Moto Guzzi California EV / Special / Sport / Jackal / Stone 2001–2013 Manual Set (P/N 03 92 01 01)

The workshop procedures, owner’s instructions, and exploded parts views support different stages of maintenance and repair. The build-specific axle, engine, and gearbox references help match procedures and components to the motorcycle before disassembly.

Coverage is limited to these early California versions and the included 2001–2002 catalogs, not the complete California range through 2013. The Special/Special Sport and Stone owner’s manuals and later parts catalogs identify hydraulic-tappet configurations; the April 2002 workshop manual does not contain a hydraulic-tappet overhaul chapter.

California EV motorcycles built from 1997–2000 through chassis KD115749 use the larger P08 injection/ignition ECU. Service work on that system is referred to separate workshop publication 29 92 01 60, which is not included. The IAW 15M diagnostic chapter should not be substituted for that publication.

PDF Text Search, Diagrams and Navigation

Search and circuit detail: Body text and parts entries support PDF text search, but some diagram labels and picture pages are not searchable. Embedded bookmarks are present in the workshop manual and five parts files; the owner’s manuals and one Stone/Stone Metal catalog copy have none. Small wiring labels require zooming, with coarser lettering on the Special/Special Sport and Stone owner’s wiring sheets.

The workshop manual is in English, German, and Dutch. The owner’s manuals and full-format parts catalogs contain Italian, English, French, and German; compact catalogs GU011 and GU012 use French item descriptions with part numbers and exploded views.

The ZIP contains 10 printable PDFs totaling 1,681 pages, including introductory material, indexes, section dividers, and blank pages. The Stone/Stone Metal catalog is supplied twice, with one additional section-marker page in the longer copy; the archive contains 1,539 non-duplicate pages.

Engine Repair, Chassis Service and IAW 15M Diagnosis

The following selected contents show the main repair and reference material. Further topics include exhaust-system removal and chassis-dimension drawings.

• Engine repair: Step-by-step engine/gearbox removal, cylinder-head and timing service, cylinder and piston inspection, clutch repair, and crankshaft and connecting-rod checks.

• Gearbox and final drive: Gearbox disassembly, shaft and selector shimming, bench reassembly, final-drive bearing service, pinion setup, and gear-contact inspection.

• Wheels and suspension: Both front-axle arrangements, wheel overhaul and spoke adjustment, adjustable and non-adjustable Marzocchi fork repair, swingarm service, and shock replacement.

• Brake systems: Separate coverage for linked EV/Special/Special Sport brakes and independent Jackal/Stone circuits, including calipers, master cylinders, discs, pads, fluid replacement, and bleeding.

• Injection and ignition: IAW 15M sensor and actuator diagnosis, ECU error reset, throttle-position adjustment, cylinder synchronization, idle checks, and CO setup.

• Electrical and service references: Model-specific wiring diagrams, charging-system tests, starter and instrument service, maintenance schedules, factory tool references, torque tables, and fluid specifications.

The workshop material is written for trained technicians with acquired engine-service knowledge and the specified special tools; the owner’s manuals cover rider operation and routine care.

Engine and Driveline Overhaul

Internal engine coverage includes lubrication-pressure checks, oil-pump inspection, valve and guide measurements, cylinder/piston selection drawings, and connecting-rod weight and crankshaft-balancing references. Gearbox sections distinguish engagement-gear builds and provide primary-shaft, secondary-shaft, and selector-drum shimming information.

Factory equipment references include gearbox support 14 92 96 00 and cam/ignition degree wheel 19 92 96 00. Clutch work identifies flywheel/starter-ring lock 12 91 18 01 and clutch assembly tool 30 90 65 10; gearbox work specifies secondary-shaft lock 12 90 71 00.

The rear-drive chapter goes beyond removal and installation, with bearing and seal inspection, pinion/crown matching, adjustment shims, and illustrated gear-tooth contact patterns.

Axle, Wheel and Suspension Differences

Front-wheel procedures distinguish an axle retained by an external nut from one threaded into the left fork leg. Wheel material also separates BBS tubeless spoked rims, the later EV tubeless arrangement, and steel-rim configurations.

Fork coverage includes internal disassembly and reassembly, seals, guide bushings, damping assemblies, and a troubles/causes/solutions chart. Rear suspension sections address swingarm bearings, shock removal, and the model-specific adjustment arrangements.

For Special 2nd series, Special Sport, Jackal, and Stone wheels with inner tubes, the spoke-adjustment warning explains how working with the tire installed can damage nipple covers and puncture the tube. This warning does not apply indiscriminately to the EV tubeless-wheel procedures.

Linked and Separate Brake Circuits

On EV, Special, and Special Sport, the rear pedal operates the rear and left-front calipers while the right-front caliper remains on the hand lever. Jackal and Stone have independent front and rear circuits, with their own fluid-service and bleeding sections.

The linked-brake power limiter is matched to rear-suspension characteristics. The manual warns that replacement shocks with different specifications can compromise brake-pressure distribution.

Secure the motorcycle properly and isolate the electrical system where required before fuel, brake, or major chassis work.

Injection Diagnostics and Electrical References

The IAW 15M chapter distinguishes current from stored faults and describes tests for sensor circuits, injectors, coils, the fuel-pump relay, and ECU functions. Its circuit checks help separate wiring or component faults from control-unit faults.

ECU reset and CO-trim procedures use the Motorbike Diagnostic Software Tool, code 00 97 97 15, with the appropriate interface. Software and interface hardware are not included in this PDF archive. The injection chapter also documents USA/SGP/CAN fuel-vapor purification and recirculation equipment.

Electrical references include the EV 2001/Stone/Special Sport wiring diagram, the separate EV 1997–2000 diagram, California Special and Jackal diagrams, IAW 15M connector and circuit keys, and an alternator current-intensity chart. Standard and USA/SGP/CAN battery procedures are distinguished, alongside fuse-board, side-stand-switch, lighting, dashboard, and handlebar-control service.

The parts catalogs provide exploded assemblies and numbered component lists. Their standard- and hydraulic-tappet component illustrations support parts identification; they do not replace the corresponding repair procedures. No separate Jackal parts catalog is included.

Sample Valve-Clearance and Alternator Test Data

For the mechanical-tappet engines addressed by the workshop procedure, the valve-clearance examples are 0.10 mm intake and 0.15 mm exhaust, measured cold with the piston at compression TDC and both valves closed.

The alternator checks specify winding continuity of 0.2–0.3 Ω between the generator leads and insulation to ground above 10 MΩ. Both resistance checks apply with the engine switched off and the generator isolated from the rest of the electrical system.
