The recommended oil type for the Yamaha YFM50RX Raptor 2008 is SAE 10W-40, specifically formulated for wet clutch systems.
It is recommended to clean the air filter every 30 hours of operation or more frequently if used in dusty conditions.
The recommended tire pressure for the front tires is 4 psi and for the rear tires is 4 psi.
Check the battery connections and charge, ensure the fuel valve is on, inspect the spark plug, and verify the kill switch is in the correct position.
Clean the ATV thoroughly, change the oil, stabilize the fuel, disconnect the battery, and store it in a dry, cool place.
Loosen the rear axle nut, adjust the chain tension using the adjuster bolts until the chain has about 0.6-1.0 inches of slack, then retighten the axle nut.
Stop the ATV immediately, allow the engine to cool, check for coolant leaks and coolant level, and inspect the radiator for blockages.
Replace the spark plug every 6 months or 100 hours of operation, whichever comes first, to ensure optimal performance.
Common signs include difficulty shifting, slippage under load, and unusual noises during operation.
Regular maintenance, upgrading the exhaust system, using performance air filters, and proper tire selection can help improve performance.
