Hypoid just means spiral bevel gear, (as in most any rear end) and 80/90 or the next step up would be fine as well.

My preference is to use a synthetic gear lube intended for automotive rear ends, such as Mobil 1 LS 75W-90 Synthetic Gear Lube. I've noticed my bike's rear end runs cooler and quieter using this as opposed to a non-synthetic lube.
Whether you choose to use a synthetic or not, use a gear lube intended for automotive rear ends. A standard oil will not stand up to the extreme conditions in the rear end.

I'm sure just about anything in there would be fine. Since it's not hard to change why not try what you want and if you want a second opinion buy another quart of something else and see how it works.

Fill until it comes out the hole basically I'm guessing?

Drain out the little hole and fill with the big hole. and yes till it gets up there. It's seriously a small amount.

Yeah, but what it calls for (straight weight - SAE90) is not so common anymore...They type of drive oil is embossed on the drive casing![]()

Here is the states it is hard to find a straight SAE90 or SAE80. Most are sold as 75w90, 80w90, etc. Important thing is that it is Hypoid Gear oil...
Discussed in length on the old forum (as you know), of course those threads are currently 404'd when you try to bring them up.
