I don't know how much you know about checking them etc., but if you need help, just let us know.
That tank looks HUGE - I would guess the only real way to find out how much it holds is to drain and refill it unless someone here can identify it.
Aside form needing a rear tire, it looks in great shape for a 10 year old bike.

Remove the oil filter cover and change the filter.
Pull the drain plug on the bottom
and last but not least, remove the external oil line you see under the oil filter, gravity drain it all for half an hour put it all back together and add the required amount of oil.
My 400 takes:
1.5 for frame and case drain
1.6 for frame, case and oil filter
1.7 for a complete oil change as above

it sounds to me as though you are not draining the oil from the frame and the sump... maybe I am wrong???
how, besides suction , do you get all the oil out of these things.

If you are concerned about increasing the mid-range hit going to YZ timing, remember, with the stock cams it's only about an hour to change it back. Decide what you like, and then order the appropriate auto-decomp cam (03 WR or YZ, depending on which timing you like best).
Finally, the tank looks to be either a Clarke or IMS, and should hold 3.5 gallons, smae as stock, just a better (narrower) profile. It also has a YZF seat (required to run that tank).
Ride the piss out of it!

Warm it up.
1: open refill cap, then open frame drain bolt.
2: open under engine drain bolt
3: open the bottom bolt (lowest) on the oilfilter cap
4: loosen hose clamp that goes from the frame to lower right side of engine, remove the oilpipe where it's fitted to the engine, then remove the oil strainer that the hose was fitted.
To really get the last drops of oil out you can lean the bike from one side to another.
Now you're completely empty and can remove the oilfiltercap and clean/replace oil filter.
