Need help changing oil on 06 yz450f

20 posts in this topic

Hey guys,

I recently picked up a really nice 06 yz450f and am in need of doing an oil/filter change. I forgot to get the manual from the guy i bought it from but I called and he is mailing it out. I just need to know like step by step directions for draing the oil. I came off a 02 yz250f so i know how to do the filter and such, but just dont know where to drain the oil from or how much to put back in(Ive heard 1qt???). Thanks in advance for the help.

1> Run the engine for about one minute, and shut down.

2> Remove the dipstick and drain the oil from the oil "tank" at the drain plug located below ignition cover (left side). Replace the plug.

3> Remove the top two oil pump filter bolts, then the lower one and remove the oil filter cover. Service the filter and replace the cover.

4> Drain the crankcase at the drain plug cleverly located directly behind the frame rail on the right side, below the kick starter. (yes, you do detect sarcasm).

5> Fill with 1.1 qts oil, replace the dipstick, start and run for 1-2 minutes, shut down for at least 30 seconds, and check the level.

My new '06 only has 3 oil changes on it but I'm always surprised that it always takes less then the above recommended oil. I do it exactly like Grayracer recommends and then put in one full qt. When I go back to check it's always overfilled so I have to use the drain to get it to go down. Why am I not getting all of the oil out using the above recommendations? I even lean the bike over to the side I'm draining to see if I can get any more out.

Dipstick is the black round plastic thing that stands straight up on the front left side of the motor. It threw me off a little compared to my WR450.

Ours used to show overfill at 1 qt. until we started giving it a little longer to settle down after run up. I think it's due to air bubbles in the return line that keep oil spilling out of the line onto the stick for a bit after shut down.

Well, that probably explains it because it actually kind of bubbles out of where the dipstick goes as if the oil level is rising inside the engine.

Ok I have a few more noob questions....

I still don't see a dipstick, I see the black plastic filler cap but it doesnt have a dipstick on it. I was also wondering how you know when its too full. I guess if it had a dipstick you would know. Is that little bolt in the side the one for checking the fill level?

on a 06/07 the dipstick is right in front of the cylinder on the front of the motor - a black knob :ride:

I just changed the oil in my 06 last night. The dipstick is behind and a little of to the left of the filler cap. There is the black filler cap and then there should be a tall black knob behind it. Its higher on the case too.

its pretty much behind the frame down tube, next to the oil return line in front of your cylinder head.
