Pre-mix (20:1 ratio of gasoline to 2-stroke oil, specified by Yamaha)
Fuel Tank Capacity:
1.1 L (0.29 US gal)
Fuel Filter:
Inline fuel filter (typically found between tank and carburetor) should be checked and replaced as needed.
Safety Focus:
Designed with safety for young riders as a primary concern. Features include an adjustable throttle limiter and a built-in rider training system.
Throttle Limiter:
Adjustable screw to limit maximum throttle opening, controlling acceleration and top speed.
Low Seat Height:
Allows riders to easily place their feet on the ground for stability.
Easy Operation:
Automatic transmission and lack of a clutch lever reduce rider cognitive load and potential for mistakes.
Spark Plug Service:
Inspect every 1,000 km (600 miles) or annually. Replace as needed. Recommended plug: NGK BR6HS or equivalent.
Air Filter Cleaning:
Clean every 500 km (300 miles) or as needed based on riding conditions. Use Yamaha's recommended cleaner and oil for foam air filters.
Transmission Oil Change:
Change every 3,000 km (1,800 miles) or annually. Use Yamalube Gear Oil (or equivalent SAE 10W-30 API SE, SF, SG, SH, SJ).
2-Stroke Oil Level:
Check oil reservoir level frequently, top up with Yamalube 2-stroke oil or equivalent recommended oil.
Gear Oil Part Number:
Yamaha recommends Yamalube Gear Oil, part numbers may vary but general SAE 10W-30 is widely available.
Engine Oil Type:
Yamalube 2-stroke oil (or equivalent JASO FB, FD or API TC certified).
Transmission Oil Spec:
SAE 10W-30 API SE, SF, SG, SH, SJ (Yamalube Gear Oil recommended).
Brake Fluid:
DOT 3 or DOT 4 (if applicable to specific brake system, though PW50 often uses simple cable-actuated brakes).
Carburetor Clogging:
Can occur due to old fuel or debris, especially if the bike sits for extended periods. Regular fuel stabilizer use and clean fuel are recommended.
Air Filter Fouling:
A dirty air filter restricts airflow, leading to poor performance. Frequent cleaning is crucial, especially in dusty environments.
Throttle Cable Adjustment:
Can stretch over time, requiring adjustment to maintain proper free play for safety and performance.
2-Stroke Carbon Buildup:
Common in 2-stroke engines, can lead to fouled spark plugs and reduced performance if not managed through regular maintenance and proper oil usage.
