2007 Buell Ulysses XB12X, XB12 Factory Service Manual (P/N 99494-07Y)

This 2007 Buell Ulysses Service Manual, P/N 99494-07Y, is specific to the Ulysses XB12X and its 1203cc, air-cooled 45-degree V-twin. The manual comprises 647 PDF pages across 30 files, covering scheduled maintenance through internal engine and transmission repair. Its crankcase-splitting procedures, precision inspection work, fuel-pressure testing, and Digital Technician requirements make it best suited to professional technicians or experienced owners who are mechanically qualified and properly equipped.

XB12X Service and Repair Coverage

• Maintenance and adjustment: Covers the factory service schedule, engine and transmission lubrication, brake bleeding and pad replacement, clutch and primary-chain adjustment, suspension setup, steering-head inspection, static ignition timing, headlight alignment, and TPS zeroing.
• Chassis repair: Details wheel and bearing service, brake master-cylinder and caliper disassembly, front-fork teardown and seal replacement, steering-head bearing replacement, swingarm and isolator work, rear-shock removal, frame service, and exhaust and body-component procedures.
• Engine overhaul: Walks through compression and leakdown testing, engine rotation and removal, cylinder-head and rocker-box repair, valve-guide and seat work, cylinder and piston inspection, ring and wrist-pin bushing service, oil-pump and hydraulic-lifter repair, cam-gear work, and crankcase, flywheel, and bearing service.
• Dynamic Digital Fuel Injection (DDFI/DDFII): Provides check-engine-lamp code retrieval, Digital Technician and breakout-box testing, wiggle tests, no-start and misfire charts, fuel-pressure diagnosis, and fault isolation for the ECM, injectors, ignition coil, sensors, cooling fan, fuel pump, throttle body, and intake system.
• Drive, transmission, and starter: Includes wet multi-disc clutch and primary-drive repair, drive-belt and idler-pulley service, internal five-speed transmission disassembly and assembly, mainshaft and countershaft work, shifter mechanisms, starter-circuit diagnosis, current-draw tests, and starter and solenoid repair.
• Electrical systems and shop reference: Documents the starter interlock, charging system, alternator, voltage regulator, battery, lighting, instruments, speedometer testing, switches, fuses, main harness, interactive-exhaust wiring, auxiliary outlets, connector repair, and hose and wire routing.

Model-Specific Systems

Coverage is for the 2007 Ulysses XB12X, not the entire 2007 XB range. The main fuel section explains the open- and closed-loop Buell Dynamic Digital Fuel Injection system, its returnless fuel supply, ram-air induction, and ECM-controlled interactive muffler. A California-model section covers the evaporative-emissions canister and hose routing, while the Japan-only appendix adds active-intake Code 22 diagnosis, cable adjustment, setting verification, and solenoid removal and installation.

Wiring, Routing, Tooling, and Specifications

The wiring appendix provides separate Main Harness, Engine Management Circuit, and Lighting Circuit sheets, along with Horn and Instruments, Starting, and Charging circuit diagrams. Connector coverage goes beyond pin locations: it includes Amp Multilock, Deutsch, and Packard terminal removal, installation, and crimp inspection. A separate routing appendix maps the brake lines, emissions plumbing, main harness, oil lines, and clutch, throttle, and interactive-exhaust cables.

Special tools are identified where they apply and in a dedicated appendix. Examples include the HD-44750 Digital Technician, HD-42682 Breakout Box, B-45522 fuel-pressure gauge adapter, B-43987 engine cradle, HD-45966 front-fork compressor, and HD-46285 transmission assembly fixture. Component-specific torque tables, fluid capacities, pressure-test data, inspection and wear limits, clearances, electrical test values, and adjustment specifications are provided throughout.

Transmission Scope and Repair Cautions

Internal transmission repair is not an in-frame shortcut: the manual specifies engine removal and crankcase splitting before the gearbox can be removed. It also warns that retightening the cylinder-head bolts can damage the engine, and that resting a removed engine on its primary side can damage the clutch-cable end fitting.

Brake, pressurized fuel-system, battery, and engine-removal work should be performed with the motorcycle securely supported and the manual's fuel, electrical-isolation, lifting, and fire-safety precautions followed.
