Hey guys i have been wanting a tachometere on my bike for somewhile so yesterday i decided to take an instriment cluster from a dash and remove the tachometer, my plan to put it on my bike! So i get the tach out and take off the circuit board so i am left with the 3 terminals. Next step was to solder 2 wires on the cdi and one on the white wire for the purpose of figuring out which went were. I tried it out most of the ways just instantally killed the engine but one position actually brought the tach up to 1 but it never moved just sat there and shook. Anyone know how to properly hook a tachometer to one of theses bikes? I know it wont be accurate but it will keep me happy! THanks guys
