The recommended engine oil for the Yamaha YFM125GB Grizzly 125 2012 is Yamalube 4, 10W-40 or any equivalent high-quality 4-stroke motor oil.
It is advised to change the oil every 6 months or every 1,000 miles, whichever comes first, to ensure optimal performance and longevity of your ATV.
The recommended tire pressure for the Yamaha Grizzly 125 is 4 psi for the front tires and 4 psi for the rear tires.
If your Grizzly 125 won't start, check the battery charge, ensure the fuel valve is open, inspect the spark plug, and verify that the kill switch is in the 'Run' position.
Perform regular checks on the oil level, brakes, and tire pressure every month. Change the oil and filter every 6 months, and inspect the air filter, spark plug, and brake pads every 1,000 miles.
To adjust the chain tension, loosen the rear axle nut, adjust the chain tensioner bolts evenly on both sides until the chain has 20-30 mm of slack, then retighten the axle nut.
If the ATV overheats, stop the engine immediately, let it cool down, check the coolant level, and inspect for any radiator blockages or leaks.
To improve fuel efficiency, regularly maintain the engine, keep the tires properly inflated, use the recommended oil, and avoid excessive idling.
Use a high-quality ethylene glycol-based antifreeze coolant mixed with distilled water in a 1:1 ratio.
To replace the air filter, remove the seat, open the airbox cover, take out the old filter, and install a new air filter ensuring it is seated properly before closing the airbox.
