Fuel Type:
Unleaded Gasoline
Oil Change Interval:
Typically every 3,000-5,000 km or annually, as specified in the manual. Crucial for CVT longevity.
Air Filter Replacement:
As per manual schedule, often around 6,000-10,000 km, or when visibly dirty.
Spark Plug Replacement:
Recommended replacement intervals typically vary between 5,000-10,000 km, depending on plug type.
Belt Replacement Interval:
Crucial CVT belt replacement interval, often around 15,000-20,000 km, critical to avoid sudden failure.
Engine Oil Type:
Specific SAE viscosity grade (e.g., 10W-40 or 5W-40) and API service classification (e.g., SG, SH, SJ) will be detailed in the manual. Likely a motorcycle-specific 4-stroke oil.
Transmission Fluid:
May use the same engine oil or a dedicated gear oil, as specified in the manual.

DOT 3 or DOT 4 hydraulic brake fluid.
Common Wear Items:
CVT belt, variator rollers, clutch springs, brake pads, and suspension bushings can wear over time.
Electrical Gremlins:
As with many scooters of this era, connections in the wiring harness, particularly around the headstock and under the seat, can corrode, leading to intermittent issues. Manual troubleshooting guides are vital.
Carburetor Issues:
Carburetors can become gummed up if fuel is left stagnant for long periods, requiring cleaning and adjustment, as detailed in the manual.
