FUEL LINE

FUEL FEED HOSE

Remove the main pipe side cover (page 23-25). Check the fuel feed hose for deterioration, damage or leakage. Replace the fuel feed hose if necessary (page 24-54). Also, check the fuel feed hose fittings for leakage. Install the removed parts in the reverse order of removal.

ENGINE IDLE SPEED

IDLE ADJUSTING SCREW

If the engine must be running to do some work, make sure the area is well ventilated. Never run the engine in an enclosed area. The exhaust contains poisonous carbon monoxide gas that may cause loss of consciousness and may lead to death. Run the engine in an open area or with an exhaust evacuation system in enclosed area. NOTE: • Inspect and adjust the idle speed after all other engine maintenance items have been performed and are within specifications. • The engine must be warm for accurate idle speed inspection and adjustment. Warm up the engine for about ten minutes. Connect a tachometer. Turn the idle adjusting screw as required to obtain the specified idle speed. IDLE SPEED: 1,400 ± 100 min–1 (rpm)

TECHNICAL FEATURE ABSOLUTE PRESSURE FUEL SUPPLY SYSTEM The fuel delivery system consists of the following components: fuel tank, fuel suction filter, fuel pump, internal pressure regulator, fuel feed hose and injector. This system is eruipped with the absolute fuel pressure. There is no external fuel return hose or vacuum pressure regulator with this system. The fuel pressure in the fuel delivery system is regulated by the internal pressure regulator and always kept absolute; 294 kPa (3.0 kgf/cm2, 43 psi). The internal pressure regurator returns the fuel by opening a valve when the fuel pressure increases more than 294 kPa (3.0 kgf/cm2, 43 psi). This system optimizes injection volume by the ECM control.

PGM-FI SERVICE INFORMATION GENERAL • Be sure to relieve the fuel pressure while the engine is “OFF”. • Before disconnecting fuel feed hose, relieve pressure from the system by disconnecting the quick connect fitting in the fuel pump (page 24-54). • Bending or twisting the control cable will impair smooth operation and could cause the cable to stick or bend, resulting in loss of vehicle control. • Work in a well ventilated area. Smoking or allowing flames or sparks in the work area or where gasoline is stored can cause a fire or explosion. • Do not snap the throttle valve from full open to full close after the throttle cable has been removed. It may cause incorrect idle operation. • Seal the cylinder head intake port with tape or a clean cloth to keep dirt and debris from entering the intake port after the throttle body has been removed. • Do not damage the throttle body. It may cause incorrect throttle valve. • Prevent dirt and debris from entering the throttle bore and fuel feed hose, clean them using compressed air. • Always reset the TP sensor when you remove the sensor unit from the throttle body. • The throttle body/sensor unit is factory pre-set. Do not disassemble in a way other than shown in this manual. • Do not loosen or tighten the white painted nut of the throttle body. Loosening or tightening them can cause throttle body malfunction. • Always replace the packing when the fuel pump is removed. • The programmed fuel injection (PGM-FI) system is equipped with the Self-Diagnostic System described (page 2431). If the malfunction indicator lamp (MIL) blinks, follow the Self-Diagnostic Procedures to remedy the problem. • When checking the PGM-FI, always follow the steps in the troubleshooting flow chart (page 24-36). • The PGM-FI system is provided with fail-safe function to secure a minimum running capability even when there is any trouble in the system. When any abnormality is detected by the self-diagnosis function, running capability is secured by making use of the numerical values of a situation preset in advance in the simulated program map. The engine does not start, if the injector or ignition pulse generator has a problem. • Refer to PGM-FI system location (page 24-29). • A faulty PGM-FI system is often related to poorly connected or corroded connectors. Check those connections before proceeding. • When disassembling the programmed fuel injection parts, note the location of the O-rings. Replace them with new ones upon reassembly. • Use a digital tester for PGM-FI system inspection. • Refer to procedures for fuel level sensor inspection (page 24-77).

PGM-FI TROUBLESHOOTING Engine won’t to start • Intake air leak • Fuel contaminated/deteriorated • Fuel supply too low – Faulty fuel pump operating system (page 24-58) – Faulty fuel supply system (page 24-54) – Clogged injector filter – Sticking injector needle Engine stall, hard to start, rough idling • Intake air leak • Fuel contaminated/deteriorated • Fuel supply too high – Faulty fuel supply system (page 24-54) • Fuel supply too low – Faulty fuel supply system (page 24-54) – Clogged injector filter • Idle speed misadjusted • Idle air passage clogged • Low cylinder compression

24-28

Backfiring or misfiring during acceleration • Fuel supply too low – Faulty fuel supply system (page 24-54) – Clogged injector filter • Ignition system malfunction (page 22-110, 24-74) Poor performance (drive ability) and poor fuel economy • Air cleaner element contaminated • Fuel supply too low – Faulty fuel supply system (page 24-54) – Clogged injector filter • Ignition system malfunction (page 22-110, 24-74) • Low cylinder compression

PGM-FI SELF-DIAGNOSIS INFORMATION

MALFUNCTION INDICATOR LAMP (MIL)

SELF-DIAGNOSTIC PROCEDURE Place the motorcycle on its centerstand. NOTE: The malfunction indicator lamp (MIL) will start blinking the ignition switch to “ON” or engine revs are below 2,000 min–1 (rpm). In any other conditions, the MIL will illuminate and stay on. Turn the ignition switch to “ON”. The malfunction indicator blinks, note how many times the MIL blinks, and determine the cause of the problem (page 24-34). If the MIL does not light or blink, the system is normal. If you wish to read the PGM-FI memory for trouble data, perform the following:

To read the stored problem data Turn the ignition switch to “OFF”. Remove the front top cover (page 23-24). Disconnect the connector cover from the data link connector (DLC).

MIL CODE INDEX • The PGM-FI malfunction indicator lamp (MIL) denotes the failure codes (the number of blinks from 0 to 54). The MIL has two types of blinks, a long blinks and short blink. The long blink lasts for 1.3 seconds, the short blink lasts for 0.3 seconds. When one long blink occur, and two short blink, that problem code is 12 (one long blink = 10 blinks, two short blink = 2 blink). Then, go to the flow chart and see problem code 12. • When the Engine Control Module (ECM) stores some failure codes, the MIL shows the failure codes in the order from the lowest number to highest number. For example, when the MIL blinks once, then blinks seven times, two failures have occurred. Follow the flow chart for failure codes 1 and 7.
