Wear Limits:
Specifications for component wear limits (e.g., piston ring gap, brake pad thickness, belt wear) to guide replacement decisions and ensure optimal performance and longevity.
Service Intervals:
The manual details specific intervals for engine oil changes, spark plug checks/replacement, air filter cleaning/replacement, transmission oil changes, brake system checks, and general inspections. Typical intervals for 50cc scooters include oil changes every 1,000-2,000 km and spark plug replacement every 5,000-10,000 km. Detailed charts are provided within the manual.
Engine Oil Type:
The manual specifies the correct viscosity and API service classification for the 2-stroke engine oil. Typically, it would be a JASO FD certified 2-stroke oil.
Transmission Oil Type:
The manual specifies the correct viscosity and type of gear oil for the CVT transmission. Usually, a lightweight gear oil (e.g., SAE 80W-90) or specific scooter transmission fluid is recommended.
Brake Fluid Type:
The manual specifies the DOT classification for the brake fluid, typically DOT 3 or DOT 4 for hydraulic brake systems.
Common Issues:
While not explicitly listed as 'common issues' in the product description, the manual would cover troubleshooting for typical 2-stroke scooter problems such as carburetor tuning, ignition system issues, variator/belt wear, and exhaust system maintenance.
Common Wear Items:
The manual would likely detail the inspection and replacement intervals for common wear items such as the drive belt, clutch shoes, brake pads, and tires, based on typical usage for a 50cc scooter.
