Maintenance checklist

Air filter — clean or replaceevery ride

Do this basically every ride. A clogged filter chokes power; a torn one lets grit into the engine.

Air filter
Engine oil & oil filter~every 10h

Fresh oil protects the whole motor. Hard riders change it often — many every few hours of race time.

Oil filter
Top-end / piston check~every 80h

The piston and rings wear out. Replacing on time prevents a far more expensive bottom-end failure. (2-strokes need it much sooner than 4-strokes — check your manual.)

Top-end kit
Valve clearance check~every 25h

Four-stroke valves tighten over time and can burn if ignored. Checking is cheap; a new head isn’t.

Feeler gauge
Spark plug~every 30h

A fresh plug means easy starts and clean running. Cheap insurance.

Spark plug
Chain & sprockets~every 40h

A worn chain and sprockets rob power and can snap. Replace as a set.

Chain & sprocket kit
Coolant~every 50h

Fresh coolant stops overheating and corrosion. Roughly once a season for most riders.

Coolant
Grease linkage & bearings~every 20h

Re-greasing the suspension linkage and wheel bearings keeps the bike handling right and saves bearings.

Grease

Guideline intervals only — they vary by year and how hard the bike is ridden. Always confirm exact figures in your owner's manual.
