2. MOUNT VAPOR:
4. TROUBLESHOOT ERRATIC TACH:
Vapor operates on the internal 3.0V watch type battery
(#CR2032). If possible, install Vapor to the vehicle’s
electrical system. Wiring to the vehicle enables a brighter
backlight, longer sleep timer, and enables the shift and
temperature indicator LED’s. Vapor is polarity independent
and has safeguards to avoid draining the vehicle battery.
See the POWER CONNECTION section for more info.
Vapor is made to be bolted to the vehicle. Use
the included handlebar mounts, or refer to the
manual.
See the TACH IGNITION SENSOR section for more information. If everything is working, but the tach is way off, then there’s too much
“ambient electrical noise”, or the tach sensor is installed incorrectly.
1. Try wrapping the tach sensor around the spark plug wire more or less times.
2. Avoid routing wires alongside other high-voltage wires that may cause noise interference.
3. Some kits include a “resistor tach sensor”. If there’s a lot of tach noise at a certain frequency,
the resistor may filter and smooth it out.

5. INDICATOR LIGHTS:
6. SLEEP MODE:
Vapor has two colored LED lights at the top. They are activated when tach or temperature goes above the thresholds to warn you about
potential problems with your vehicle. The left LED is yellow, the right LED is red. When the tach is over the rev limit the LED will flash, if the
temperature is high then the LED will turn on solid. Set custom thresholds in the DATA SETTING MODE. Set the thresholds to 0 to turn them off.
If Vapor sees no activity (either wheel movement or a button press) for 5 minutes, it will enter sleep mode and only display the clock. Sleep
mode will end when any activity is noticed. During sleep mode Vapor is using the internal battery and will not draw down vehicle power.

POWER AND TACH SENSORS
INSTALLS
POWER CONNECTION:
FOR USE ON 6-400 VDC/VAC SYSTEMS ONLY!
Vapor will operate in the range of 6-400 VAC/VDC, but will not draw enough power to
drain a vehicle battery. Use a volt meter to confirm 6-400 VDC/VAC. Vapor is polarity
independent, so it cannot be installed backwards.
Fuse: Introducing a fuse into the circuit before electronics is always a good idea.
Use a 1 amp fuse with Vapor (not provided).
System Tap: It is possible to tap into the vehicle electrical system anywhere in the circuit.
Possible points are at the lights, ignition, or CDI. When tapping into the electrical system,
connect to a circuit protected by fuse.
MX Bikes: Most do, but some motocross bikes do not have 12 volt power. If there is no
vehicle battery or capacitor, connect power wire to ignition power leads from stator.
Use caution, as this is a high voltage option.

If required, you may shorten the length of the ignition

casing to avoid damaging the inner red wire.
To install ignition sensor wire, wrap the
red part of the sensor wire around the
coil wire 5 times.

The Vapor sensors plug securely into

TEMPERATURE SENSOR
INSTALLS
TEMPERATURE SENSORS:
Most Vapor kits contain a model-specific temperature sensor. Installing the temperature sensor enables
temperature readouts on Vapor. Alternative sensors are available.
Vehicles cooled with water use sensors to measure the fluid temperature, while air-cooled machines take
the cylinder head’s temperature at the spark plug. The radiator fin sensor is the easiest installation for
water cooled applications.

more rapidly at high temperatures.

WHEEL SENSORS
INSTALLS
Some ATVs require
mounting the wheel
sensor directly to the
brake caliper.
Drill a 1/8” hole
through the caliper
mount, then use the
self-tapping screw to
secure the sensor.
BRAKE CALIPER WHEEL SENSOR
Brake Caliper

If the fork is close to
the brake rotor, then
the VHB fork sensor
can be used. Peel
and stick the sensor
to the fork.
Try to have the tip of
the sensor about 1/2
inch away from the
magnet in the rotor. Rotor Bolt Magnet
Some kits include
a metal C-bracket
to help mount the
sensor, as shown.
Use the jam nuts to
secure the sensor to
the C-bracket. Use
loctite rather than
over-tightening the
jam nuts.

with a rotor shield,
position the sensor

over-tightening the

ROTOR SHIELD WHEEL SENSOR
MAGNET INSTALLATION:
Install a magnet on the brake rotor to trigger
the speed sensor each wheel rotation.
Remove one of the stock rotor bolts and
install the magnetic rotor bolt as shown, do
not overtighten past 10 ft-lb of torque. If the
magnetic bolt will not work, the kit includes a
spare magnet that can be installed into one
of the rotor spaces. Use the included retainer
clip or epoxy such as JB Weld to secure. Magnetic Retainer or Spare MagnetMagnetic Rotor Bolt

MEASURE WHEEL SIZE:
WHEEL SENSOR TEST:
Test for correct sensor/magnet placement before permanently mounting.
1. Set the vehicle on a stand so that the front (left) wheel spins easily.
2. Plug the wheel sensor cable into the computer.
3. Install the magnetic bolt.
4. Hold the sensor in place on the caliper mount by hand. While someone
watches the computer, roll the wheel. If the computer does not register,
move the magnet or sensor and try again. There should be 1/2” or less
gap between the sensor and magnet.
Do not mount so that the magnet passes the middle section of the
sensor. Either the sensor will not register at all; or the sensor will
register twice, causing a “double trigger” effect (computer displays
twice the true speed.) If a double-trigger is unavoidable, divide the wheel
size setting in the computer by 2 to correct the problem.
Magnet Rotation Path
Knowing your exact wheel size it critical for the wheel sensor to calculate
correct speed and distance data.
When comparing calibration to GPS data, use a long straight section of road
with no tight corners or small vertical movements.
On a at surface, mark the tire sidewall and the ground with a marking pen. Roll the
wheel until the mark on the tire completes one revolution and is back on the ground. Mark
the ground at this location. Measure the distance between the marks on the ground in
millimeters (multiply inches by 25.4 to convert to mm). Use this number for your wheel size.
For accuracy, the rider’s weight should be on the bike when making the measurement.
Method 2: Rolling
Find the circumference of front wheel by measuring its diameter in millimeters.
Multiply the Wheel Diameter by 3.14. The result is your wheel size.
Method 1: Ruler
Enter the number you calculate from one of
the above formulas into setup mode.
Method 3: Distance Measurement
This is the most accurate method.
1. Set the wheel size to 2110mm (motorcycle) or 1675 (ATV).
2. Find a length of road where the distance is known.
3. Ride the distance, noting how far the computer reads (i.e. the road
is known to be 5 miles and the computer shows 4.95 miles.)
4. Use the numbers to solve for X in the following equation:
Wheel Size =
