The recommended oil type for the Yamaha YFM250XS Bear Tracker 2004 is SAE 10W-30 or 20W-40, depending on ambient temperature. Ensure it is a high-quality 4-stroke engine oil.
Check the battery for charge, inspect the spark plug for wear or fouling, and ensure the fuel is fresh. Verify that the kill switch is in the correct position and the fuel valve is open.
The front tire pressure should be set to 4.4 psi (30 kPa) and the rear tire pressure to 3.6 psi (25 kPa) for optimal performance.
The air filter should be inspected every 20 hours of operation and cleaned or replaced as necessary to ensure optimal engine performance.
First, stop the engine and let it cool down. Check the coolant level and inspect the radiator for debris. Ensure the cooling fan is operational. If the problem persists, consult a professional mechanic.
To adjust the idle speed, locate the idle adjustment screw on the carburetor and turn it clockwise to increase or counterclockwise to decrease the idle speed until it reaches the recommended RPM, typically around 1400-1500 RPM.
First, remove the spark plug cap, then use a spark plug wrench to remove the old plug. Check the gap on the new spark plug, install it, and reattach the spark plug cap securely.
Regularly inspect the chain for wear and proper tension. Clean the chain with a solvent and lubricate it with a suitable chain lubricant. Adjust the chain tension as per the manufacturer's specifications.
During routine maintenance, check the oil level, air filter, spark plug, tire pressure, brakes, and fluid levels. Inspect for loose bolts and ensure all controls operate smoothly.
Check the battery condition and connections, inspect fuses, and look for any damaged wiring or connectors. Use a multimeter to test electrical components for continuity and proper voltage.
