Hondas leak oil?
No, but old engine seals do if left to rot!  Well, in this situation it's a blown head gasket around the 3rd cylinder, and a misaligned header from the wrong model, I think.  Either way, it's frustrating because the bikes have moved around so frequently, I worry that one of MY bikes may be leaking oil, which they are not.  Currently my CB500K-0 is parked above one of the 750s' previous puddles.  
I think I'll just drain all the oil from the 750 so it stops leaking...fat chance.  Like a dog will still poop even if you stop feeding it, no matter what.  One of those things, I guess.
