Searchable Service Text and Wiring Diagram Detail

Text search and diagram navigation: Service text is searchable, and embedded PDF bookmarks provide access to chapters, procedures and reference tables. Labels within the full wiring diagrams are image-based and are not searchable. Small wiring labels require zooming.

One printable English PDF is supplied in a ZIP archive. Its 633 pages include the original front matter, final model-application page, 11 blank pages and three pages marked “Dummy Page.”

DFI Fault Tracing, Engine Repair and Shaft-Drive Setup

The following selected contents outline the main workshop coverage. Other topics include windshield adjustment and saddlebag removal and installation.

• Periodic maintenance: Inspection and replacement schedules, fluid service, chassis lubrication, brake wear, steering checks, and fastener torque and locking-agent tables.

• DFI diagnosis: Step-by-step self-diagnosis procedures, service-code reading and erasing, fuel-pressure and flow tests, sensor checks, and ECU power-supply diagnosis.

• Engine and transmission repair: Engine removal, cylinder-head and piston work, cam-chain installation, crankcase separation, crankshaft inspection, and transmission disassembly and assembly.

• Clutch and shaft drive: Hydraulic clutch service, clutch-pack inspection, spring-plate-gap adjustment, bevel-gear bearing preload, backlash measurement, shim selection and tooth-contact checks.

• Cooling and lubrication: Cooling-system pressure testing, water-pump mechanical-seal replacement, thermostat inspection, oil-pump service and engine oil-pressure measurement.

• Brakes and chassis: Caliper and master-cylinder repair, brake bleeding, wheel-bearing replacement, front-fork overhaul, rear air-shock adjustment, and steering-stem and swingarm bearing service.

• Electrical troubleshooting: Charging and ignition tests, starter-motor disassembly, interlock checks, meter and warning-system diagnosis, and market-specific wiring diagrams.

Written primarily for trained mechanics in a properly equipped shop, the manual also supports owners undertaking basic maintenance and repair who understand mechanics, tool use and workshop procedures; advanced work requires the specified equipment and skills.

Maintenance Planning and Factory Reference Data

The maintenance chart separates the initial service from recurring mileage-based inspections and calendar-based replacements. Brake and clutch fluid, coolant, radiator hoses, O-rings, and fuel, brake and clutch hoses have distinct replacement schedules.

Component-specific torque tables identify locking agents, lubrication requirements, replacement fasteners and tightening sequences. Fluid specifications distinguish engine-oil refill conditions, coolant mixture requirements and temperature-dependent final-drive oil grades.

Mitsubishi Electric DFI and Electrical Diagnosis

The DFI chapter checks throttle, inlet-air pressure, atmospheric pressure, temperature, crankshaft and vehicle-down sensors, along with injectors, the fuel pump, ignition coils, ISC valves, the DFI relay, fuse and ECU supply circuits.

Service codes 11–15 cover principal sensor faults; 21–22 identify crankshaft-sensor faults; 31 covers the vehicle-down sensor; 41–42 the injectors; 45 the fuel pump; and 51–52 the ignition coils. ECU backup behavior is also explained.

The DFI Diagnosis Flow Chart and fuel-pressure tests help distinguish fuel-supply problems from electronic control faults. The DFI Wiring Diagram and ECU connector-terminal views support circuit tracing. The throttle sensor is factory-set; its checks do not constitute a separate adjustment procedure.

Electrical coverage extends to alternator-output specifications, regulator/rectifier tests, ignition peak-voltage checks, starter brushes and commutator inspection. Full wiring diagrams distinguish United States/Canada, Australian and other-market circuits, with European and California details where applicable.

Internal Engine Work and Hydraulic Clutch Service

Engine procedures cover camshafts, rocker arms, hydraulic lash adjusters, valves, guides, seats, cylinders, pistons and rings. Cam-chain installation and KACR inspection are included. Hydraulic lash adjusters maintain valve clearance automatically, so routine valve-clearance adjustment is unnecessary.

Crankcase work includes the crankshaft, connecting rods, balancer, transmission gears, shift drum and shift forks. The crankcase halves are machined as a matched set; excess liquid gasket near the oil-screen area can obstruct an oil passage and damage the engine.

Hydraulic wet multi-disc clutch coverage includes master and slave cylinders, line bleeding, clutch-pack inspection and spring-plate-gap adjustment. The manual relates insufficient gap to abrupt engine braking and rear-wheel hop, and excessive gap to clutch slip or a spongy lever.

Bevel Gears, Cooling and Chassis Repair

The final-drive chapter goes beyond oil changes, with pinion and ring-gear removal, bearing-preload adjustment and shim-based setup. Correct Tooth Contact Pattern and Incorrect Tooth Contact Patterns views support assessment of the drive and coast faces.

The ring and pinion are factory-lapped together; mixing gears or disturbing the shim relationship can produce incorrect contact, noise and gear damage.

The Coolant Flow Chart and Engine Oil Flow Chart trace circulation through their respective systems. Cooling procedures include radiator-cap testing and water-pump seal replacement. Chassis sections cover fork oil-level setting, rear air-shock inspection and replacement, steering bearings and brake hydraulic components. The Appendix adds cable, wire and hose routing and a system-based troubleshooting guide.

Specified Workshop Tools and Safe Support

Tool references include Fuel Pressure Gauge Adapter 57001-1593, Hand Tester 57001-1394, Needle Adapter Set 57001-1457 and Oil Pressure Gauge 57001-125 for diagnostic work.

Mechanical procedures identify Clutch Spring Compressor 57001-1162, Pinion Gear Holder 57001-1165 and Final Gear Case Holder 57001-1250, distinguishing operations that require dedicated fixtures.

Use a suitably rated lift and secure the motorcycle before wheel, suspension, engine or final-drive work. Observe the manual’s battery and live-circuit precautions during DFI and electrical testing.

Selected Fuel-Pressure, Oil-Pressure and Bevel-Gear Specifications

DFI fuel-pressure data specify 304 kPa (44 psi) immediately after key-on with the pump running and at idle. Residual pressure is 280 kPa (41 psi) after the three-second pump cycle stops, with pressure retention specified for about 30 seconds.

Engine oil pressure is specified at 340–440 kPa (50–64 psi) at 2,000 rpm with oil at 90°C (194°F).

Final bevel-gear backlash is 0.10–0.20 mm when measured at the ring-gear hub splines; the manual treats front bevel-gear backlash separately.
