🔧 Maintenance

Engine Oil Change:

Every 3,000 km (1,800 miles) or 6 months, whichever comes first. (Note: This is for the transmission oil, not the 2-stroke oil for the engine's fuel/oil mix).

Spark Plug Inspection:

Inspect every 1,000 km (600 miles); replace as needed or every 3,000 km (1,800 miles).

Air Filter Cleaning:

Clean every 2,000 km (1,200 miles); replace as needed.

Inspect and adjust as needed every 2,000 km (1,200 miles).

Variator Belt Inspection:

Inspect every 5,000 km (3,000 miles); replace as needed based on wear.

Common Wear Items:

Drive belt, brake shoes, spark plug, air filter, carburetor jets.

Potential Failures:

Oil leaks from crankshaft seals, carburetor clogging due to infrequent use or poor fuel quality, variator roller wear.

Carburetor Cleaning Frequency:

Due to the 2-stroke nature and frequent stop-start urban use, carburetor cleaning is often required more frequently than manufacturer intervals suggest, especially if left to sit.
