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.

FUEL PUMP The electric fuel pump is mounted at the bottom of the fuel tank, which consists of the armature, magnet, impeller, brush, check valve and relief valve . The ECM controls its ON/OFF operation as controlled under the FUEL PUMP CONTROL SYSTEM . When electrical energy is supplied to the fuel pump, the motor in the pump runs and together with the impel- ler . This causes a pressure difference to occur on both sides of the impeller as there are many grooves around it . Then the fuel is drawn through the inlet port, and with its pressure increased, it is discharged through the outlet port . The fuel pump has a check valve to keep some pressure in the fuel feed hose even when the fuel pump is stopped . Also, the relief valve is equipped in the fuel pump, which releases pressurized fuel to the fuel tank when the outlet of the fuel pressure has increased up to 450 -600 kPa (4.5- 6.0 kgf/cm2,64- 85 psi) . Relief valve Brush , ∎ I,’ Check valve Magnet L Armature When the impeller is driven by the motor, pressure differential occurs between the front part and the rear part of the blade groove as viewed in angular direction due to fluid friction . This process continuously takes place causing fuel pressure to be built up . The pressurized fuel is then let out from the pump chamber and discharged through the motor section and the check valve . FUEL SYSTEM AND THROTTLE BODY 5- 3 Inlet port I I Impeller 5-4 FUEL SYSTEM AND THROTTLE BODY FUEL PRESSURE REGULATOR The fuel pressure regulator consists of the spring and valve . It keeps absolute fuel pressure of 300 kPa (3.0 kgf/cm2,43 psi) to be applied to the injector at all times . When the fuel pressure rises more than 300 kPa (3 .0 kgf/cm2, 43 psi), the fuel pushes the valve in the regulator open and excess fuel returns to the fuel tank . 90 Spring 02 Valve FUEL INJECTOR The fuel injector consists of the solenoid coil, plunger, needle valve and filter . It is an electromagnetic type injection nozzle which injects fuel in the throttle body according to the signal from the ECM. When the solenoid coil of the injector is energized by the ECM, it becomes an electromagnet and attracts the plunger. At the same time, the needle valve incorporated with the plunger opens and the injector which is under the fuel pressure injects fuel in conic dispersion . As the lift stroke of the needle valve of the injector is set constant, the volume of the fuel injected at one time is determined by the length of time during which the solenoid coil is energized (injection time)
