How often should I change the air filter on my CRF150F?

What is the correct tire pressure for the CRF150F?
For off-road riding, front tire pressure is typically 15 psi (1.0 bar) and rear tire pressure is 15 psi (1.0 bar). Slightly lower pressures improve traction on soft terrain, but always verify with the manual.
How do I adjust the chain slack on the CRF150F?
The chain should have about 20-30 mm of free play at the middle of the lower run. Loosen the axle nut and adjust the chain adjusters on both sides equally, then retighten. Refer to the maintenance section of your manual.
Is the CRF150F street legal?
No, the CRF150F is a competition/off-road motorcycle and is not equipped with lights, mirrors, or street-legal tires. It is designed for use on closed courses and trails only.

Use unleaded gasoline with a pump octane number of 86 or higher. Regular unleaded fuel is fine; do not use ethanol blends above E10.
How do I start the engine when it is cold?
To start a cold engine, turn the fuel valve on, pull the choke lever, shift to neutral, and press the electric start button or use the kickstarter. Once the engine warms up, turn the choke off gradually.
What is the valve clearance specification for the CRF150F?
The intake valve clearance is typically 0.10 mm and exhaust valve clearance is 0.15 mm when the engine is cold. Always measure with a feeler gauge and adjust as per the maintenance schedule.

What is the recommended break-in procedure for a new engine?
