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

Before installing the Fi2000R it is recommended that the gas tank be low on fuel.

1. Remove both seats; remove the fuel tank console. Next, remove the fuel tank by removing the
bolts and lifting the tank enough to gain access to the white wire connectors and dry brake fuel
line. Unplug the wire connectors by pressing the tabs inwards. Disconnect the dry brake fuel line
by depressing the two gray tabs.

2. Loosen the clamp on the air intake boot just enough to release the boot from the throttle body
assembly to lift upwards. The boot does not have to be fully removed.

3. Temporarily position the FI2000R module by the battery, and route the wire harness forward
underneath the starter solenoid cable and into the notch in plastic cover, (Fig.1.) Continue routing
the harness under the frame at the rear of the fuel tank, and continue it up past the left side of the
throttle body assembly.

4. Push the air intake boot to the right to gain access to the front fuel injec tor. Release the black
injector connector by squeezing the two side tabs inward and pulling it away at the same time,
(Fig. 2.) Now connect the forward Fi2000R matching connector to the injector and then connect
the original connector to the corresponding Fi2000R connector. Replace the air boot and tighten
the clamp.

5. Locate the rear injector on the throttle body housing and repeat the procedure in Step 4. When
finished, make sure the wire harness does not foul any throttle cable linkage. Zip tie the harness
as indicated in, (Fig. 3.) Reinstall the fuel tank by reconnecting the white wire connectors and dry
brake fuel line to the fuel tank.

6. Connect the Fi2000R ground wire (black), to the negative post of the battery and attach the
Fi2000R module to the top of the plastic panel with the supplied Velcro, (Fig. 1.) Before
reinstalling the seats verify all connections are made properly.

7. Remove the door from the Fi2000R module to expose the LED’s. Verify the wire connections by
(1) turning on the ignition while watching the 3 LED's. They will all light up for a few seconds, then
go off. This is correct. If you don't see lights, make sure the side stand is up, bike is in neutral,
clutch is in and handle bar 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.--(Continued next page)

7 Cont. (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
and install seat. Note: Make sure the ignition is turned off before changing any
connection.

ADVANCED TUNING

The Fi2000R 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 slip-on mufflers. 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, other with race or competition baffles. Full exhaust systems offer even
greater variation in construction, features and performance. The Fi2000R 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 Fi2000R. These suggestions should be
followed step by step and help you achieve success.

1. Start with the base setting, even if you have a full exhaust system. 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 will 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 Fi2000R may have the ability to
adjust for.
