To start the Yamaha PW50 after it has been sitting for a long time, ensure the fuel is fresh, check the spark plug for fouling, and make sure the battery is charged. Use the choke if necessary and kick start the engine while applying a little throttle.
The recommended maintenance schedule includes checking and cleaning the air filter every 10 hours, changing the transmission oil every 20 hours, inspecting the spark plug every 10 hours, and checking the brakes, cables, and tires regularly.
If the Yamaha PW50 won't start, check for fuel in the tank, ensure the fuel valve is open, inspect the spark plug for wear or fouling, verify that the kill switch is in the correct position, and check the carburetor for clogs.
Use a high-quality 10W-30 or 10W-40 motor oil for the Yamaha PW50 transmission, ensuring it meets the JASO MA standard for wet clutches.
Improving the performance of a Yamaha PW50 can be achieved by ensuring regular maintenance, using high-quality fuel and oil, adjusting the carburetor for optimal fuel-air mixture, and upgrading the exhaust system if necessary.
If the PW50 is idling rough, check the air filter for clogs, inspect the spark plug for fouling, and adjust the idle screw on the carburetor to achieve a smooth idle.
To adjust the brakes on a Yamaha PW50, locate the brake adjuster nuts near the brake levers, and turn them clockwise to tighten or counterclockwise to loosen, ensuring the wheels spin freely without excess resistance.
Common signs of a worn-out spark plug include difficulty starting, engine misfiring, reduced performance, increased fuel consumption, and a noticeable change in exhaust sound.
To clean the carburetor, remove it from the bike, disassemble it carefully, and clean each part with carburetor cleaner. Make sure all passages are clear before reassembling and reinstalling it.
