You can drain the outer chamber oil without taking the fork apart , but its not going to get everything out like it would if you tore it down and cleaned everything inside , and you will not be draining the inner chamber
This will get you by as cheaply as possible , though it is not the best for optimum performance as you well know , and only do this if your seals are not leaking
If this is what you want to do then
Loosen the upper triple tree bolts
Loosen the Fork Cap Assembly
Remove the forks
Unscrew the fork cap assembly completely and let the outer tube slightly drop down , but not all the way (just 4"-6")
Tip the fork upside down at a slight angle and let it drain into a pan , leave it there for at least a hour , then turn the fork cap assembly so one of the holes on the side is facing down so it drains into the pan , let it sit for a few minutes till its drained all the way
Repeat with the other fork
Fill with the correct amount of fork oil
Screw for cap assembly back on hand tight
Re-install forks in clamp , only snugging the lower bolts
Snug up the fork cap assembly (just snug not too tight *slightly tighter than hand tight*)
Tighten upper clamp bolt , and torque clamp bolts to proper torque , finish re-assembling everything and go ride
NOTE:
Make sure you let both forks drain the same amount of time so you get as close to equal oil removed as possible
