newbie that needs help!

I have an '02 400ex and it looks like I have a small oil leak behind the drive sprocket. Does anyone know what that could be from? I was going to take the sprocket off and look but I could not find the torque value for the bolt.

it smore than likely the seal behind the sprocket where the shaft come out. correct me if im wrong. but thats what id think it would be.

is that something thats hard to fix? Do I have to pull the crankcase cover?

Take off the front sprocket to gain access to the seal, use a pick to pull it out and replace it with a new one, it's easy.

Does anyone know the torque value for the two bolts that hold on the sprocket? I have the 400ex manual on PDF but it does not give the torque value, or not even how to get the damn sprocket off. But it shows how to replace the final drive gear.:huh
