Fork Oil Removal?

You could always turn the bike upside down and let the oil drain out that way.

I'll get me coat....

 

Did mine several months ago, I removed the forks as I was also fitting gaiters and changing the oil.
Straightforward job really, take the forks out one at a time to help keep alignment and allow yourself a couple of hours. Undo the 22mm top cap before taking out.
I looked at undoing the damper rods but personally I would not recommend it as you may struggle to get the bolts back in and tightened.
whatever happened to plain old fashioned drain plugs?

 

As @MickEng says the problem with removing the damper rod is torqueing it all back up again, if the screw binds at all then it all goes round inside and no way to hold the rod still.
Can be the same issue removing it too, plus you'll need new sealing washers ...... much easier to remove the whole leg and tip it upside down.

Or use the giant syringe method as mentioned by @Dozers Dad

 

Oh yes, I know where it is, but I personally would not recommend removing that bolt.
You have to remove the spindle, wheel and brake caliper so you are already half way there to taking the forks out.
Go for it Beardy!
