How to Change Oil on a Yamaha 450 YZF Dirtbike
If you have any troubles performing this follow the steps provided below.
Make sure the bike is stable, and propped up by something on the forks. This will allow the motor to be free of obstructions.
Place the oil catch pan underneath the motor.
Undo the oil drain bolt; let the oil drain into the pan.
When you are sure that the oil has all been drained, take off the oil filter cover located on the bottom right side of the motor (more oil will come out here) above the frame.
Take off the oil filter and slowly roll the engine over with your hand on the kickstart to be sure all the oil has left the pump system.
Put the oil plug back into the drain hole.
Take your new filter and place it back into the existing position of the previous one.
Put your oil filter cover back on.
Snug up the oil drain bolt and oil filter cover.
Grab your oil and pour it into the oil fill hole located on your frame near the handlebars on the left hand side. When the amount of oil needed is reached put plug back in.
Perform 3-4 revolutions of the motor but do not start it. This is to lubricate all motor parts.
Start motor and let idle until warm (3-5 minutes)
Make sure engine is cold
Always lubricate the rubber o ring with the waste oil on the new oil filter
From empty, bike should have 1.13 liters of oil. NEVER FILL ALL THE WAY!
Never start motor while the oil is drained
Don't let anything other than oil in the oil tank pump or filter
This should be performed every 10-13 hours of riding
If oil is grey or milky this is due to water or burning the clutch when this happens the clutch basket gets so hot the metals start to break up into tiny shavings leaving you with a grey colour in your drained oil
This procedure should take 10 minutes when you get comfortable with these steps
Engine should always be cold possible burn risk
