from inside the hub or from the nuts on the outside.

If your hub oil is leaking out, it would not likely be black, but could be picking up break and road dust.

Check to make sure all of the external nuts are tight.

It is is internal, you are in for a much bigger job.

Here's an obvious (to me) question...

Did you ensure the plug is tight?

When was the last time you changed the hub fluid? New crush washer? If not, and you torque it, it won't be tight enough and will leak. If not leaking from there, I agree with SQ that you are leaking from the hub and probably have a bad seal.

I would tighten the plug about 1/8th turn. Sounds like it's leaking from around the crush washer. This should crush it down a little more so it seals. If it still seems to be leaking from there, change the hub fluid and get a new crush washer, then torque the plug to specs.

If it's more of a grease than oil, and kind of dirty, it may be coming from inside the hub. Mine had some extra grease on the splines, as in enough to grease at least two of them, and it would work out over time. By the time it got slung onto the wheel it had collected enough brake dust that it no longer looked like grease. I actually kept a long, thin piece of cloth around for when I cleaned it, and I'd loop the cloth around the gap between the final drive and wheel to clean it out before it got slung off.

It quit doing it after I changed my first tire on the back and cleaned the excess grease out.

/sorry for the slight jack

Is the crush washer from the hub oil drain bolt something you can get a hardware store? What size would I be looking for?

Just had the hub and wheels chromed and it's leaking at the washer. Im in another state and can not get to the dealer till Monday. Would like to fix it tomorrow cause it's messing up my new wheels:D

If you take the old one with you, you might be able to match it with one at an auto parts store.

If you have a Yamaha dealer nearby, you can get the crush washers from them. They use the same thing. seapup posted this a long time ago. They are less the $1 each and you can buy singles or packs.

Yamaha crush washers (part #214-11198-01)

Picture of the package, the diff uses the same as the engine oil drain plugs.

I have been using those washers since day one with no issues.
