Old man on a bike
I know some of you R3T owners have talked about putting a tachometer on your bike. I've been looking and decided on the Koso BA035103 in chrome...It also comes in black. I spent most of the afternoon working on it, but I'm fussy. I used a Kuryakyn P-Clamp to get it mounted where I wanted it. I tied it into my center coil as it was the easiest to get to. A couple of adjustments and it seems to works fine from the get go. I'm posting this video. As you can see I didn't get it done till after dark. I'll post a few more shots tomorrow in the daylight after I get all the wires neatly dressed and everything buttoned up.
Well, I guess I can't post a video of it in action...I guess a picture or two will have to do for now.

The tachometer has four wires, three in one group and one separate. The three 22ga wires are power-switched; power-unswitched, and ground. There is a long single wire, and this is for the pulse. I tied the switched wire into the position light that was in the headlight shell before the LED conversion. I ran a new wire for unswitched back to the auxiliary distribution panel under the seat between the rear fender and battery. The tachometer default count setting is one cylinder, and this is what works on the Rocket. Physically, the tachometer has two small buttons on the bottom, and if one looks closely with good eyes or a magnifying glass, one can see labels "SELECT" (left) and "ADJUST" (right). Having hooked up the sense wire (long blue) using the supplied pigtail (they call it "RPM Wire (Type B)") to the middle coil as described above, must be changed to "Lo". So there are three settings available on the tachometer, in this order: 1) Number of pistons; 2) Hi-Lo sense; 3) backlight brightness setting.
To enter the set mode, with power on the tachometer, push both buttons and hold for three seconds, and you will see the hand of the tachometer move to 500. This is the default setting of one spark for each two revolutions of the engine, and what works on the Rocket Touring. So leave that as is, and press the "SELECT" button once to change to the sense setting. Press the "ADJUST" button once. This should change from the default "Hi" to "Lo". You're done with settings, so push and hold the "SELECT" button to put the tachometer back into the operating mode.
If for some reason, the tachometer is still not reading, repeat the steps above.
