1 - 7 GEN INFO FEATURES Fuel pump The fuel pump, which is mounted in the fuel tank, draws the fuel directly from the tank and pumps it to the injector. A filter that is provided in the fuel pump prevents any debris in the fuel tank from entering the fuel system downstream of the pump.
1 - 8 GEN INFO FEATURES Pressure regulator It regulates the fuel pressure that is applied to the injectors th at are provided in the cylinders in order to maintain a constant pressure difference with th e pressure in the intake manifold.
1 - 9 GEN INFO FEATURES Fuel injector Upon receiving injection signals from the ECU, the fuel injector injects fuel. In the normal state, the core is pressed downward by the f orce of the spring, as illustrated. The needle that is integrated with the bottom of the core keep s the fuel passage closed.
1 - 10 GEN INFO FEATURES Crankshaft position sensor The crankshaft position sensor use s the signals of the pickup coil that is mounted on the right side of the crankshaft.
1 - 11 GEN INFO FEATURES Cylinder identification sensor The cylinder identification sensor is mounted on the exhaust head cover of the #4 cylinder. When the exhaust cam of the #4 cylinder ro tates and the lift of the cam passes by the sensor, th e sensor generates a signal and send s it to the ECU.
1 - 12 GEN INFO FEATURES Throttle position sensor The throttle position sensor measures the intake air volume by detecting the position of the throttle valve. It detects the mechanical angle of the throttle valve through the positional relationship between the moving contact that moves in unison with th e throttle shaft and the resistor board.
1 - 13 GEN INFO FEATURES Intake air pressure sensor and atm ospheric pressure sensor • Intake air pressure sensor The intake air pressure sensor is used for measuring the intake air volume. The intake air volume of every intake stroke is proportionate to the intake air pressure.
1 - 14 GEN INFO FEATURES Coolant temper ature sens or The signals from the coolant temperature sensor are used primarily for making fuel volume compen- sations during starting and warm-up. The coolant temperature sen sor converts the temperature of the coolant into electrical signa ls and sends them to the ECU.
1 - 15 GEN INFO FEATURES O 2 sensor The O 2 sensor has been adopted to enable the catalyst to fun ction at a high degree of efficiency by maintaining the air-fuel mixture near the stoichiometric ratio (14.
1 - 16 GEN INFO FEATURES Lean angle cut-off switch The lean angle cut-off switch stops the supply of fuel to the engine in case the moto rcycle overturns. When the motorcycle is in the normal state, the cut-off switch outputs a constant voltage of approxi- mately 1.
1 - 17 GEN INFO FEATURES FUEL INJECTION SYSTEM Operation and control The fuel injection timing, injection duration, ignition timing, and the coil energizing duration are con- trolled by the ECU.
1 - 18 GEN INFO FEATURES Determining the final injection dura tion The intake air volume d etermines the basic injection duration. However, at a given intake air vol- ume, the volume of fuel that is required varie s by the engine operating conditions such as accelera- tion or deceleration, or by weather conditions.
1 - 19 GEN INFO FEATURES Composition of final injection duration 1 Injection at start *1 2 After-start enrichment *2 3 Warm-up enrichme nt *3 4 Acceleration compen- sation *5 5 Oxygen feed back *6 6 F.

1 - 22 GEN INFO FEATURES • Starting cylinder control 1 Injectors #1,4 2 Injectors #2,3 3 Starting async hr o- nous injection 4 Group injection È Cylinder identification sensor É Crankshaft positio.
1 - 23 GEN INFO FEATURES • Warm-up enrichment When the coolant temperature is low, a warm-up coefficient is applied in accordance with the sig- nals from the coolant temperature sensor in order to effect fuel enrichment.
1 - 24 GEN INFO FEATURES • Acceleration enrichment Acceleration enrichment is provided in accordan ce with the signals fro m the throttle position sensor. As the rider operates the accelerator to accelerate th e motorcycle from a constant speed, the throt- tle position sensor actu ates in unison with the accelera tor.
1 - 25 GEN INFO FEATURES • Deceleration control Deceleration control is effe cted in accordance with the signals from the throttle position sensor. As the rider operates the accelera tor to decelerate the motorcycle that is in motion, the th rottle position sensor acutates in unison with the accelera tor.
1 - 26 GEN INFO FEATURES THREE-WAY CATALYTIC CONVERTER SYSTEM System outline This is a highly efficient exhaust gas cleaning system that effects air-fuel control throu gh a joint effort by the FI system, O 2 sensor, and the three-way catalytic conver ter system.
1 - 27 GEN INFO FEATURES Functions of components Catalyst Because the conditions in which NOx is generated are directly opposed to those of CO and HC, there is a limit to the extent to which the concentration levels of these harmful elements can be reduced in the combustion stage.
1 - 28 GEN INFO FEATURES Large amounts of b oth CO and HC are generated when t he mixture is rich (as indicated by insuffi- cient O 2 region A ). Conversely, large amounts of NOx are generated when the mixture is lean (as indicated by excessive O 2 region B ).
1 - 29 GEN INFO FEATURES Air-fuel ratio compensation equipment An O 2 sensor is provided in the exhaust pipe upstream of the catalyst, to enable the catalyst to operate at a high degree of efficiency. The O 2 sensor detects th e level of concentration of the oxy- gen remaining in the exhaust gases.
1 - 30 GEN INFO FEATURES AIR INDUCTION SYSTEM The air induction system (AI system) introduces fresh air into the exhaust port in order to b urn the unburned gas (wh ich is present in the exhaust g as) in the exhaust pipe. The burning of the unburned gases in this manner enhances the efficiency of the catalyst and results in cleaner exhaust gases.
1 - 31 GEN INFO FEATURES COMPONENTS 1.Air cut-off valve The air cut-off valve consists of a plunger that is mo unted inside the core of a solenoid coil, and a valve at the end of the plunger for o pening and clo sing the a ir passage.

The "Barbarian Jumper Mod" The "Barbarian Jumper Mod" Index Home Tom Barber (aka Barbarian ) and Dwayne Verhey (aka Torch ) from the FJROwners online forum figured out how to enable a North American spec'd FJR1300 to have it's EFI's CO setting adjusted, like the European and OZ/NZ models allow.
The "Barbarian Jumper Mod" First, remove the seat and two left sidecovers. As with the dash panels, Yamaha used a variety of fasteners on this job, including Allen head fasteners, push-pin fasteners, and 1/4 turn Philips head fasteners. See your owner's manual for a more complete description of removing each.
The "Barbarian Jumper Mod" Next, remove the airbox cover. At least all 4 of these are the same 1/4 turn fastener. Unfortunately, the one indicated by the screwdriver is recessed and a PITA.
The "Barbarian Jumper Mod" With the covers out of the way, the ECU is now accessible. Squeeze the black latch on the top of the connector as you pull it out of the ECU. On the underside of the connector are 3 white bars. Using a fingernail or http://www.
The "Barbarian Jumper Mod" small screwdriver, push the left one (as pictured) in about 1/32". This unlocks the wires in the connector. Pin #27 is the 5th from the left on the bottom row. It houses a yellow wire with a red stripe -- 1/2 of the Barbarian Jumper.
The "Barbarian Jumper Mod" Using a small piece of stiff wire (I used some .030 MIG wire, but a paperclip or safety pin would probably work) gently push up from the ECU side of the connector to lift the wire to pin 27 and the white plug in pin 25.
The "Barbarian Jumper Mod" The plug is small. Very small. And bouncy. It can travel a surprising distance when deflected off the airbox. If you drop it you are in for more fun than a snipe hunt. Do not ask me how I know this. Use tweezers. Put the plug in pin 27.
The "Barbarian Jumper Mod" pictured) white bar on the top of the connector down until flush (about 1/32") It does not take a lot of force, so if it doesn't want to go you probably have a wire pulled slightly out. Make sure all the wires in the left 1/3 of the connector are fully seated and try again.
The "Barbarian Jumper Mod" Nonetheless: all the standard disclaimers apply: Do this at your own risk. I am not responsible if you let the smoke out of your ECU. YMMV. Etc. -- Torch. Copyright © 2003, by H. Marc Lewis, Tom Barber, and Dwayne Verhey.
Installing Riv-Nut ports in the FJR's Headers Installing Riv-Nut ports in the FJR's Headers Index Home On 03/05/03 Dwayne Verhey (aka Torch ) from the FJROwners online forum wrote this Web page describing how to install " Riv-nuts " into the FJR1300's header pipes.
Installing Riv-Nut ports in the FJR's Headers This is a riv-nut tool. Similar to a standard pop rivet gun, but with interchangeable adapters and anvils sized for the insert being installed. The appropriate adapter is screwed into the tool, followed by the corresponding anvil.
Installing Riv-Nut ports in the FJR's Headers First a hole is drilled into the pipe where the port is required. European and Oceanic models have ports installed from the factory.
Installing Riv-Nut ports in the FJR's Headers Here the riv-nut is assembled on the tool and inserted into the hole ready to go. One squeeze of the handle is sufficient. Attempting to compress the riv-nut further will only strip the threads. As described earlier, unscrew the tool from the insert using the removal knob.
Installing Riv-Nut ports in the FJR's Headers The end result. The upper portion of the riv-nut has been mushroomed firmly against the wall of the pipe, following the curve, providing a threaded port. I chose 1/4"-20 NCT aluminium inserts for this example.
Installing Riv-Nut ports in the FJR's Headers The hole is sealed with a bolt when not in use. As can be seen from this picture, the bolt may protrude into the pipe unless cut to length.
Installing Riv-Nut ports in the FJR's Headers When cutting a thread, it's a good idea to temporarily install a nut first. Cut the thread off beyond the nut, then wind the thread past the end of the nut.
Installing Riv-Nut ports in the FJR's Headers The trimmed bolt no longer protrudes into the pipe. http://www.micapeak.com/bike/FJR1300/howto/rivnut.
Installing Riv-Nut ports in the FJR's Headers In an effort to reduce any possible restriction, I tried cutting 1/2 the threaded portion of a riv-nut off before installing it. The threads stripped out before it fully mushroomed, resulting in this failed installation on the right.
