The recommended oil type for the Yamaha TT-R50EM TT-R50E 2021 is SAE 10W-40, specifically designed for 4-stroke engines.
The air filter should be checked and cleaned every 600 miles or 1,000 kilometers. If it is damaged or excessively dirty, it should be replaced.
The recommended tire pressure for the front tire is 15 psi and for the rear tire is 15 psi.
If the Yamaha TT-R50E won't start, check the fuel level, ensure the kill switch is in the 'On' position, inspect the spark plug for wear or damage, and check the battery charge.
After riding in wet conditions, clean and lubricate the chain, check the brakes for proper function, and inspect the bike for any water accumulation or corrosion.
To adjust the chain tension, loosen the rear axle nut, adjust the chain tensioners equally on both sides, and ensure there is 1.2-1.6 inches of slack in the chain. Tighten the axle nut after adjustment.
The Yamaha TT-R50EM TT-R50E 2021 should be fueled with regular unleaded gasoline with a minimum octane rating of 87.
To increase battery longevity, keep the terminals clean, avoid leaving electrical components on when the engine is off, and use a trickle charger when the bike is not in use for extended periods.
For off-season storage, fill the fuel tank and add a fuel stabilizer, clean the bike thoroughly, lubricate moving parts, disconnect the battery, and store it in a dry, temperature-controlled environment.
Signs that the Yamaha TT-R50E may need a valve clearance check include difficulty starting, reduced power, unusual noises from the engine, and poor fuel efficiency.
