harley davidson tachometer installation

• 2022-04-26

It's very simple. Just buy an electronic harley davidson tachometer and connect it. It is usually on the contact coil. Connect the speed line to the tachometer through the engine speed port. Or through the signal line of the ignition circuit to the tachometer, one ignition is one revolution. The first is mechanical, the second is electronic! There are two kinds of motorcycle engine tachometer, mechanical and electronic. The mechanical type is to connect the tachometer gear on the engine and the tachometer on the instrument through a flexible shaft meter line; The electronic type connects the tachometer and igniter to the high-voltage package through a speed measuring line (wire). However, due to different models, some connect the speed measuring line to other places, depending on the specific situation.

Fuel saving has nothing to do with idling. Harley's machine is the low idle machine in the motorcycle. If you measure Harley by car fuel consumption, Harley is completely drinking oil, but there is no comparability. As for engine oil, I usually use red line 20w50, more than 3 barrels, less than 4 barrels. Officials suggest changing it every 8k-10k km, but for domestic oil products, it's better to change it a little 5k-6k.

The idle speed of EFI vehicle is regulated by an idle motor. It is generally controlled by computer and does not need to be adjusted manually. I don't know what kind of idle speed you need to adjust. If the idle speed is unstable, it's best to go to a professional repair shop and find a maintenance technician, because there are many reasons for the unstable idle speed, not just the problem of the idle motor. It's best not to disassemble it yourself. When installing the motorcycle electronic tachometer, the green line is connected to the rack, the black line is connected to the positive output of the ignition switch, and the rest is generally connected to the pulse low-voltage line of the large wire package.

It is also possible that the engine tachometer line of the motorcycle is a flexible shaft type. During installation, first align the meter line at the lower end of the speed line with the fork of the driving gear shaft of the engine tachometer, then press the meter line in, and then install the fixing screw, and then pull the tachometer line along the frame under the tachometer on the right side of the instrument, insert the upper end of the meter line into the interface under the tachometer, and tighten the screw.
