It is very easy to do .You need 90wt. hypoid gear lube.First warm the bike up by going for a ride,then get a pan and take the bottom bolt out to drain it.Make sure bike is on the center stand.Now put the bottom bolt back in.Now take the top bolt out and get a small funnel or bend a peice of cardboard to use as a trough and pour the oil in the top hole till it starts to flow out of the hole.Put the top bolt on and your done.You can get a manual for your bike at www.motorbookstore.com and it will help you understand what to do.It has pictures and descriptions on everything you need to now about your bike.You have a nice bike there and with a little work it will run well.I have an 83 that runs like a top! Do spend the money for a manual it will save you time and money.Dont let working on it overwhelm you.It's really rather easy once you understand it.good luck!

All sounds good to me. \\/

Only thing I would add is that the manual says it will take 200-220 ml to fill it. In English, that's 6.8-7.0 ounces.

Gear drive Their is the rear differential & the beveled drive gear assembly Requires removal of the gear shifter & cover to access the drain bolt, 10 mm bolt up to the right is level hole, fill from large plug on top

Lynn, I thought about that, too, but the 650 secondary drive is lubed by the engine oil.
It does not have a separate system like the 850 does.

Steve is right.There is just a drain plug under and in front of the shifter that is 13/16th's.use a box end wrench cause a socket is hard to get in that little space.Use a peice of cardboard to drain the oil into your drain pan and it wont make a big mess on the frame and exhaust. Tighten back up like you would a spark plug so you dont strip it out.Same goes for your oil pan bolt.
