4 T-Tap Connectors (1 spare)
2 Zip Ties

KAWASAKI VULCAN 1500 DRIFTER Fi
Instruction Manual >
Read all instructions carefully and completely before installing your new Fi2000 module.
It is recommended that a qualified mechanic or technician install this product.
1. Remove the seat by unbolting the two hex bolts attaching the seat.
2. Remove the right side panel by unscrewing the phillips head screw attaching the panel.
3. Remove the battery cross brace by unbolting the phillips screw. See figure 1.
4. Locate the ECU next to the battery and lift it straight up and out to locate the BLUE w/RED stripe wire
and the BLUE w/GREEN stripe wire on the harness going to the white connector for the ECU. Attach
a t-tap connector to each of these wires about an inch from the connector on the ECU. See figure 1
5. Plug the Fi2000 modules BLUE w/RED stripe and BLUE w/GREEN stripe wires to the
corresponding ECU wires with the t-tap connectors and replace the ECU to its original location.
Route the wires as shown in figure 1. Note: Make sure not to attach the t-tap connectors closer
than 1 to the stock ECU connector.
6. Locate the RED w/BLUE stripe wire in the wiring loom on the right side of the motorcycle where the
side cover was (the wire comes out of the fuse box) Attach a supplied t-tap connector on that wire.
Refer to figure 1
7. Route the Fi2000s RED w/BLUE stripe wire behind the right frame rail and attach it to the t-tap
connector installed in step 6 and the BLACK wire to the negative post of the battery. Refer to figure 1
8. Remove the backing from the Velcro and attach the Cobra module vertically at the back left corner
just in front of the frame cross member as shown in figure 1. Make sure the module is low enough to
clear the seat.
9. Reinstall the battery cross brace and phillips screw making sure not to pinch any wires between the
battery and brace.
10. Before re-installing the seat and side cover, verify your connections. Remove the door from the
Fi2000 box to expose the LEDs. Verify the wire connections by (1) turning the ignition on, prior to
starting, and see if all three LEDs are on steady. If you have no light, either your ground connection
(BLACK wire) is not solid or, (more likely) your RED w/BLUE stripe wire connection is incorrect. You
have either tapped on the wrong wire or the tap has not made contact. (2) After achieving a steady
light from all three LEDs, start the motorcycle and let it idle, the green light should now be the only
LED on. If all three LEDs are still on after start up, your BLUE w/RED stripe wire connection is
incorrect; if all three LEDs are flashing, your BLUE w/GREEN stripe wire connection is wrong. Again
verify correct color and tap contact. Reattach the door when finished. Note: Make sure the ignition
is turn off before changing any connection.
11. Re-install the seat and side cover with the stock hardware.

ADVANCED TUNING
Your Cobra Fi2000 fuel injection module has been tested and preset for best function and drivability on a
stock motorcycle with a Cobra exhaust. The Fi2000 does however, have 3 important adjustments that
allow you to tune the module for optimum performance, especially if you have performed other changes to
your motorcycle. These adjustments also allow you to resolve drivability issues if our stock settings are
not exactly right for your bike. Make sure your motorcycle is up to normal operating temperature (15
minutes of riding should be sufficient) before making any adjustments. Remove the cover to expose the
pots shown in figure 2.

GREEN LED POT (left pot) - this adjustment affects idle and cruise fuel. If you have cruising issues, this
is where you would try a different setting. Generally, surging and uneven running while cruising is a lean
fuel condition, so try adding a small increase in fuel by turning the adjustment clockwise with a small flat
blade screwdriver a 1/2 position. Test drive the bike to feel an improvement and only increase the setting
until the surge goes away. Also, backfiring or popping on trailing throttle is generally a lean symptom (or
an exhaust gasket leak). Try the same small increases as above just until the backfiring goes away.

YELLOW LED POT (middle pot) - this adjustment affects acceleration and power fuel. If you have a
hesitation or bogging on acceleration, this is where you would try a different setting. Aftermarket air
cleaner assemblies generally lean out fuel mixtures, so try small clockwise increases as above until a
smooth acceleration returns.

RED LED POT (right pot) - this pot controls the top end (power) fuel. On most bikes the factory gets the
top end fuel right, as emissions testing is not done there and most exhausts by themselves won't
dramatically change that requirement. Hi-Flow air cleaner assemblies, especially those that remove a lot
of restriction, can significantly alter the high R.P.M. demand for fuel. This is where you would use the red
led pot. Starting at the 3 position, to be safe, test ride the motorcycle up to redline and adjust the pot until
you feel the best performance.


TROUBLE SHOOTING
If you have any problems refer to note 10 in the main body of these instructions.
