Yamaha XJR1300(L) 1999 Service Manual Set (P/N 5EA3-AE1)

Both supplements are intended for use with the included base manual. The SP supplement supplies revised rear-suspension specifications, while the P supplement documents model-specific service changes.

Coverage: The included publications do not provide model-by-model repair coverage for every XJR1300 from 1995 through 2006. Match the motorcycle to the listed model codes and the applicable supplement.

PDF Search, Bookmarks, and Wiring Detail

Search and diagram detail: Text is searchable across the service chapters; some covers, dividers, and labels embedded in diagrams are not searchable. Small wiring labels are clear when enlarged. Base-manual and combined-file section bookmarks are usable. In the separate 2002 supplement, the main section bookmarks lead to the contents page; its wiring-diagram links work.

The ZIP contains three printable English PDFs totaling 773 PDF pages, including overlapping base and P-supplement material. This total includes four original cover pages, six blank pages, and one additional introductory page in the 383-page combined file.

Engine Overhaul, Carburetor Service, and Electrical Diagnosis

The following is a selected content overview, rather than a complete table of contents. Further topics include exhaust-system inspection and cable lubrication.

• Engine overhaul: Step-by-step engine removal and installation, camshaft timing, cylinder-head and valve work, piston inspection, crankcase separation, and crankshaft/connecting-rod service.

• Clutch and transmission: Hydraulic-clutch repair, starter-clutch inspection, oil-pump service, shift-mechanism checks, and gearbox inspection and reassembly.

• Carburetors: Mikuni BS36 removal and disassembly, jet and passage inspection, float/fuel-level setup, synchronization, fuel-cock testing, and throttle-position-sensor adjustment.

• Wheels and brakes: Wheel and brake-disc inspection, static balancing, master-cylinder and caliper repair, and hydraulic brake bleeding.

• Suspension and final drive: Front-fork disassembly and seal replacement, steering-head inspection and adjustment, swingarm and rear-shock inspection, and drive-chain adjustment and alignment.

• Electrical systems: Ignition, starting-circuit cutoffs, charging, lighting, signaling, fuel-gauge diagnosis, starter-motor repair, and A.C. generator service.

• Workshop references: Component-specific torque tables, clearances, wear limits, fluid and lubrication data, exploded assemblies, cable-routing views, and electrical test specifications.

Yamaha prepared these manuals primarily for its dealers and qualified mechanics, assuming an existing understanding of motorcycle repair and the appropriate workshop equipment.

Internal Engine Work and Routine Service

Bearing selection and assembly: The engine chapter explains Plastigauge clearance checks and color-coded crankshaft-journal and connecting-rod bearing selection. Job-order charts accompany exploded views, with symbols identifying replacement parts and lubrication points. Together, these references support planning the parts, tools, and inspection work required for an overhaul.

The camshaft-installation cautions explain how crankshaft movement can disturb valve timing and cause damage. Separate bearing cautions address the risk of engine damage when selected journal or big-end bearings are interchanged.

Maintenance and fault finding: Routine-service sections add valve-pad selection tables, ignition-timing and compression checks, hot-engine oil-pressure testing, suspension setup, sealed-battery charging information, and headlight aiming.

The troubleshooting chapter addresses starting and idle faults, poor medium- and high-speed running, shifting and clutch complaints, overheating, weak braking, fork problems, unstable handling, and lighting or signaling failures.

BSR37 Carburetors and the 2002 Service Changes

The P supplement provides BSR37 carburetor specifications alongside revised engine, chassis, electrical, maintenance, torque, and cable-routing data. Its air-induction coverage includes flow/no-flow illustrations and checks for the reed valves, hoses, pipes, and air cutoff valve.

Revised front brake master-cylinder installation and rear-caliper component layouts are documented separately from the base arrangements. Carburetor-heater troubleshooting covers the relay, thermo switch, heating elements, and circuit wiring. These distinctions help identify which supplementary data applies before selecting parts or test procedures.

Circuit Diagrams, Self-Diagnosis, and Special Tools

Electrical references include ignition and electric-starting circuit diagrams, engine-lubrication flow diagrams, harness and hose routing views, and separate 1999 and 2002 EUR/AUS wiring diagrams. Tachometer-based self-diagnosis is limited to the throttle-position-sensor and ignition circuits, with display sequences and associated fault tracing.

Named Yamaha tools include vacuum gauge 90890-03094 for synchronization and valve spring compressor 90890-04019. Other references identify fork-seal driver weight 90890-01367 and attachment 90890-01374, clutch holding tool 90890-04086, and ignition checker 90890-06754.

Brake, hydraulic-clutch, fuel-system, battery, and internal-engine work can leave the motorcycle unsafe when required procedures or final checks are missed, so work beyond the user's training or equipment should be referred to a qualified technician.

Compression and Fuel-Sender Test Examples

For the XJR1300(L), the compression-test section gives a standard pressure of 1,050 kPa at 400 r/min at sea level, with the engine warmed before testing.

Fuel-gauge diagnosis specifies sender resistance of 4–10 Ω with the float up and 90–100 Ω with the float down, both at 20°C. The section includes the sender connections and a separate gauge-response check.
