Yamaha FJR13AEY C 2009 Owner's Manual

To check the engine oil level, place the motorcycle on a level surface and allow the engine to warm up for a few minutes, then turn it off. Wait a couple of minutes for the oil to settle, then check the oil sight glass located on the right side of the engine. The oil level should be between the upper and lower marks.
For optimal performance, the recommended tire pressure is 42 psi for the front tire and 42 psi for the rear tire. Always check the tire pressure when the tires are cold.
If your motorcycle is having trouble starting, check the battery connections to ensure they are tight and free of corrosion. Verify that the kill switch is set to the 'run' position, and check the fuel level. If the problem persists, inspect the spark plugs and fuel lines for any issues.
Use a high-quality ethylene glycol-based antifreeze coolant with corrosion inhibitors for aluminum engines. Ensure the coolant is mixed with distilled water at a 50/50 ratio.
The air filter should be checked every 6,000 miles and replaced if necessary. In dusty or harsh environments, more frequent checks and replacements may be required.
To adjust the suspension, refer to the owner’s manual for the specific settings for preload, rebound damping, and compression damping. Adjust each setting according to your riding style and load conditions.
To change the brake pads, remove the caliper bolts and lift the caliper off the rotor. Carefully remove the old brake pads and install the new ones. Reinstall the caliper and torque the bolts to the manufacturer's specifications. Check the brake fluid level after installation.
Perform regular maintenance every 4,000 miles or 6 months, including oil changes, chain lubrication, and brake inspections. More comprehensive checks like valve clearances and spark plug replacement should be done every 16,000 miles.
To improve fuel efficiency, maintain proper tire pressure, ensure regular maintenance, and avoid aggressive acceleration and braking. Riding at a steady speed and reducing excess weight can also help.
If the motorcycle overheats, pull over safely and turn off the engine. Allow the bike to cool down before checking the coolant level and inspecting for leaks. If the problem persists, consult a professional mechanic.
