Engine Oil Change:
Every 4,000 km (2,500 miles) or 6 months, whichever comes first. Inspect oil level more frequently.
Oil Filter Replacement:
Replace at every oil change (or every 8,000 km / 5,000 miles).
Spark Plug Service:
Inspect and clean/gap every 4,000 km (2,500 miles). Replace as needed.
Air Filter Cleaning:
Clean every 4,000 km (2,500 miles). Replace as needed, especially if operating in dusty conditions.
Chain Maintenance:
Lubricate and adjust chain every 1,000 km (600 miles) or after riding in wet conditions.
Engine Oil:
Yamalube 4 (or equivalent) SAE 10W-40 API SG or higher. API classification SJ or SL recommended for improved engine durability.

1.80 liters (1.9 US qt) without filter change; 2.00 liters (2.1 US qt) with filter change.
Brake Fluid:
DOT 3 or DOT 4 brake fluid.
Fork Oil:
Genuine Yamaha Fork Oil G-10 or equivalent SAE 10W fork oil.
Coolant Type:
N/A (Air-cooled engine)
Common Wear Items:
Clutch plates, brake pads, fork seals, and chain/sprockets are common wear items subject to regular inspection and replacement based on usage.
Carburetor Issues:
Carburetor can become clogged with infrequent use or poor fuel quality, leading to starting and running issues. Regular cleaning and proper fuel storage are recommended.
Electrical Connections:
Corrosion can occur on electrical connectors, particularly in humid or salty environments, leading to intermittent electrical faults. Inspection and dielectric grease application are beneficial.
