Review on 🔧 Timorn Tachometer: Waterproof Hour Meter for Small Engine - Ideal for Chainsaw, ATV, Motorcycle & UTV Engine (Black) by Jeff Driscoll

I use this on a Honda CB100 to diagnose misfires at high speeds; This might not be the best application as the RPM feature is slow to respond to gas bursts. Since it reads the pulses from the spark plugs, the meter reading can be inaccurate in the event of an electrical problem, although this can also be useful information. A motorcycle might not be the best use for it, but for an engine with a relatively constant throttle position, it should work just fine. Installation was as easy as the instructions say. The hour meter seems fairly accurate. Overall very good value for money.
