If you're referring to the oil screen tube in the side drainage port by the kickstand, it's easy to pull out. The tricky part is re-seating it after the oil is drained.
Insert a screwdriver through the tube and guide the tube in until it is flush with the opening. There is a little lip on the far wall the tube will seat on. SLOWLY AND CAREFULLY back out the screwdriver while holding the tube in place. Pause to move the screwdriver up and down inside the tube. If the tube is not seated and gravity keeps it attached to the screwdriver, it can fall into the oil pan if you pull the screwdriver out too far. On the other hand, if it doesn't move when the screwdriver is NOT touching the inside of the tube, and the tube is flush in the hole, it's seated.
If you miscalculate and the tube falls down into the oil pan, buy a claw tool for $7.95 that fits in the drain hole and fish it out. It may take time but it's doable. There are quite a few threads on oil changes and several address this issue and have illustrations from the Service Manual.
