Maintenance
| Component | Interval | Details |
| Oil Filter | Not applicable | Two-stroke engines do not have a traditional oil filter. Oil is mixed with fuel or injected and consumed during operation. Ensure the oil injection system functions correctly and use the recommended 2-stroke oil. |
| Spark Plugs | Annually (start of season) | Start each season with a fresh set of spark plugs. Inspect them regularly for wear and proper gap. |
| Drive Belt | Regular inspection, replace as needed | Inspect the belt for wear, glazing, or burn spots. Replace if damage is observed. |
| Air Filter | Every 50 hours or more often | Inspect frequently, especially in dusty conditions. Replace if the element is clogged, as it is often non-cleanable. |
| Coolant | Regular check (before each ride or seasonally) | Check level when cold. Pressure test system annually and inspect coolant strength seasonally. |
| General Lubrication | Every 75 to 250 hours or 1,600 km | Lubricate all fittings, pivots, and cables. Rear suspension pivot shafts may require lubrication every 1,600 km. |
| Annual / Pre-Season Inspection | Annually (before season) | Check spark plugs, lights, steering, track tension and alignment, hyfax/sliders, battery, drive belt, and carbides. |
The maintenance intervals below are based on general guidelines and common practices. It is highly recommended to consult your model's official owner's manual for accurate and detailed information.
