It's only been 11 year since this post was living and breathing...... so, I'm chiming in too. I JUST finished and R&R of gear lube in the final drive of my 05 RSV. The maintenance manual calls for 200ml of 80w gear lube, GL4 or GL5, etc... 200ml is 6.75 Fluid Ounces and I used the genenric Walmart brand of 80w90. Like others, I will change this each oil change too. It's too easy..... espcially with the following set up.
Pictures are a couple of ubiquitous items every maintenance guy should have in his shop. I found the hosed funnel fits PERFECT from the back and the hose snakes down to the filler perfectly. I mean like it was made for it. And the funnel itself is tipped up enough so you can feed it a little, wait a few seconds, feed it, etc.... Since the FD only required 200ml...... I put 220ml in the Ratio Right and when the flowing stopped, I pull the hose and directed it to the drain pan, and put the plug back. (By the way, both plugs are 17mm.) The reason I use 220ml instead of the 200ml is...... I don't have to sit around for an hour allowing every drop to flow into the FD. The moment the majority has flowed in, pull the hose, add the plug and the job is done. I, like others have noted here, is a touch rotund and nearing 60yo and don't want to get up and down and up and down either. You can set this setup up prior to hitting the floor and go down and up ONCE ! You can thank me later.
I hope this helps someone.
