INSTRUCTIONS
Calibration
1a. In 6th gear. Press and hold the UP or DOWN
button while you are riding until the 6th gear
indicator light comes on. Your bike must be
moving to adjust the speedometer.
1b. Follow a vehicle going at a set speed or time
yourself riding one mile so you know what
your speed is. A GPS or Dyno are other good
ways to determine your speed.
2. Press and hold the UP or DOWN
button while you are riding to change the
reading on the speedometer until the accurate
speed is displayed. Your bike must be moving
to adjust the speedometer.
3. After the 1097-0001 has detected that no
buttons have been pushed for 10 seconds,
a new calibration will be stored.
Installation
2004 & up Sportsters and
all other models 2007 & up
1. Find the speed sensor wires coming from the
sensor. (The speed sensor is below the battery at
the back of the transmission nearly centered in the bike.)
2. After locating the speed sensor, follow the wires
up to the ECM. At an accessible point, cut the
wires and solder in the 1097-0001 as shown in
the diagrams on the following pages.
3. For 2007 model bikes with cruise control
You have to make the cut prior to where the white/
green wire is Teed into the cruise control module,
this is usually located about 3-4” after the speed
sensor plug at the sensor.

hanging the gear ratio on some models will make the speedometer read
incorrectly. When the speedo reads incorrectly it can incapacitate the 6th gear
indicator light and cruise control. The 1097-0001 will make it possible to adjust
an electronic speedometer with the stock electric speed sensors to the correct reading.
The 1097-0001 has an adjustable range of correction from x2.84 times (more than
double) to x0.502 times (half). Calibration is set using the two button switches.
Press the UP button to increase the speed. Press the DOWN button to decrease
the speed. The 1097-0001 has an internal memory that stores the calibration when the
bike is off, or if the 1097-0001 is unplugged.(Unit must remain on vehicle after recalibration.)
Kit Number
1097-0001
Note:2004 and up Big Twin Motorcycles use a data bus to send information to the speedometer. The
1097-0001 needs to correct speed information before it goes into the ECM. To correct a speedometer
on a 2004 or newer bike, the 1097-0001 needs to be connected between the speed sensor and the
ECM to function properly .
