The recommended engine oil for the Yamaha Grizzly 350 is Yamalube 4, 10W-40 or an equivalent high-quality, 4-stroke engine oil.
It is recommended to change the oil and oil filter every 20 hours of operation or every 6 months, whichever comes first.
To adjust the valves, remove the front fender and fuel tank to access the valve cover. Use a feeler gauge to measure and adjust the clearance on a cold engine to the specifications outlined in the service manual.
Use a high-quality ethylene glycol antifreeze containing corrosion inhibitors designed for aluminum engines, mixed with distilled water at a 1:1 ratio.
Check the battery charge and connections, inspect the spark plug, ensure the fuel system is not clogged, and verify the operation of the starter relay and switch.
Routinely check brake pads for wear, inspect brake lines for leaks, and ensure brake fluid levels are correct. Replace worn pads and bleed the brakes to remove air from the system.
The recommended tire pressure for both front and rear tires is 4.4 psi (30 kPa), but always refer to the specific tire manufacturer’s guidelines.
Remove the air filter cover, take out the filter, and wash it with a mild detergent and water. Dry it thoroughly before applying air filter oil and reinstalling. Inspect for any damage and replace if necessary.
Stop the engine immediately if the ATV overheats. Check the coolant level, inspect the radiator for obstructions, and ensure the cooling fan is operational. Allow the engine to cool before continuing operation.
To adjust the drive chain, loosen the rear axle nut and adjust the chain tensioner to achieve proper slack. Ensure the chain is not too tight or loose, then retighten the axle nut securely.
