Spark Plug Inspection Or Replacement:
Refer to manual for specific mileage, typically around 12,000-24,000 km (7,500-15,000 miles).
Chain Lubrication And Adjustment:
Regularly, as per manual, typically every 1,000 km (600 miles) or after riding in wet conditions.
Coolant Flush And Replace:
Refer to manual, typically every 2 years or 24,000 km (15,000 miles).
Brake Fluid:
DOT 4 recommended.
Coolant:
High-quality ethylene glycol-based coolant with demineralized water (50/50 mix).
Typical Concerns:
While generally reliable, potential issues can include clutch wear with hard use, regulator/rectifier failures (common in many bikes of this era), and occasional minor electrical gremlins if not maintained. Suspension components may require servicing over time.
Maintenance Importance:
Adhering to the service intervals and using correct fluids and parts is crucial for longevity and performance.
