Review on 🕒 Hardline Products HR-8061-2 Hour Meter/Tachometer for Twin-Cylinder Engines, Black by Wade Brooks

I wanted to use this to see how my RPMs develop alternately on my bike. But the readings jump sharply, not stable at all. The wire is too short. There are no instructions anywhere on their website as to what you should do. There should be instructions on what size and type of wire to use. I added a wire that was almost the same size as the wire's OD and soldered the connections together. Most of them know that for $29 the tiny amount of wire they give won't work for most setups. What a cheap company that doesn't supply enough cables. I'm not the first customer with this problem. It seems that lengthening the wire would not take away from their gains.
