The Yamaha YFM25RSEY Raptor 250 2009 is designed to run on unleaded gasoline with a minimum octane rating of 87.
It is recommended to change the engine oil every 20 hours of riding or every 6 months, whichever comes first.
The recommended tire pressure is 4.2 psi for the front tires and 4.2 psi for the rear tires. Always check the pressure when the tires are cold.
If the Raptor 250 won't start, check the battery connections, ensure the fuel valve is on, and inspect the spark plug for wear or fouling.
To adjust the chain tension, loosen the axle nut, adjust the chain adjuster bolts equally on both sides, and tighten the axle nut back to the specified torque.
Improving performance can be achieved by upgrading the exhaust system, installing a high-performance air filter, and properly tuning the carburetor.
If overheating occurs, stop the engine and let it cool down. Check the coolant level and inspect the radiator for obstructions or dirt.
Regularly inspect brake pads for wear, check brake fluid levels, and inspect brake lines for any leaks or damage. Replace parts as needed.
Before storing, clean the ATV thoroughly, add fuel stabilizer, change the oil, and disconnect the battery. Store in a cool, dry place.
To replace the air filter, remove the seat, open the airbox cover, take out the old filter, and install a new one ensuring it is seated properly.
