V-Twin Overhaul, Fuel Injection, and Chassis Service

The topics below are a selection of workshop procedures. The manual also includes frame dimensions for collision checks and instructions for removing the exhaust expansion chamber.

• Maintenance and controls: Scheduled service, lubricant changes, valve-clearance checks, and throttle-cable service. The opening sections also cover VIN identification, controls, and trim removal.

• Engine repair: Step-by-step engine and gearbox removal, oil-pump service, cylinder-head and timing work, clutch repair, and alternator and flywheel removal.

• Gearbox and final drive: Bench disassembly, gear and bearing inspection, primary-shaft and selector-drum shimming, and bevel-drive setup.

• Fuel injection and ignition: Magneti Marelli IAW 15M circuit diagnosis, ECU reset, injector and coil tests, throttle-body synchronization, and idle CO adjustment.

• Brakes, wheels, and forks: Fluid replacement and bleeding for linked and separate brake circuits, caliper, disc, and pad service, wheel overhaul, spoke tension, and Marzocchi fork repair.

• Electrical service: Model-specific wiring diagrams, battery charging, starter removal and test data, lighting and dashboard service, side-stand interlock operation, and alternator and regulator checks.

Moto Guzzi addresses repair technicians and assumes familiarity with standard workshop safety practices and model-specific service tools.

Engine Inspection and Drivetrain Setup

The engine section pairs the lubrication diagram with oil-pump and pressure-regulator inspection. Cylinder-head tables cover valve-to-guide fits, valve springs, and camshaft and tappet clearances. The cylinder and piston grading tables and crankshaft balancing data are split by engine build, so you can identify the applicable specs before selecting parts.

The gearbox shaft and selector assembly drawings support bench inspection of the shafts, gears, bearings, and seals. The serial-number list identifies which early gearboxes received five-dog gears before the production change. Range-selector setup and gear-engagement checks follow reassembly. Fitting the cover with the selector drum out of neutral can cause the selector keys to foul the drum crown.

The final-drive chapter covers the Gleason crown wheel and bevel pinion, bearings and seals, shim selection, and inspection of the drive shaft and double U-joint. The tooth-contact chart helps you distinguish a pinion-depth issue from a crown-wheel position issue when checking the contact pattern.

Axle, Fork, and Brake Differences

The front-wheel chapter gives separate procedures for the nut-retained axle and the axle threaded into the left fork leg. The EV 2001, Stone, and Special Sport use the threaded-leg arrangement from first production. The adjustable Marzocchi fork drawings identify the compression and rebound cartridges, with overhaul instructions, seal and bushing checks, oil replacement, and a fault chart.

On the EV, Special, and Special Sport, the pedal operates the rear and left-front brakes through a brake-power limiter and metering valve. The hand lever operates the right-front brake independently. The Jackal and Stone have separate front and rear circuits. The manual includes limiter adjustment and a disc-brake troubleshooting chart. Wheel and powertrain removal require secure support, and brake and fuel service involve pressurized circuits.

Injection Diagnostics and Electrical Diagrams

The IAW 15M chapter separates the fuel, intake-air, and electrical circuits. Its checks cover the throttle-position potentiometer, pressure and temperature sensors, RPM/TDC sensor, coil primaries, fuel-pump relay, battery voltage, and electronic tachometer. ECU memory and mixture setup use Moto Guzzi Motorbike Diagnostic Software Tool 00 97 97 15. The software, hardware key, and software user manual are separate. The manual also warns that spark testing without the original plug caps can permanently damage the ECU.

The early EV through KD115749 has the P08 ECU. This edition shows its fuel and electrical layouts and directs injection and ignition repairs to the separate workshop manual 29920160. The fuel-vapor section illustrates the canister and rollover-valve layouts for USA, SGP, and CAN versions.

The four main wiring diagrams cover the EV 2001/Stone/Special Sport, EV 1997–2000, Special, and Jackal. Their keys identify components, connectors, wire colors, and fuse assignments.

Factory Tools and Sample Specifications

The 41-item tool catalog identifies the timing degree wheel 19 92 96 00, flywheel and starter-ring locking tool 12 91 18 01, clutch assembly tool 30 90 65 10, and selector-fork positioning tool 14 92 93 00. Section B lists 23 component-specific wet-torque entries plus standard metric fastener values. The repair chapters add wear limits, clearances, adjustment data, and electrical test values.

The final-drive chapter specifies 0.10–0.15 mm backlash with the correct pinion-to-crown-wheel tooth contact. With the engine off, the alternator test data specify 0.2–0.3 Ω across the two generator leads and more than 10 MΩ from a generator lead to ground.
