Anyone created a wiring diagram for electronic speedo and tach of a 4lo?
Thanks

Nope, but if its a Koso then I expect that the tach will run off one of the white wires from the stator. I ran mine like that on my Koso Dual EGT dash on advice from Koso America, who I bought the instruments off.
The rest is easy, most need just need a +12v, switched 12v, dash lights, and earth.

If i remember rightly the the tacho wire is blue/yellow and can be taped directly to the coil feed or spiral wound around one of the HT leads.

My koso tacho worked by connecting to the coil feed but once running it would become irattic and didn’t seam to be very responsive. I was advised to fit a koso filter which I did. This connects to one of the ht leads or a coil feed, works spot on now.

Most of the clocks i fitted were for 50cc bikes. |
