Does anyone know how to take the face off of the tach? I have been frustrated by my tach not working. It worked when I got the bike, but stopped soon after. I got to looking at it the other day and realized that the reason it isn't working is that the indicator is sitting BELOW the little stop that holds the indicator just below zero when the motor is off. I have no idea how this happened. is it possible to take it apart? I have considered drilling a small hole into the tach from near the bottom and sticking something small in there to push the indicator to the proper side of the stop. Is this the best solution?
