The procedure on ThumperFAQ is for a YZ250F, but the procedure for the '03 model is exactly the same as called for with a YZ450F, so in spite of the size difference, the info applies.

1. get your filters and oil from your friendly, local yamaha dealer.
2. take the dipstick out (this helps the oil drain out faster).
3. undo the drain bolt in the frame, draining the oil.
4. undo the drain bolt in the crankcase (under the shifter), draining the rest of the engine oil.
4. unbolt the oil filter cover, and take out the oil filter.
5. clean the interior of where the oil filter sits.
6. put the clean oil filter back in its proper place and bolt the cover back on.
7. fill the engine with the proper amount of oil.
