The Two Brothers Racing Crew recommends attaching the JUICE BOX™ to the back of the shifter case using the velcro square provided. Then routing the wire plugs down through one of the holes in the frame between the seats. We also used the zip ties provided to keep the wires together once connected (See Fig. 5a, 5b).

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.

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.

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 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.

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

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) - Not Required

for this particular model.

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

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.

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

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.

no fuel will be added
