Step 1: Identify the key components that complete our Superbike kit: You should have 2 lines (front kit), 1 double banjo bolt and 2 lower adapters. There are also a total of 7 washers. 5 will be used, and 2 are spares. We strongly suggest having a professional mechanic install these brake lines; all other installations VOID warranty. Inspect your brake system after every race. Step 2: To ensure no paint damage from a brake fluid spill, completely cover the front end of the bike. This process is messy, and brake fluid WILL drip! Step 3: Uninstall stock hoses; be aware of how the stock system was routed in case you need to re-install it. Step 4: Install the Galfer adapters onto the right and left calipers. Thread each adapter into the calipers with one washer, and torque at 12 to 13 ft pounds. (See picture S4) Step 5: Install the right and left lines to the calipers, using the shorter line on the right side. These lines will travel from the master cylinder to the calipers; a double banjo bolt (see picture S5) is included to run two lines down. The positioning sequence on the master cylinder is as follows: Master cylinder, washer, straight banjo (from right line), washer, 12-degree banjo (from left line), washer, and double banjo hex. Double banjo bolt torque level is 12 FT Pounds. ( See picture S6) Make sure that the 90-degree fittings on each caliper are pointing away from the bike just a little bit (see pictures S7 through S9 of calipers) . Thread each banjo end into the adapter, and torque to 6 ½ Ft pounds. Before you proceed to the next step, please check for clearance of the lines. Compress the front end to make sure that the lines are not binding with anything. When the front end is fully extended or fully compressed, double check that the lines are traveling correctly and clear from any obstructions. Once the lines have been checked for clearance, we recommend using a zip-tie to bring the lines together about an inch above the lower triple clamp area. (Picture S10) Step 6: Bleed brake system according to owner’s manual, and build appropriate pressure. Finishing with DOT 4-brake fluid is recommended.

The launch of the sixth generation of Gsxr marked a shift in Suzuki’s emphasis on two fronts. One, the Gsxr 1000 now took the upper hand in the development stakes. Historically, the Gsxr 750 led the march-arriving first, gaining the most recent technology, absorbing the lion’s share of corporate pride-but by 2003 the Gsxr 1000 was in the lead. Two, the Gsxr 1000 represents another, more subtle shift for Suzuki engineering, in which the designers-the lucky guys who get to clothe these amazing machines-have more freedom of expression. With this generation, the designs turned edgier, sharper, more aggressive looking than ever. What’s more, the Gsxr 1000 K3 would be the proving ground for a host of changes brought to the Gsxr 600 and Gsxr 750 for 2004. In fact, nearly every upgrade to the smaller bikes appeared on the Gsxr 1000 a year before. But the real impetus for driving the Gsxr 1000 to the head of development and, indeed, shortening its development cycle was competition both on the track and in the showroom. For the track, it was understood that Superbike racing would revert to allowing 1000 cc four-cylinder bikes in place of the 750s that had been the limit since 1982. In 2002, Yoshimura and Mat Mladin barely lost the AMA Superbike crown to Nicky Hayden aboard the Honda RC5!. But it would be the RC’s swan song of competitiveness with the change to 1000 cc fours. To keep speeds in check, the AMA Superbike rules would require 1000 cc fours to have some additional limitations compared to the twins and triples. For example, “Cylinder heads may be ported and machined, but altering of valve angles will not be permitted; aftermarket valves, springs, retainers, and other valve-train components will be permitted; valves must be stock size and same basic material as original equipment; aftermarket camshafts will be permitted, but earn lift and resulting valve lift must be no greater than stock. “In addition, the “stock crankshaft must be retained, The only allowable modifications are balancing, polishing of bearing surfaces and attachment of accessory drives. Homologated transmission gear sets (one optional set of ratios per approved model) will be permitted. Optional sets will be price-controlled and must be available to any legitimate AMA Superbike competitor. Homologated fuel-injection throttle-body assemblies (one optional type per approved model) and aftermarket airboxes will be permitted. Modifications to throttle bodies will not be permitted. Optional throttle bodies will be price-controlled and must be available to any legitimate AMA Superbike competitor.” The thinking was simple: keep the liter bikes from sucking through massive throttle bodies, and the horsepower might not (and, it was hoped, would not) go through the roof. In preparation for racing, Suzuki moto wanted to make a host of small changes to the Gsxr 1000, but its motivation was also to keep the bike at the forefront of open-class street bikes. Suzuki engineers knew that Honda and Kawasaki were readying all-new models-the CBR 954 RR and the ZX 9 R had long since been vanquished-and rumor had it that Yamaha was ready with yet another push with the R1.It was the right time to make alterations to the Gsxr 1000. Heading the list was, as one might expect, a revised engine.

PRECAUTIONS IN SERVICING When handling the component parts or servicing the FI system, observe the following points for the safety of the system . ELECTRICAL PARTS CONNECTOR/COUPLER • * When connecting a connector, be sure to push it in until a click is felt. •With a lock type coupler, be sure to release the lock when isconnecting, and push it in fully till the works when connecting it. • * When disconnecting the coupler, be sure to hold the coupler body and do not pull the lead wires . • * Inspect each terminal on the connector/coupler for looseness or bending. • * Inspect each terminal for corrosion and contamination. The terminals must be clean and free of any foreign material which could impede proper terminal contact . •Inspect each lead wire circuit for poor connection by shaking it by hand lightly. If any abnormal condition is found, repair or replace. •When taking measurements at electrical connectors using a tester probe, be sure to insert the probe from the wire harness side (backside) of the connector/coupler . 0 4 40 O/ 40 16~ Id •When connecting meter probe from the terminal side of the coupler (connection from harness side not being possible), use extra care not to force and cause the male terminal to bend or the female terminal to open . Connect the probe as shown to avoid opening of female ter- minal. Never push in the probe where male terminal is supposed to fit. •Check the male connector for bend and female connector for excessive opening. Also check the coupler for locking (looseness), corrosion, dust, etc . FUSE • * When a fuse blows, always investigate the cause correct it and then replace the fuse . • * Do not use a fuse of a different capacity . • * Do not use wire or any other substitute for the fuse . ECMNARIOUS SENSORS •Since each component is a high-precision part, great care should be taken not to apply any sharp impacts during removal and installation. • * Be careful not to touch the electrical terminals of the ECM . The static electricity from your body may damage this part . FI SYSTEM DIAGNOSIS 4-3
4-4 FI SYSTEM DIAGNOSIS • When disconnecting and connecting the ECM, make sure to turn OFF the ignition switch, or electronic parts may get dam- aged. • * Battery connection in reverse polarity is strictly prohibited . Such a wrong connection will damage the components of the FI system instantly when reverse power is applied . • * Removing any battery terminal of a running engine is strictly prohibited. The moment such removal is made, damaging counter electromotive force will be applied to the ECM which may result in serious damage.

The installation of the AFR Tuner should be done by experienced technicians only. Always disconnect the battery from the motorcycle before making any modification to the wiring harness. Remove the negative terminal from the battery before starting the installation work. The quality of the installation work greatly affects the reliability of the AFR Tuner and the motorcycle. Work precisely and very carefully when modifying the wiring harness of the vehicle. Always double check that the wire you are about to cut or tap into is the correct one. The ECM or the AFR Tuner can be destroyed by a faulty installation. 3.2. Installing the AFR Tuner to the wiring harness 3.2.1. Main cable The AFR Tuner connects to the motorcycle through its Main connector . Figure 2 shows the wiring diagram and the necessary modifications, which needs to be made when installing the unit into the fuel injection system of the motorcycle. Information about the ECM terminal numbers and wire colors for some popular motorcycles can be found in Chapter 6 . The best location for installing the AFR Tuner main unit is at the passenger seat area of the motorcycle mounted in the trunk space or on the subframe under the fairing, as this place provides protection from engine heat and the weather. Electrical contact between the metal casing of the AFR Tuner and the rear subframe must be prevented by using insulating material, such as the included self adhesive velcro strips. If necessary use some cable ties to secure the unit in place. The installation of the AFR Tuner into the wiring harness involves tapping into some wires and cutting others while connecting the two ends to the AFR Tuner. The harness modifications are best done near the ECM, since most of the wires can be found there. Part of the wiring modifications are related to connecting the AFR Tuner in-line between the ECM and the fuel injectors. In such cases when the motorcycle is equipped with primary and secondary injectors the AFR Tuner has to be installed on the primary injectors, which operate under all engine conditions. Correct grounding of the AFR Tuner is very important for electrical noise reduction. The above mentioned insulation of the metal case from the motorcycle frame is necessary for the same reason, which is to avoid the forming of a ground loop. An even more important requirement is the correct connection of the three ground wires of the AFR Tuner. As shown on Figure 2 , these three wires must be led out separately to the ECM and connected together at same point where the ECM ground wire is tapped into. This point should be as close to the ECM terminal as possible. For best quality of the electrical contacts all connections should be done by soldering and covering the exposed part of the wire with heat shrink tubing. For reliability reasons do not use clip on type wire taps
