Shooter:
Thanks, I'm well aware of that. Point I'm trying to make is that even that is unnecessary. I'm only talking about the non-cartridge front ends here. I've never messed with one of the newer fork tubes (left side if I remember correctly) with a cartridge in it so can't talk to them. New fork oil can be inserted thru the drain hole using a MityVac or large syringe. You will lose a slight amount getting the drain plug back in but just add a bit more to start with. Now the purists will say you might wind up with a difference in amounts in each side. I have always contended that it's never the same anyway because of fork oil left behind in the tube after draining and in the fill container after filling. There is just no way to accurately measure the amount of oil left (kling effect) in either one. Lots of shops and individuals do it this way and have been for years. Never did understand HD theory in listing a measurement like 11.1 and 10.7, etc. In the older service manuals, it would list 2 quantities, 1 for dry fill and 1 for wet fill. Now it doesn't.
I don't buy the complete disassembly approach posted by fxer above.

The Mityvac is just a hand operated vacuum pump that will allow "push" by changing the location of the line. Very useful for brake bleeding, connect to petcock to create a vacuum to drain the gas from tanks, and to fill forks with fork oil. See www.mityvac.com. You can also get them thru some auto parts stores, NAPA, I think.
Da*n Gunny, if you ain't got enough callouses on the hands to handle that little bit of pumping, it's time to practice some more.
Seriously, it's easy with Mityvac, course my hands are tough.

Grayghost: I don't have a 03 Service Manual. If your friend doesn't, it is a "MUST BUY" item. I believe that the service manual does say you have to do that but see one of my posts above about filling thru the drain plug. I just don't know about the left fork with the cartridge in it. Never dealt with one of those.
Maybe someone else on here has and can shed some light on it. Taking off the fairing, at least the outer fairing, is real easy. however, don't think that would let you get to the fork caps without taking some other stuff off.
