Super 9 tachometer troubles

[winner3ty]

Hey my super 9 has some weird tachometer gremlins, usually it reads 0 Rpm when running or off, or 12K+ on or off, with or without a battery, (pics included) will tightening some sort of tachometer screw fix this? or is it like a pinched wire?



No battery

Winner3ty, You can check the wires going to the coil make sure they have a good connection. Sometimes the tachometer can go out of whack due to a failing cdi. If it turns out to be a electrical issue in which you cannot fix within the tachometer, here is a used one for $25
