VEHICLE/EQUIPMENT INTRODUCTION

The 2009 Harley-Davidson VRSC (V-Rod) represents perhaps the most radical engineering departure in Harley-Davidsons entire product history. Co-developed with Porsche Engineering, the Revolution engine at its core replaces the archetypal air-cooled pushrod V-twin with a 60-degree, dual-overhead-cam, liquid-cooled, fuel-injected V-twin that produces outputs and RPM ranges that would have been unthinkable from a traditional Harley powerplant a decade earlier. The 1,130cc Revolution engine in the 2009 VRSC produces approximately 115 hp in standard V-Rod trim, with the VRSCDX Night Rod Special and VRSCSE CVO variants receiving incremental power and equipment upgrades. The engine is managed by a Delphi engine control module with closed-loop fuel injection using lambda sensor feedback, electronic throttle control, and altitude/temperature compensation -- a level of sophistication that places the VRSC closer to a Japanese sportbike than a conventional Harley.

The engine architecture uses a cast-aluminum structure that serves as a stressed member of the frame. The swingarm mounts directly to the rear of the engine crankcase, eliminating the need for a separate frame cradle in the rear triangle. This design contributes to the VRSCs distinctive low center of gravity, short overall height, and long-wheelbase stance. The dual overhead cams per bank are driven by silent chains from the crankshaft, operating four valves per cylinder through hydraulic lash adjusters (no manual valve adjustment required -- lash is self-adjusting). A single overhead camshaft per bank actuates the intake and exhaust valves through roller finger followers. The fuel injection system uses a single large-bore throttle body (approximately 50mm) with electronic throttle valve control, positioned between the V of the cylinders in a mid-mount location for optimal intake tract length.

By 2009, the VRSC platform was well-matured. Early production issues with the Revolution engine -- including oil pump drive gear failures, cam chain tensioner concerns, and oil cooler leak points -- had been addressed through running changes. The 2009 model year continued to build on this reliability with refined PCM calibration, improved wiring harness routing, and updated cooling system components. The VRSC is not a traditional Harley -- it demands a different approach to maintenance and diagnostics. This manual provides the complete factory procedures necessary to service this unique machine properly.

SERVICE & REPAIR SCOPE


Engine Removal and Installation - The Revolution engine is a stressed frame member, so removal requires a specific sequence: frame rear section disconnection, swing arm pivot removal, exhaust header bolt removal from both banks, coolant system drain and hose disconnection (radiator and oil cooler lines), fuel system quick-disconnect depressurization (critical: relieve fuel rail pressure before disconnecting), wiring harness bulkhead connector separation, and primary chaincase disconnection. Motor mount bolt torque specification is critical during reinstallation for proper frame geometry.
Cylinder Head Service - DOHC cylinder head bolt removal sequence for left and right bank (cam removal required to access head bolts). Camshaft removal procedure with cam chain sprocket identification (timing marks must be noted before removal). Cam chain tensioner shoe inspection for wear and replacement. Hydraulic lash adjuster testing using leak-down procedure (pressurized bleed test). Intake and exhaust valve spring pressure specifications. Valve stem oil seal replacement. Combustion chamber carbon deposit inspection and removal.
Engine Top-End - Cylinder removal (individual cylinder removal is possible without full engine teardown). Piston ring end-gap measurement with ring squared in cylinder bore. Piston skirt clearance measurement. Wrist pin removal (press-fit design, requires arbor press). Cylinder bore inspection for Nikasil coating wear and scoring (Nikasil is a nickel-silicon carbide electroplating -- damaged coating requires cylinder replacement or professional replating). Head gasket inspection for coolant seepage or compression leak between the two cylinder banks.
Bottom-End Service - Crankcase split for crankshaft access. Crankshaft main bearing inspection and replacement (bearing selection based on case bore and crank journal measurement). Crankshaft thrust clearance measurement. Oil pump removal with drive gear inspection (the oil pump drive was a known concern on early Revolution engines -- check the 2009 service bulletin status). Oil pressure relief valve inspection and spring tension. Primary chain case oil level and type specification (Formula+ or equivalent).
Fuel Injection Diagnostics - Delphi ECM fault code retrieval via the Harley-Davidson Digital Technician (DST) or compatible OBD-II scanner. Throttle body removal, bore cleaning, and electronic throttle actuator function test. Fuel injector removal from fuel rail, flow bench testing, and O-ring replacement. Fuel pressure regulator at the fuel rail (specification: approximately 42 psi static). Fuel pump in-tank assembly removal and pressure specification verification. MAP sensor and IAT sensor resistance testing. Coolant temperature sensor specification check.
Primary Drive and Clutch - Primary chaincase cover removal with gasket inspection. Primary chain adjustment (free-play specification). Clutch pack disassembly: friction plate thickness measurement, clutch spring free-length inspection, clutch basket inspection for notching on engagement splines (common at higher mileage). Clutch release mechanism inspection. Primary chain tensioner shoe replacement.
Transmission and Drive Belt - Inner primary disassembly for transmission access. Transmission gear set inspection (5-speed constant mesh). Shift drum and shift fork wear assessment. Main shaft and countershaft bearing preload. Drive belt tension measurement (deflection method with specified force). Belt width wear measurement (narrowing indicates excessive wear). Belt alignment verification using the specified alignment tool. Rear belt pulley and transmission sprocket inspection.
Electrical System - Wiring harness routing diagram with connector identification. Starter motor removal and brush inspection (the Revolution starter is gear-driven from the transmission side). Voltage regulator/rectifier function test. Stator output testing (three-phase AC specification). Battery removal and BMS (Battery Management System) module diagnostics. Security system (H-D Smart Security) module service and key fob programming.
Cooling System - Coolant drain and refill procedure with bleeding through the system. Radiator removal and fin inspection. Thermostat opening temperature test (approximately 88 degrees C). Electric cooling fan function test and relay diagnosis. Oil cooler connection inspection for seepage (a known issue area). Water pump circulation impeller inspection.
Front Suspension and Brakes - 43mm inverted front fork disassembly. Fork oil replacement with specified viscosity and volume per leg. Fork seal replacement (common wear item on the relatively heavy VRSC front end). Front brake pad replacement with inspection of the monobloc four-piston caliper for piston boot integrity. Brake rotor thickness and run-out minimum specification.
