Yamaha TW200N C TW 2001 Owner's Manual

To maintain the chain, regularly clean it with a chain cleaner and a soft brush. After cleaning, apply a suitable chain lubricant while spinning the wheel to ensure even coverage. Adjust the chain tension to the specifications in the service manual (20-30mm slack at the tightest point).
Use a high-quality 4-stroke motorcycle oil with a viscosity rating of SAE 10W-40. Change the oil every 3,000 miles or every 6 months, whichever comes first, and replace the oil filter every other oil change.
Check the battery voltage and connections, ensuring they are clean and tight. Inspect the spark plug for fouling or wear and replace if necessary. Verify that the fuel petcock is in the correct position and that there is sufficient fuel in the tank.
The recommended tire pressure is 22 psi for the front tire and 25 psi for the rear tire. Always check the pressure when the tires are cold for accurate readings.
Ensure regular maintenance, including air filter cleaning/replacement and proper tire inflation. Ride smoothly, avoiding rapid acceleration and excessive idling. Use the recommended grade of fuel and avoid carrying unnecessary weight.
Check the brake fluid level and top up if necessary, using the specified DOT 3 or DOT 4 brake fluid. Inspect the brake pads for wear and replace them if needed. Bleed the brake system to remove any air trapped in the lines.
Adjust the rear shock preload to suit your weight and riding style. Use the adjuster ring on the shock absorber to increase or decrease the preload. Refer to the owner’s manual for specific adjustment instructions and recommended settings.
Remove the seat and fuel tank to access the spark plug. Use a spark plug socket to unscrew the old spark plug. Check the gap on the new spark plug and install it, tightening to the specified torque. Reassemble the tank and seat.
Check for proper coolant levels and inspect the radiator for clogs or leaks. Ensure the cooling fan is operational. Avoid extended idling and keep the engine clean to prevent overheating.
Locate the idle speed adjustment screw on the carburetor. Start the engine and let it warm up. Turn the screw clockwise to increase the idle speed or counterclockwise to decrease it, aiming for an idle speed of approximately 1,400 RPM.
