95 yz125 problems. leaking oil

[Nick]

So i see a oil leak developed on my g/f yz we just picked up for her.
I went out to the garage to find i think ALL of the oil on the ground...it kinda looked like it was coming from behind the front sprocket or in that area, there is tons of mud and I didn't make it to the car wash to clean it up yet.
So it it's from behind the sprocket what am i looking at as far as repairs? is it sounding bad?

if it's like the rappy. Right behind he sprocket, the shaft that comes out, there's a seal around that.

I think that's it, I have it upright on a bucket now and it doesn't leak, only when it's on the kick stand and leaning does it leak. I could have over torq'd it when i put the new sprocket on? Would it be called the sprocket seal?

no idear what the official term is for it. I'll look a bit later @ A fIche for it and see if I can find it.
