I installed a mini chrome tach from drag specialties. I have it on the bars just to the right of center. It really looks cool but only gives me a 1/2 rpm reading. I have it connected to the #1 coil, 12v. for power and ground as per the instructions. Nobody has been able to explain adequately to me how to install the adapter that supposedly will give me a true reading. Since the #1 coil (right side of rear cyl. head) only fires every 720 degrees it's obvious that I'll only get the 1/2 reading (450 rpm at idle). I'll figure it out one day. At least it lets me know what gear I'm in -- if I'm reading about 1,300 rpm at 50mph (2,600 rpm) I know I'm in 4th; if I'm reading about 1,300 rpm at about 62 mph I know I'm in 5th. I was thinking of connecting another tach wire to the #2 coil (right side of front cyl. head) to see if that would correct the situation, but I don't want to screw anything up electrically! I'm just waiting for now for someone to be successful with a Raider tach!
