Instruction Manual >

It is recommended that a qualified mechanic or technician install this product.

Before installing the Fi2000 it is recommended that the gas tank be low on fuel.

1. Remove the M6 bolts securing the main seat and remove seat. Remove the left side cover to allow

access for the Fi2000 harness routing.

2. Remove the bolt securing the rear of the tank and prop the tank up at the rear for extra access to fuel

injectors.

3. Place the Fi2000 in the under seat area and route the harness forward under the front seat mount, see

Figure 1. Route up the center frame tube toward injectors along the left side.

4. Disconnect air recirculation hose to gain access to stock fuel injectors, see Figure 2.

5. Note which stock injector connectors belong to front and rear injectors. Disconnect the stock injector

connector from the front cylinder and connect the longer female Fi2000 connector to that injector –
connect corresponding male Fi2000 connector to stock female connector (removed from front
cylinder). See Figure 3. Note: (Angled needle nose pliers will aid in removing stock connectors.)

6. Disconnect the stock injector connector from the rear cylinder and connect the shorter female Fi2000

connector to that injector – connect corresponding male Fi2000 connector to stock female connector
(removed from rear cylinder injector), see Figure 3. Make sure all connectors are fully engaged and
seated.

7. Reconnect air recirculation hose. Pull slack out of harness and pull excess slack to rear of harness.

8. Remove the Phillips screw attaching cover over battery. Lift cover rearward to access battery

terminals. Attach the black ground cable to the NEGATIVE post of the battery. See Figure 1. Close
battery box cover and install Phillips screw. Install supplied zip tie to harness in location shown.

9. Velcro the Fi2000 box on top of the frame rail behind the battery box cover and verify your

connections. Remove the door from the Fi2000 box to expose the LED lights and pot settings. Verify
the wire connections by (1) turning on the ignition while watching the 3 LEDs, confirm that all 3 LEDs
light up and remain on. If you don't see lights, make sure the sidestand is up, bike is in neutral, clutch
is in and handlebar engine switch is set to run. If you still have no lights, re-check that all connectors
are fully engaged and the ground wire is connected correctly. (2) After achieving a steady light from all
three LED’s, start the motorcycle; the green light should now be the only LED on. If all three LED’s are
still on after start up, verify you have attached the injector connectors correctly. Reattach the access
door when finished. Note: Make sure the ignition is turned off before changing any connection.

10. Once all connections have been verified, lower the fuel tank into proper position and install bolt.
Reinstall seat and make sure all bolts are properly tightened.

11. Reinstall left side cover.

ADVANCED TUNING

The Fi2000 has the ability to efficiently tune the EFI system on your motorcycle for slip-on or full
exhaust systems. It comes pre-set from the factory for popular brand name full exhaust systems.
Both dyno testing and on-road exhaust gas analysis have been used to develop the best base
settings for drivability and power.

Not all slip-on mufflers flow exactly the same. Some eliminate power valves and others don’t. Some
are made with street baffles, others with race or competition baffles. Full exhaust systems offer even
greater variation in construction, features and performance. The Fi2000 has the ability to tune the EFI
system on your motorcycle to any of these exhausts by applying a logical and systematic approach to
altering the base settings supplied with your Fi2000. These suggestions should be followed step by
step and help you achieve success.

** Only attempt adjustments on a fully warmed motor **

1. Start with the base setting in Figure 4 if a full exhaust system is installed. If a full exhaust system
is installed in combination with a Cobra PowrFlo™ Air Intake System the same setting will be
adequate, please visit: www.cobrausa.com for system details. Refer to Step 2 if the stock
exhaust is installed or a slip-on muffler is being used to determine the proper pot settings. Adjust
and test only ONE adjustment pot at a time until you are happy with the result.

2. Start with the left hand or green light pot. This adjustment works either from idle or above idle
(varies with bike) to a R.P.M. of about 5000 (also varies with bike) while the bike is driven at a
steady throttle or slowly increasing throttle. This is the cruise range and is where the emissions
leanness creates issues like choppy on-off throttle application, surging, and backfiring on trailing
throttle.

3. Turn this pot back to zero, and make one position increases until you feel the best performance in
this range. Do this test a few times to make sure you have it right.

4. The middle or yellow pot is an engine load- triggered fuel adding adjustment. A rapid increase of
the throttle at any R.P.M. will add additional fuel and as long as that predetermined load is
present, fuel will continue. As engine loads increase in higher gears the acceleration fuel will stay
on longer and be more effective. Starting with the base setting, test ride the motorcycle in 4th or
5th gear and perform moderately fast roll-on throttle from a repeating standard R.P.M. or speed.
Increase the pot one position at a time and stop as soon as you don’t feel any improvement.

5. The right hand or red pot is for the fuel setting required when the engine is maximizing its R.P.M.
and power delivery. This pot is similar to the main jet in a carburetor. It will take a combination of
a minimum R.P.M. and a predetermined amount of engine load to initiate this fuel. The
straightaway on a racetrack or an inertia dyno are the best places to set this pot. Full exhaust
systems of high quality construction increase flow characteristics and may increase fuel demands
over our base settings. Also, air filters specifically designed for higher than stock airflow can
create need for higher fuel setting. Try an additional one-position pot setting at a time.

6. Camshaft changes or major air box modifications can alter an engine’s volumetric efficiency and
create a greater demand on the engine’s fuel system than the Fi2000 may have the ability to
adjust for.
