how to install a tachometer rpm gauge

The revolution error will not be large. It is calculated by the magnetic steel boss. The idle speed of the scooter is about 2000 (not less than 2000. The oil pump pressure is not enough and the lubrication is not good). Your rpm is very normal. Many pedals in Guangyang and Sanyang in Taiwan start at 4000-4500rpm revolutions. The maximum speed of 100-125cc flat road is about 7000 rpm, and that of high cylinder pressure (such as Sanyang Hummer 125cc 7.5kW) can reach 8000 rpm. The torque and speed of the CVT transmission of the scooter depend on the number of revolutions, and the number of revolutions should be lower when blocking the scooter.

The 2400rpm of the cold car is normal, but it should be 1700-1800rpm when it is hot. It's normal that the maximum is more than 7000rpm. You think it can be tens of thousands! The motorcycles with tens of thousands of revolutions are all four valve motorcycles, and the compression ratio must reach more than 11:1. Among the Chinese pedals, only the Guangyang curve lover 150kcc version can reach 10000 turns, and the original manufacturer has a revolution meter.

If the motorcycle wants to install a tachometer rpm gauge, the induction line of the tachometer is usually connected to the line from the igniter to the high-voltage package, and some are connected to the output line of the magneto. Some motorcycles do not have a tachometer, and there is no place to install a tachometer line on the engine. If this kind of motorcycles need to install a tachometer rpm gauge, they can only install an electronic tachometer. Generally, electricity is obtained from the output line of the igniter or magneto coil.

Many motorcycles can change the engine oil every 2000 kilometers after the running in period. As long as it is genuine engine oil, it can be used. Generally, 10w-40 gasoline engine oil or motorcycle engine oil is used.

It is recommended to check the circuit or replace components. The tachometer can be removed. If it is a front wheel turbine, turn the front wheel to see if the soft axis rotates; If it is an engine turbine, start the engine to shift gear and check whether the soft axis rotates. Inspection method of tachometer: insert a small screwdriver into the connecting hole after removal, and turn the screwdriver to see whether the speed pointer works. Generally, there is no meter core for single sale. If it is determined that it is broken, it is recommended to replace it with a tachometer and reinstall it.
