clicked they don't cost too much and there are many different series. For the oil, for rpm, for fuel, and what else? But they don't look so good, kinda cheap quality looking. You like em?
Usually, the input to the tachometer comes from the output of the CDI going to the coil.
As for the temperature, it measures the coolant or water temp range is if you can find from 0 to 100 deg celsius you can use it.
One way to hook up the thermocouple or the sensor is to cut the return line of the radiator hose that's the top hose and put a piece of pipe with the same diameter as the hose and there should be a hole with a thread so that you could screw the sensor.
hi guys, i just suggest to use KOSO digital tachometer, it's an engine pulse tacho, it's accurate and easy to install, i use the TEMP& TACHO 2-in-1, i'd love to post picture but how can i do that ?
