Crank the bike when its dead cold and have someone rev the engine until clicking starts and shoot a full stream of water into front header pipe where it connects to heads and see if the noise changes. This should only be done with engine dead cold. If the gaskets are leaking you will definately have a different sound. This check is for the front only, back ones could be leaking also. I had a honda that made that same noise and it was a rod bearing. Hope for best but be prepared for the worst.
