Step By Step Instructions:
Provided for all service and repair jobs
Oil Change Interval:
Refer to manual for transmission oil, engine oil (pre-mix ratio, not separate sump).
Air Filter Cleaning:
Frequent cleaning recommended based on riding conditions (e.g., every 5-10 hours).
Spark Plug Inspection:
Every 10-20 hours or as needed based on performance.
Brake Fluid Type:
DOT 4 recommended (refer to manual for exact specification).
Coolant Type:
Ethylene glycol based antifreeze mixture (50/50) (if liquid-cooled).
Typical Wear Items:
Piston rings, spark plugs, air filter, clutch plates, wheel bearings, suspension seals, chain, sprockets.
Carburetor Tuning:
May require periodic adjustment or cleaning due to its 2-stroke nature and off-road use.
Power Valve Maintenance:
Service and cleaning of the exhaust power valve mechanism is critical for optimal performance.
