The JUICE BOX™ can be placed in the tail section or up

11.
by the speedo.

NOTE: Re check your wire routing and JUICE BOX™
location and make certain that in no way the wires can
come into contact with any moving parts or high heat
source and that the JUICE BOX™ is mounted in a way as
to not cause a handling problem with the machine.

Assembly is the opposite of disassembly.

12.

Start the bike. The green LED should scroll left to right and

13.
back for about 3-5 seconds and then go to 1-2 steady or
slowly flashing green LED’s. If the number 1 green LED
and number 8 red LED’s continue flashing after startup
or idling, an injector wiring error is indicated. Re-check
the wires from the JUICE BOX and make sure they are
connected to the proper wire of your bike’s stock harness.
MAKE SURE you have the correct wires selected in
the stock harness. DO NOT PROCEED UNLESS ABOVE
CONDITIONS ARE MET.

If the unit requir es cleaning , use a clo th that is only lightl y dampened with water or mild det ergent.

Cleaning

It is recommended that the pre-programmed settings of

1.
the Juice Box™be used. However, the Juice Box™ can be
adjusted to suit different engine modifications, states of
tune and environmental conditions. To begin this process,
press the mode button. To enter each successive mode, just
press the mode button again. Note that every mode will
be identifiable by the color(s) of the flashing LED(s) on the
LED display.
by an LED color or color combination.

as follows, respectively: Green, Yellow, Red, Green-Blue,
Yellow-Blue and Red-Blue.

2.

You are now ready to manually program each mode.
Consult the base settings supplied with the unit.

To program the Juice Box™, the bike must be running in
order to supply power to the Juice Box™.

Simply press the mode button to activate the first mode.
If at anytime you stay in an adjustment mode for longer
than 5 seconds without pressing any buttons, the Juice
Box™ will exit the adjustment mode and will return to the
operational mode.

To save settings in a particular mode press the MODE
button which goes to the next adjustable mode or wait for
the Juice Box™ to exit back to the operational mode.

The settings in each mode are adjusted by pressing the
(+) and (-) buttons located on the right and left side of the
mode button, respectively. For easy reference, the LEDs are
numbered 1 through 8. However, the LEDs can be adjusted
to the following positions: 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5,

5.5, 6, 6.5, 7, 7.5, 8. For example, in a particular mode, if LED
4 is flashing then the LED display is set to 4 in that mode. If
the (+) button is pressed once then LEDs 4 and 5 will flash
simultaneously and the LED display is set to 4.5. If the (+)
button is pressed once again, only LED 5 will flash and the
LED display is set to 5. The LED display can also be set
to 0.5 by pressing the (-) button and scrolling the colored
LED to position 1 and then pressing the (-) button once
more until the LED in position 1 is flashing twice as fast as
normal.

I.
additional amount of fuel added under cruise conditions.
A flashing green LED should appear on the LED display.
To add more fuel, scroll the flashing green LED to the right
using the (+) button. To add less fuel, scroll the flashing
green LED to the left using the (-) button. If you set the
flashing green LED to the 0.5 position on the LED display,
no fuel will be added to the stock fuel curve.

Note: In order for the Juice Box to meet emissions
requirements, a small portion of “The first mode (Green
Mode)” is non-adjustable. Operation of this mode remains
unchanged from the above instructions. However, during
vehicle operations a single green LED will slowly flash on
the LED display indicating that the vehicle is operating in
the Emissions Legal Zone and no modification to the stock
fuel curve is taking place.

II.
additional amount of fuel added during acceleration. A
flashing yellow LED should appear on the LED display. To
add more fuel, scroll the flashing yellow LED to the right
using the (+) button. To add less fuel, scroll the flashing

There are six modes that are distinguished

The 6 modes are

The first mode (Green Mode) represents an

The second mode (Yellow Mode) represents an

yellow LED to the left using the (-) button. If you set the
flashing yellow LED to the 0.5 position on the LED display,

no fuel will be added to the stock fuel curve.

III.

The third mode (Red Mode) represents an additional

amount of fuel added during full throttle conditions. A
flashing red LED should appear on the LED display. To add
more fuel, scroll the flashing red LED to the right using the
(+) button. To add less fuel, scroll the flashing red LED to
the left using the (-) button. If you set the flashing red LED
to the 0.5 position on the LED display,

to the stock fuel curve.

Note: If the flashing green, yellow and red LEDs in modes
1 through 3 (Green, Yellow and Red) are set to the 0.5
position on the LED display then the Juice Box™ will not
add any fuel to the bike’s stock fuel curve. This setting will
essentially turn off the Juice Box™ even though it is still
attached to the bike’s fuel injection system. The bike will
run as though the Juice Box™ is not installed. The Juice
Box™ LEDs will still operate normally even though no fuel
is being added.

IV.

The fourth mode (Green-Blue Mode) is an
adjustment to determine the point on the RPM range when
the cruise/Green Mode fuel turns OFF. A flashing green
LED appears on the LED display while at the same time a
flashing blue LED appears on the 8th LED. The cruise/Green
Mode fuel can be set to turn OFF during high cruise rpms at
a point selected by the user by adjusting the green LED in
this mode. The Green-Blue mode is RPM based only. Each
LED position represents a specific RPM on your bike. In this
case, LED 0.5 will turn OFF the cruise/Green Mode fuel at
2750 RPM and LED 8 will turn OFF the cruise/Green Mode
fuel at 4000 RPM. Each LED setting in between 0.5 and 8
will turn ON the cruise/Green Mode fuel in between the
above-mentioned RPM points. You can calculate what RPM
corresponds to what LED by interpolation. If during cruise,
the Green LED is solid, then the Green Mode is active;
Green Mode fuel is being added during cruise. If during
cruise, the Green LED is slowly flashing, then the Green
Mode is NOT active; Green Mode fuel is NOT being added
during cruise

V.
to determine the time when the acceleration/Yellow Mode
fuel amount turns on. A flashing yellow LED appears on
the LED display while at the same time a flashing blue LED
appears on the 8th LED. To increase the sensitivity and
therefore cause the Yellow Mode fuel to turn on sooner,
scroll the flashing yellow LED to the left using the (-) button.
To decrease the sensitivity and therefore cause the Yellow
Mode fuel to turn on later, scroll the flashing yellow LED to
the right using the (+) button.

VI.
to determine the time when the full throttle/Red Mode fuel
amount turns on. A flashing red LED appears on the LED
display while at the same time a flashing blue LED appears
on the 8th LED. To increase the sensitivity and therefore
cause the Red Mode fuel to turn on sooner, scroll the
flashing red LED to the left using the (-) button. To decrease
the sensitivity and therefore cause the Red Mode fuel to
turn on later, scroll the flashing red LED to the right using
the (+) button.

The fifth mode (Yellow-Blue Mode) is an adjustment

The sixth mode (Red-Blue Mode) is an adjustment
