Fuel Type:
Unleaded gasoline, high octane recommended (e.g., 91-98 RON or equivalent)
Premix Ratio:
Typically 32:1 or 40:1 ratio of gasoline to 2-stroke engine oil (refer to manual for precise recommendation)
Oil Change Engine:
After every few rides or per manual recommendation (2-stroke premix system means no engine oil sump to change in the traditional sense, but gearbox oil requires periodic changes).
Gearbox Oil Change:
Every 10-20 hours of use, or annually. Check manual for specific intervals.
Air Filter Cleaning:
After every ride or every few rides, depending on conditions. Crucial for 2-stroke engine longevity.
Chain Maintenance:
Lubrication and adjustment every 5-10 hours of riding, or as needed.
Spark Plug Service:
Inspect and clean/replace as needed, typically every 20-40 hours or based on performance.
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid (verify in manual)
Coolant Type:
Ethylene glycol-based antifreeze coolant, mixed with distilled water (typically 50/50 ratio) for liquid-cooled models. Refer to manual for exact type and capacity.
Fork Oil Type:
Specific fork oil viscosity, often around SAE 5W or 10W (verify in manual).
Common Wear Items:
Piston rings, clutch plates, wheel bearings, fork seals, swingarm bushings, carburetor jets, exhaust packing.
Performance Tuning Considerations:
Carburetor jetting is critical for optimal performance and preventing engine damage due to lean conditions.
