Yamaha TW200T1, TW200T1C TW 2005 Owner's Manual

For optimal performance, change the oil every 1,000 miles or every 6 months, whichever comes first. Use the recommended oil type specified in the manual.
The Yamaha TW200T1 is designed to run on unleaded gasoline with a minimum octane rating of 91.
To adjust the chain tension, ensure the bike is on a stand, then loosen the axle nut and adjust the chain using the chain adjusters. Aim for around 1.2 to 1.6 inches of slack in the chain.
Check the fuel level, ensure the kill switch is set to 'run', inspect the spark plug for fouling, and verify that the battery is charged. If it still won't start, consult a professional.
To replace the air filter, remove the seat and side panel, access the airbox, and replace the old filter with a new one. Ensure the new filter is seated properly before reassembling.
The recommended tire pressure for the TW200T1 is 18 psi for the front tire and 22 psi for the rear tire when riding solo. Adjust as necessary for load and conditions.
Maintain proper tire pressure, use high-quality fuel, regularly clean or replace the air filter, and keep the engine tuned to improve fuel efficiency.
Overheating may be caused by low oil levels, blocked air passages, or a dirty carburetor. Check and address these issues, and ensure the engine is not overloaded.
Before storage, clean the bike thoroughly, change the oil, fill the gas tank and add a fuel stabilizer, disconnect the battery, and store the bike in a dry, covered area.
Valve clearance should be checked every 4,000 miles. Properly adjusted valves ensure efficient engine performance and longevity.
