Searchable Service Text and Wiring Detail

Search, bookmarks, and diagram labels: Service text is searchable, with embedded bookmarks for chapters and individual procedures. Labels inside the main wiring diagrams are not text-searchable. Small wire-color codes and connector markings require zooming.

One printable, 410-page English PDF, including the cover and front matter, 11 blank pages, and the final model-application page.

Engine, CVT, and Chassis Service

The following selected service topics show the range of work covered. Other sections include clean-air-system inspection and fuel-level-sensor testing.

• Engine repair: Engine removal and installation, cylinder-head and piston service, camshaft installation, crankcase disassembly, and internal wear inspection.

• Fuel system: Keihin CVK32 carburetor removal, disassembly, cleaning, inspection, reassembly, and float-height adjustment, plus throttle and choke cable service.

• Converter system: CVT drive-belt replacement, pulley inspection, centrifugal-clutch disassembly and assembly, and component-specific wear limits.

• Transmission and final drive: Transmission-case disassembly, shift-mechanism inspection, propeller-shaft and rear-axle service, and bevel-gear backlash and tooth-contact adjustment.

• Brake service: Master-cylinder and caliper disassembly, hydraulic-line bleeding, rear proportioning-valve inspection, pad replacement, and parking-brake adjustment.

• Steering and suspension: Wheel alignment, front-hub bearing replacement, steering-shaft and tie-rod inspection, shock-preload adjustment, and suspension-arm and swingarm service.

• Electrical diagnosis: Alternator and regulator/rectifier tests, ignition-coil and crankshaft-sensor checks, starter-relay testing, and wiring diagrams.

Written primarily for trained mechanics in properly equipped shops, the manual also supports basic owner maintenance and repair where mechanical knowledge, proper tools, and workshop procedures are understood.

Engine Inspection and Carburetor Repair

Step-by-step instructions cover valve-clearance adjustment and Keihin CVK32 carburetor rebuilding. Carburetor inspection extends to the jets, float-valve needle, vacuum piston, and diaphragm; fuel-tank, fuel-tap, and air-cleaner procedures cover the supporting components.

Engine diagnosis includes a compression-test interpretation table, valve-to-guide measurements, piston-ring checks, and crankshaft inspection limits. The Engine Oil Flow Chart shows the lubrication paths alongside oil-pump and oil-screen service information.

The non-return camshaft chain tensioner has a specific caution: partially loosening and then retightening its mounting bolts can damage the tensioner and timing chain.

Radiator and Water-Pump Service

Cooling-system coverage includes pressure testing, radiator removal, thermostat testing, and water-pump mechanical-seal replacement. The pump instructions identify the impeller’s left-hand threads.

CVT Tools and Bevel-Gear Setup

Clutch work specifies the Clutch Spring Compressor 57001-Y006 and Flywheel & Pulley Holder 57001-1605. The instructions warn that working without the specified compressor can damage the clutch spring.

Transmission gear ratios accompany the internal service information. Output-drive and rear final-drive sections provide separate backlash checks, tooth-contact patterns, and shim tables, supporting gear setup after related bearings or gears are replaced.

Recoil-starter procedures apply to non-European versions; European models use electric starting.

Brake Circuits and Chassis Adjustments

The brake chapter distinguishes the front master cylinder from the rear lever-operated and pedal-operated master cylinders. Separate bleeding procedures address the rear caliper and proportioning valve, followed by checks for braking power, drag, and leakage.

Wheel-alignment instructions cover steering centering and toe-in. Caster and camber are built in and require no adjustment.

Use appropriate protective equipment and refer complex diagnostic or brake work to a qualified mechanic if you lack the experience or workshop equipment.

Electrical Fault Tracing and Routing Views

Charging-system tests distinguish insufficient alternator output from regulator/rectifier faults. Circuit diagrams and electrical test specifications give a mechanic references for tracing charging, ignition, and starting problems.

Illustrated references include the Wiring Diagram, Ignition System Circuit, Electric Starter Circuit, and Cable, Wire, and Hose Routing views for the main wiring harness.

The eighteen-chapter layout includes an appendix with troubleshooting guidance for starting problems, overheating, converter operation, and handling faults. Its symptom-and-cause lists support diagnosis without claiming to cover every possible failure.

A Preview of Valve, Spark Plug, and Radiator-Cap Specifications

Cold-engine valve-clearance specifications are 0.08–0.12 mm for both intake and exhaust valves. Spark plug service specifies a 0.8–0.9 mm gap for the NGK DPR7EA-9.

The radiator-cap inspection section lists a relief pressure of about 108 kPa (16 psi), specifically for cap testing. Component torque tables also cover fasteners such as the engine oil drain plug and final gear-case filler cap.
