Yamaha Stratoliner S XV19SX(C), Stratoliner XV19MX(C), Stratoliner Midnight XV19CTSX(C) / XV19CTMX(C), Roadliner S XV19CSX(C), Raider XV19CX(C) 2008 Service Manual (P/N LIT-11616-21–26)

Yamaha's first-edition service manual (June 2007), P/N LIT-11616-21-26, covers the 2008 XV19SX(C), XV19MX(C), XV19CTSX(C), XV19CTMX(C), XV19CSX(C) and XV19CX(C) models. The original cover also carries 1D7-28197-12.

Searchable PDF and Color Wiring Sheets

Search and diagram detail: Searchable text and embedded bookmarks provide access to service chapters, component sections and wiring sheets. Small component identifiers, connector labels and wire codes on the color wiring diagrams need zooming.

One printable, English-language, 494-page PDF, including the original front matter and covers, six blank pages, and both color wiring sheets.

Engine Overhaul, FI Diagnosis and Chassis Service

These selected service topics outline the manual's coverage rather than reproduce its full contents. Other subjects include windshield and backrest removal and installation.

• Engine and valve train: Engine removal, internal inspection, crankcase separation, gear-driven camshaft installation, valve-clearance adjustment and hydraulic valve lifter bleeding.

• Clutch and driveline: Clutch plate and hydraulic-control service, transmission inspection, shift-mechanism assembly, and transfer gear case and oil-pump checks.

• Fuel and exhaust controls: Throttle-body synchronization, pressure-regulator testing, throttle position sensor adjustment, ISC (idle speed control) system checks and EXUP cable adjustment.

• Brakes and chassis: Dual front-disc and rear-disc brake service, hydraulic bleeding, front fork rebuilding, steering-head service, swingarm inspection and drive-belt replacement.

• Electrical diagnosis: Ignition, starter, charging and fuel-pump troubleshooting, with sensor checks, ECU fault-code charts and actuator tests.

• Service references: Periodic maintenance charts, tightening torques, fluid capacities, wear limits, lubrication charts, cable-routing layouts and model-specific color wiring diagrams.

Written primarily for Yamaha dealers and qualified mechanics, this manual assumes a basic understanding of motorcycle mechanics and repair techniques.

Valve Train and Internal Engine Repair

Hydraulic valve lifters normally compensate valve clearance automatically; the manual explains when manual adjustment is needed. Its lifter-bleeding procedure covers new lifters and lifters that leak oil, including kerosene preparation and position-specific checks.

Camshaft installation notes address gear alignment and the risk of damaging gear teeth while locking the drive and driven gears.

The dry-sump engine oil lubrication chart and routing diagrams accompany oil-pump, relief-valve and strainer inspections. Cylinder, piston-ring, crankshaft and connecting-rod sections provide measurement methods and wear specifications for internal repair.

Clutch Hydraulics and Transfer Gear Case

Wet multi-disc clutch coverage extends to the master and release cylinders, with exploded views, inspection criteria and reassembly details. The transmission section includes main-axle and drive-axle assembly; transfer gear case coverage addresses the middle drive, oil pipes and its oil pump.

Fuel-System Testing and Variant Differences

Pressure-regulator testing identifies the required pressure gauge and fuel-pressure adapter, including Yamaha tool references YU-03153 and YM-03176. Separate California canister checks address the evaporative-emission hoses for the two model groups.

Cable-routing layouts distinguish XV19S/M/CTS/CTM configurations from XV19CS/C configurations. Fork, steering-head and exhaust sections retain their model-specific procedures and specifications.

ECU Fault Tracing and Circuit Diagrams

Using the circuit diagrams and sensor test specifications beside the vehicle supports electrical fault tracing. The ignition circuit diagram, starting circuit cut-off operation chart, self-diagnostic function table and actuator operation table connect symptoms with checks of the relevant circuits and components.

Multi-function meter unit coverage includes instrument functions and ECU communication faults.

For example, EXUP fault code 17 concerns an open or short circuit, while code 18 identifies a stuck servo motor. That distinction helps separate circuit diagnosis from valve, pulley and cable checks. The servo-motor test also warns of damage from prolonged battery power.

Suspension Work and Safe Service Limits

Step-by-step instructions cover front fork disassembly and reassembly, with bushing and seal replacement details. Brake sections address caliper and master-cylinder inspection and assembly.

Rear suspension coverage includes shock assembly removal, inspection and preload adjustment; the nitrogen-charged shock must not be opened.

Brake, fuel-system and lifting work requires the manual's safety precautions, appropriate tools and secure vehicle support.

A Preview of Idle and Stator Test Data

The idling-condition table specifies 850–950 r/min and an intake vacuum of 31.3–35.3 kPa, with oil temperature listed at 80–90 °C. These entries accompany the throttle-body synchronization material.

For charging-system diagnosis, the stator coil resistance specification is 0.112–0.168 Ω; the electrical section includes the corresponding coupler and test-probe views.
