Troubleshooting:
Diagnostic procedures for common issues, identification of symptoms, step-by-step troubleshooting guides for engine performance, electrical faults, and mechanical problems.
Technical Specifications:
Torque specifications for fasteners, fluid capacities, recommended fluid types, engine timing, valve clearances, electrical resistance values, diagnostic trouble codes (DTCs).
Depth Of Coverage:
Comprehensive, covering everything from routine maintenance to full engine and component rebuilds. Includes detailed diagrams and exploded views.
Engine Type:
Likely a single-cylinder, four-stroke, liquid-cooled engine (typical for this class and era of Yamaha).
Engine Displacement:
660cc (as indicated by model name)
Horsepower:
Specific horsepower figures not provided in product info, but expected to be in the range of 40-50 HP for this displacement and engine type.
Torque:
Specific torque figures not provided in product info.
Fuel Delivery:
Carburetor (indicated by tags like 'Carb', 'Carburetor', 'Carb Assembly', 'Insulator'). Likely a single large-bore carburetor.
Ignition System:
CDI (Capacitor Discharge Ignition) or similar electronic ignition system.
Oil Type Specification:
Manual would specify the exact SAE viscosity grade (e.g., 10W-40) and API service classification for engine oil. Likely motorcycle-specific 4-stroke motorcycle oil.
Cooling Type:
Liquid-cooled (indicated by 'Radiator', 'Radiator Fan', 'Cooling System', 'Coolant Hose').
Oil Change Interval:
Manual will specify intervals based on mileage or time (e.g., every 3,000-5,000 km or 6-12 months).
Spark Plug Replacement Interval:
Manual will provide recommended replacement intervals or inspection points.
Chain Maintenance:
Manual will detail lubrication and adjustment intervals for the drive chain.
Coolant Type:
Manual will specify the type of coolant (e.g., ethylene glycol-based) and the correct mixture ratio with distilled water.
Brake Fluid Type:
Manual will specify the required DOT rating (e.g., DOT 4).
Common Wear Items:
Brake pads, clutch plates, fork seals, drive chain, tires, and spark plugs are common wear items that the manual will guide replacement for.
Carburetor Issues:
Carburetor synchronization, jetting, and cleaning are common maintenance items for carbureted engines.
