the car to jump and stopping when refueling. Therefore, as long as you start in first gear, you should immediately switch to second gear or higher. Starting in second or higher gear will increase the engine's load and make it more difficult, which will have adverse effects on the cylinder block, piston, valve system, clutch, etc. 

If you refer to "high-speed starting" as high-end starting, then a higher engine speed is required. Before releasing the clutch, increase the throttle to increase the speed, and then release the clutch, which is similar to starting from first gear, but the engine speed should be higher, otherwise it is easy to stall the car. 

The 2-1/16" or 3-1/3" tachometer represents the engine speed and provides numbers on it × 1000 indicates that the pointer points to a speed of several thousand revolutions per minute at that time. Experienced individuals can better grasp the working status of the engine and control its speed. Generally, the speed of small displacement engines is controlled below the red line of 10000 revolutions per minute. It adds a speed line to the rocker arm inside the valve generator and connects it to the instrument itself. The faster the engine speed, the higher the 2-1/16" 3-1/3" tachometer. You can tell by opening the wire that the speed wire is running at high speed when the engine starts! 

What does a car, motorcycle, or odometer mean by "one above" or "one below"? How much is this for me? What do you think of the tachometer? On board, The top is the speed, kilometers per hour, and the bottom is the total mileage. I have already driven 19520 kilometers, and there is no running in period for such a broken car. There is no tachometer at all. That is the engine speed, usually around 5000 or 6000 revolutions, to help you understand the engine speed during jerking and driving, and not to let the engine exceed the load. The tachometer unit is 1/min × 1000, which displays the number of thousand revolutions per minute of the engine.
