I just got my 04 400ex on Saturday and it has been riding pretty good. I started it up, went around the block and came back and sprayed all the dirt off from last weekend riding. I then rode around the block a few times to dry it out and came back and noticed an oil leak on the rear where I believe the transmission is. Here are some pics. I hope it's something minor and easily fixable. It does still ride and shift fine but just leaks a lot of oil but only when running it seems.
Please help me figure this out and fix the leak. Thank you in advance for your help.
