Review on 🏍️ High-Performance SAMDO 6 Gear Universal Motorcycle Speedometer Tachometer: Digital Odometer, 199 KMH MPH, 14000RPM, Water Temperature, 1,2,4 Cylinder - Ideal for Carburetor Motors! by Jeff Drollinger

This is normal for the price. Speed calibration made no sense to me. I put it on a bike with a 21" front rim and ended up entering a calibration value of 016. I had to use GPS to find the baseline and then do some math to figure out what the value should be. be. Now that it's typed in, it works beautifully. Although he was running in a car that used to have a tachometer, the cable that powered the tachometer from the bike didn't work. I had to connect to the trigger coil to get the RPM readout. Before proceeding with the wiring I used a 12v battery to identify all the lights before soldering them on. It helped me to know where everything is connected. The neutral light and all gear indicators are reverse polarity which means the wire you connect for the neutral light actually goes to ground. On my bike, the neutral switch connects the neutral wire that goes to the light to ground. For that it worked great. The supplied schematics were pretty accurate. Only one cable was a different color than advertised. Also, he had no wire to take the temperature. It just wasn't the wiring harness. Also, I never set the flashing of the fuel gauge from scratch. I used appropriate resistance values on this cable to make it think it had a full tank, but no luck. I've only resigned myself to it blinking. Now that everything works, I'm mostly satisfied.
