2008 Yamaha XV17AWX(C), XV17ASX(C), XV17ATX(C), XV17ATSX(C) Service Manual (P/N LIT-11616-21-68)

Yamaha’s 2008 Service Manual for XV17AWX(C), XV17ASX(C), XV17ATX(C), and XV17ATSX(C), P/N LIT-11616-21-68, is the first edition dated February 2008. It covers the U.S., California, and Canadian configurations identified in the model specifications.

Searchable Text, Bookmarks and Wiring Detail

Search and diagram detail: The PDF includes searchable text and embedded bookmarks for the main chapters and repair sections. Small wire-color codes and connector labels require zooming in the densely labeled circuit diagrams.

One printable English-language PDF contains 413 pages, including the original front and rear covers and six blank pages. The final color wiring diagram is included in the same file.

Engine Overhaul, Chassis Service and FI Fault Tracing

These selected topics cover major workshop tasks; the manual also explains instrument brightness adjustment and front-wheel static balancing.

• Engine repair: Step-by-step procedures for engine removal, camshaft and valve-train service, cylinder and piston inspection, crankcase separation, and reassembly.

• Clutch and drivetrain: Friction-plate inspection, clutch assembly, transmission and shift-fork checks, plus transfer gear case and oil-pump service.

• Fuel injection: Meter-based diagnostic mode, fault-code interpretation, sensor and actuator tests, pressure-regulator checks, and throttle-position sensor adjustment.

• Brakes and suspension: Front-fork overhaul, brake-caliper and master-cylinder service, hydraulic bleeding, steering-head adjustment, and swingarm linkage inspection.

• Belt and wheel service: Drive-belt inspection and adjustment, pulley replacement, wheel-bearing installation, and procedures distinguishing cast-wheel and spoke-wheel configurations.

• Electrical troubleshooting: TCI digital ignition, starting and charging tests, system-specific circuit diagrams, connector references, and a color wiring diagram.

Written primarily for Yamaha dealers and their qualified mechanics, this manual assumes familiarity with motorcycle mechanics and the techniques needed for maintenance and repair.

Valve-Train, Lubrication and Internal Engine Work

The valve-train section explains the role of the hydraulic valve lifters, when manual clearance adjustment is needed, and how front- and rear-cylinder timing references differ. Lifter bleeding, camshaft-journal inspection, rocker-arm measurements, and valve-seat checks extend the coverage beyond routine tune-up work.

Cylinder and piston inspections include wear limits and clearance measurements. Connecting-rod bearing selection uses crankshaft and rod markings together with Plastigauge checks. Exploded diagrams and job charts identify assembly relationships, lubrication points, and parts requiring replacement.

The rear cylinder-head cover has limited frame clearance, creating a risk of its bolts scratching the rocker arms or other engine parts during removal. The lubrication section also warns that unsuitable oils or additives, including oils labeled “Energy Conserving II,” can cause wet-clutch slippage.

Separate procedures cover the engine oil pump’s feed and scavenging sections and the transfer gear oil pump. Factory torque tables distinguish fastener sizes and assemblies, including cylinder-head nuts and the middle drive gear nut, rather than treating them as interchangeable specifications.

Chassis Differences and Reassembly References

The XV17ATX(C) uses spoke wheels and tube-type tires; the other covered variants use cast wheels and tubeless tires. Rear-pulley instructions distinguish these configurations, while fork service specifies bushing replacement, seal orientation, and oil-level measurement conditions.

Rear-shock coverage includes removal, inspection, preload adjustment, and linkage service. Yamaha warns against opening the nitrogen-charged shock absorber.

The engine oil lubrication chart, lubrication diagrams, and cable-routing illustrations provide workshop references for maintenance and reassembly. Routing details show how control cables, fuel lines, brake hoses, and the main harness are positioned. Hydraulic brake work requires the manual’s fluid-handling precautions and final brake-operation checks before riding.

Fuel-System Tests and Electrical Fault Isolation

The FI explanation relates sensor inputs to injection duration and timing through the MITSUBISHI FUA0027 ECU. Repair sections cover the throttle body, pressure regulator, injectors, and air induction system, with separate California canister checks.

Fault-code tables connect symptoms with probable causes, diagnostic checks, and reinstatement methods. For an intake-air-pressure fault, they distinguish electrical faults from a detached, kinked, or obstructed sensor hose, helping technicians investigate the cause before replacing components.

Starting circuit cut-off operation diagrams explain the neutral, clutch, and sidestand interlocks. Separate ignition, charging, and FI circuit diagrams support electrical testing alongside fuse ratings and component-specific resistance specifications. Listed equipment includes the YM-03170 rear drive belt tension gauge and YM-03176 fuel pressure adapter.

A Preview of Oil-Capacity and Sensor-Test Data

The engine-oil specifications distinguish the 5.00 L total capacity from service quantities: 3.70 L without oil-filter cartridge replacement and 4.10 L with replacement. The oil-change section also documents the filling and level-check conditions for the dry-sump system.

For electrical diagnosis, the engine temperature sensor specification is 0.898–1.098 kΩ at 100 °C (212 °F). The associated component-check section includes the temperature-controlled resistance test.
