To perform an oil change, first warm up the engine, then turn it off. Place an oil pan beneath the engine, remove the drain plug, and let the oil drain. Replace the drain plug, remove the oil filter, and install a new filter. Refill with the recommended oil type and amount. Finally, check the oil level with the dipstick.
If the Grizzly 350 won't start, check the battery for charge and connections. Ensure the fuel valve is on and there's fuel in the tank. Inspect the spark plug for wear or fouling and replace if necessary. Verify that the kill switch is in the 'run' position. If issues persist, consult a professional.
The air filter should be checked every 20 hours of operation or once a month, and cleaned or replaced as necessary. More frequent maintenance may be needed in dusty environments to ensure optimal performance.
The recommended spark plug for the 2009 Yamaha Grizzly 350 is the NGK DR8EA. Ensure it is gapped correctly according to the manufacturer's specifications before installation.
To improve fuel efficiency, regularly maintain your ATV by keeping the air filter clean, ensuring tires are properly inflated, and using the recommended engine oil. Avoid carrying excessive weight and maintain a steady throttle during rides.
The recommended tire pressure for the Yamaha Grizzly 350 is typically 4 psi for the front tires and 5 psi for the rear tires. Always check the owner's manual for the exact specifications and adjust according to load and terrain.
To adjust the brakes, locate the adjuster nuts near the brake levers. Turn the adjuster nuts to achieve the desired brake lever free play. Ensure both front and rear brakes are balanced and test the brakes in a safe environment after adjustment.
To clean the carburetor, remove it from the ATV, disassemble it, and use a carburetor cleaner to clean all parts thoroughly. Pay special attention to jets and passages. Reassemble the carburetor, install it back on the ATV, and adjust the idle and air-fuel mixture as needed.
To replace the drive belt, remove the belt cover, loosen the tensioner, and slide the old belt off. Install the new belt, ensuring it is aligned correctly, and retighten the tensioner. Replace the belt cover and check for proper operation.
Before storing the Grizzly 350, clean it thoroughly, change the oil, and fill the fuel tank with stabilized fuel. Remove the battery and store it in a cool, dry place. Elevate the ATV to prevent tire damage, and cover it to protect against dust and moisture.
