Horsepower And Torque:
Specific figures vary by year and regional tuning, but typically in the range of 15-25 hp. Torque figures are also model-specific. The manual will contain precise values.
Fuel Delivery:
Carburetor(s). The manual will detail specific carburetor models (e.g., Mikuni VM series), jetting, and adjustment procedures.
Safety Standards:
As a motorcycle, safety ratings are based on roadworthiness and component integrity. The manual covers safe operating procedures and maintenance of safety-critical systems like brakes and tires.
Handling And Stability:
Focus on proper suspension adjustment, tire pressure, and brake system maintenance for optimal handling and stability.
Protective Components:
Emphasis on maintaining the integrity of frame, handlebars, and footpegs. The manual will guide on inspecting and replacing worn or damaged components.
Instrumentation:
Basic instrumentation typically includes a speedometer, odometer, tachometer (on some models), and indicator lights for turn signals, high beam, and neutral.
Rider Aids:
Limited to advanced rider aids; focus is on mechanical and electrical systems. Maintenance of reliable braking and suspension is key.
Vehicle Interfacing:
No digital connectivity or advanced electronic systems beyond basic ignition and lighting controls.
Routine Maintenance Schedule:
The manual provides detailed service intervals for oil changes, spark plug checks/replacement, air filter cleaning/replacement, chain lubrication and adjustment, brake pad inspection, and coolant checks (if applicable to the specific model year). Typical intervals include checks every 1000-2000 km or 6-12 months.
Oil And Coolant:
The manual will specify recommended engine oil (e.g., 10W-40, API classification), gearbox oil, and potentially coolant type and mixture ratio if water-cooled variants exist within this generation. Also, specific grease types for lubrication points.
Common Wear And Tear:
Potential common issues addressed in the manual include carburetor tuning difficulties, clutch wear, suspension seal leaks, exhaust gasket leaks, and electrical connection corrosion, all of which are covered with diagnostic and repair procedures.
