Yamaha XVS1100L/LC V Star / DragStar 1100 1999–2000 Service Manual Set (P/N LIT-11616-12-63)

The supplement updates the base manual with changed specifications, cable routing, maintenance charts, wheel procedures, switch checks, and its own wiring diagram.

Additional manual required for complete A-series service: Yamaha also specifies the separate XVS1100AM/XVS1100AMC supplement, P/N LIT-11616-13-36 / Form 5KS-28197-E0. That publication is not included here.

PDF Search, Bookmarks, and Wiring Detail

Navigation and diagram labels: Text search is available in the supplement’s text sections, but not in the base manual. Embedded bookmarks cover both publications; two top-level entries have no page destination. Small labels in the main and supplementary wiring diagrams require zooming.

One printable, English-language PDF contains 385 pages, including both front covers and the supplement’s back cover. The two publications are combined in one file.

V-Twin Repair, Shaft Drive, and Electrical Diagnosis

The following selected coverage highlights outline the main workshop tasks. Further topics include exhaust-system checks and rear brake-light-switch adjustment.

• Engine repair: Step-by-step engine removal and installation, cylinder-head service, internal inspection, timing-gear work, clutch repair, and transmission and middle-gear procedures.

• Carburetion and tune-up: Carburetor disassembly and assembly, fuel-level adjustment, synchronization, throttle-position-sensor checks, compression testing, ignition-timing checks, and Air Induction System inspection.

• Brakes and chassis: Wheel and brake-disc service, brake-pad replacement, master-cylinder and caliper work, hydraulic bleeding, front-fork overhaul, steering-head service, and swingarm inspection.

• Shaft drive: Final-drive disassembly, ring-gear backlash measurement and adjustment, bearing service, pinion/ring-gear alignment, and drive-shaft installation.

• Electrical diagnosis: Circuit-based fault tracing for ignition, electric starting, charging, lighting, signals, fuel-pump operation, carburetor heaters, evaporative-emission components, and sensor self-diagnosis.

• Workshop references: Exploded assembly views, job-order charts, lubrication diagrams, cable routing, wiring diagrams, torque tables, wear limits, clearances, capacities, and electrical test specifications.

Yamaha wrote these manuals primarily for dealers and qualified mechanics; users need an understanding of motorcycle mechanics and the tools required for the work.

Engine Internals and Cylinder Timing

Teardown and inspection: Coverage includes camshafts and rocker arms, valves and guides, springs, cylinders, pistons and rings, crankshaft and connecting rods, crankcase separation, oil-pump inspection, and generator and starter-clutch service. Transmission checks address shift forks, the shift drum, shaft runout, and gear condition.

Assembly references: Front- and rear-cylinder timing references differ. The manual also covers connecting-rod bearing selection and middle-drive gear setup.

Hammering during piston-pin removal can damage the piston or pin; a dropped circlip can enter the crankcase. Lapping compound in the valve stem-to-guide clearance can damage both surfaces.

Carburetors, Maintenance, and Regional Differences

Adjustment procedures: Float and needle-valve inspection accompanies fuel-level work and throttle-position-sensor adjustment. The Air Induction System section includes an air cut-off valve section view and hose-routing references.

Routine service: Valve-clearance adjustment, idle and cable settings, engine and final-drive oil changes, spoke and wheel checks, battery testing and charging, fuse checks, and headlight alignment are covered. California-specific evaporative-emission parts, purge-hose routing, carburetor data, and electrical checks are identified separately.

Suspension and Final-Drive Service

Fork-leg disassembly, handlebar and steering-head work, rear shock removal and inspection, and swingarm bearing checks are documented. Shaft-drive troubleshooting includes oil-contamination and leak checks, with backlash and gear-alignment views supporting shim selection.

Support the motorcycle securely before engine, wheel, brake, suspension, swingarm, or shaft-drive work. Follow the manual’s specific warnings for brake fluid, battery charging, fuel handling, and rotating-engine tests.

Circuit Tests and Factory Tools

Fault isolation: Ignition, starting, charging, and fuel-pump circuit diagrams connect component tests with wiring checks, helping distinguish circuit faults from failed components before replacement. Self-diagnosis covers the throttle-position and speed sensors; starter-motor disassembly and inspection are also included.

Job planning: Exploded views identify replacement items, lubrication points, and torque callouts. Engine lubrication flow diagrams and complete cable-routing layouts support reassembly.

The tool lists provide U.S./Canadian and alternate numbers: vacuum gauge YU-08030-A / 90890-03094, compression gauge YU-33223 / 90890-03081, crankcase separating tool YU-01135-A / 90890-01135, valve spring compressor YM-04019 / 90890-04019, and final-gear backlash band YM-01230 / 90890-01230.

Preview: Valve Clearances and Ignition-Coil Testing

For the base models, cold valve-clearance specifications are 0.07–0.12 mm intake and 0.12–0.17 mm exhaust, with the piston at TDC on the compression stroke. These accompany the cylinder-specific adjustment procedure.

The base manual lists primary winding resistance of 3.57–4.83 Ω at 20°C (68°F) for the F6T541 ignition coil. Its ignition troubleshooting section explains the associated component test alongside switch and wiring checks.
