1997 Yamaha XVS 650 V-Star/Drag-Star Factory Service Manual & Supplement (P/N LIT-11616-11-16, LIT-11616-11-21)

This Yamaha XVS 650 V-Star/Drag-Star set pairs the XVS650AK(C) Service Manual, P/N LIT-11616-11-16 (first edition, August 1997), with the XVS650K(C) Supplementary Service Manual, P/N LIT-11616-11-21 (first edition, December 1997). The K(C) supplement is used together with the main manual.

Navigation and wiring detail: Embedded PDF bookmarks cover the main chapters and many service sections, including the supplement. Text search is unavailable. Small labels in the main wiring diagram need enlargement; some shaded system circuit diagrams have grainy labels that remain difficult to distinguish when enlarged.

• Engine repair: Engine removal, crankcase separation, cylinder-head and valve service, crankshaft inspection, and reassembly supported by exploded-view diagrams.

• Clutch and transmission: Wet-clutch repair, primary-drive inspection, shift-fork and shift-cam checks, transmission assembly, and starter clutch inspection.

• Shaft drive: Middle drive gear shim selection, universal-joint service, final drive/ring gear positioning, and final gear backlash adjustment.

• Carburetion and emissions: Mikuni BDS28 carburetor overhaul, synchronization, fuel-level adjustment, throttle position sensor testing, and air induction system servicing.

• Chassis repair: Front fork disassembly and assembly, hydraulic brake bleeding, master-cylinder and caliper service, steering head bearing replacement, and swingarm inspection.

• Electrical diagnosis: Ignition, starting, charging, lighting, fuel pump, and carburetor heater tests, with circuit diagrams and TPS self-diagnosis.

Written primarily for Yamaha dealers and qualified mechanics, this manual assumes a working knowledge of motorcycle repair and access to the specified service tools.

Model Codes and Supplement Coverage

The supplement supplies K(C)-specific chassis specifications and cable routing, plus fuel-tank, seat, headlight, front-fork, and steering-head procedures. Its different front-wheel, fork, and front-brake data help you match parts and service specifications to the correct configuration before repair.

SOHC V-Twin, Clutch and Transmission Repair

Periodic maintenance covers valve clearance adjustment, ignition-timing checks, compression testing, and lubrication schedules. Internal engine coverage extends to valve guides and seats, piston/ring inspection, oil-pump clearances, and crankshaft bearing selection.

Clutch and transmission sections detail push-rod inspection, gear engagement, and assembly orientation. Component torque tables include the primary drive gear nut and middle drive pinion gear nut, alongside lubrication diagrams, fluid capacities, and wear limits.

Yamaha cautions that interchanging connecting rods and their bearings can upset oil clearance and damage the engine.

Middle Gear and Final Drive Setup

Shim calculations use markings on the gears and housings. Final-drive procedures cover bearing replacement, ring-gear positioning, and thrust-washer selection, with dedicated measurement tools such as the YM-33222 middle gear backlash tool and YM-01231 final gear backlash band.

The middle-gear section warns that hammering the universal joint can distort the driven-pinion collapsible collar and change its specified spinning torque.

Carburetors, Fuel Delivery and Emissions

Fuel-system repair covers diaphragms, jets, float chambers, and TPS resistance testing and adjustment. The AIS section explains reed-valve and air cut-off valve operation; California-specific routing identifies the evaporative-emission canister and rollover valve.

Electrical Circuits and Fault Tracing

Diagram coverage includes the Ignition System, Electric Starting System, Charging System, Fuel Pump System, and Carburetor Heater System circuit diagrams, plus the complete XVS650AK(C) Wiring Diagram.

Test charts identify connector terminals and wire-color codes. Starting-system checks distinguish neutral, clutch, and sidestand interlock faults from starter or relay faults. Self-diagnosis addresses TPS faults indicated by the engine warning light, with separate harness and sensor checks.

Brakes, Suspension and Steering

Chassis coverage also addresses wheel bearings and static balance, brake-disc and drum inspection, rear shock absorber preload adjustment, and swingarm pivot checks. Rear shock procedures cover inspection and replacement; the pressurized shock body is not treated as a rebuildable assembly.

Working on motorcycle mechanical and electrical systems involves inherent risks. Follow Yamaha's precautions for brake service, electrical testing, and supporting the machine.

Combined PDF and Included Supplement

One printable, English-language 357-page PDF contains the 323-page main manual and 32-page supplement, including their original cover and introductory pages. Two additional pages, the illustrated opening cover and closing Yamaha parts-and-accessories page, are already included in that total.
