The recommended oil for the Yamaha XV250B C Star 2012 is SAE 10W-40, API service SG type or higher.
The air filter should be inspected every 4,000 miles and replaced if necessary. A replacement is typically recommended every 12,000 miles.
The recommended tire pressure is 28 psi for the front tire and 32 psi for the rear tire when riding solo.
If the bike won't start, check the battery charge, ensure the kill switch is set to 'Run', check the fuel level, and inspect the spark plugs for wear or fouling.
To adjust chain tension, loosen the axle nut, adjust the chain adjusters evenly on both sides until the chain has about 20-30 mm of slack, then retighten the axle nut.
Check the brake fluid level by looking at the sight glass on the master cylinder. The fluid should be between the minimum and maximum marks.
If the engine overheats, stop and let it cool down. Check the coolant level and inspect for any leaks. Ensure the radiator is not blocked.
Spark plugs should be inspected every 4,000 miles and replaced every 8,000 miles or as needed based on their condition.
For long-term storage, clean the bike thoroughly, change the oil, fill the fuel tank, disconnect the battery, and cover the bike with a breathable cover.
To adjust the idle speed, turn the idle adjustment screw located on the carburetor until the engine idles smoothly at around 1,200 rpm.
