Yamaha YZ85N, YZ85LWN YZ85 2022 Owner's Manual

The recommended break-in procedure involves operating the motorcycle at varying speeds and throttle positions for the first two hours of riding. Avoid prolonged full-throttle operation and refrain from aggressive acceleration. After the break-in period, perform an oil change to remove any contaminants.
To adjust the chain tension, place the bike on a stand, loosen the axle nut, and adjust the chain adjusters on both sides of the swingarm until the chain has 30-40mm of slack. Ensure both adjusters are even to keep the wheel aligned before tightening the axle nut.
For optimal performance, use unleaded gasoline with a minimum octane rating of 91 (R+M)/2. Avoid using ethanol-blended fuels with more than 10% ethanol content.
The air filter should be cleaned and oiled after every ride in dusty conditions or every 2-3 rides in normal conditions. Always use a foam air filter cleaner and oil to ensure proper maintenance.
Signs that the clutch needs adjustment include difficulty in shifting gears, the bike creeping forward with the clutch lever fully pulled, and a lack of power transfer. Adjust the clutch cable to ensure proper free play and engagement.
To troubleshoot starting issues, first check the fuel level and ensure the fuel is fresh. Verify that the spark plug is clean and properly gapped. Inspect the fuel lines and carburetor for blockages, and ensure the kill switch is in the 'run' position.
The recommended tire pressure for the YZ85 2022 is 12 psi for both the front and rear tires. Always check the tire pressure when the tires are cold for accurate readings.
To change the transmission oil, warm up the engine, place the bike on a stand, and remove the drain bolt to let the oil drain completely. Replace the drain bolt and fill with the recommended transmission oil to the proper level, then recheck for leaks.
Before each ride, check tire pressure, chain tension, and fluid levels. After each ride, clean the bike, inspect for any damage, and lubricate the chain. Regular maintenance ensures longevity and performance.
To adjust the suspension for different terrains, modify the fork compression and rebound settings according to the terrain type. For rough terrain, soften the suspension by reducing compression damping. For smoother tracks, increase the damping for better stability.
