Re: Leaking antifreeze
That is a drain hole. It keeps water from accumulating in the spark plug area. If anti-freeze is coming from that hole it is starting someplace else.

If that's the left head the leak is likely up above at the water tubes or thermostat housing since everything would drain that way with the bike on the sidestand.

Re: Leaking antifreeze
Crossover tubes is the usual suspect. Backyardbob used to sell a ORing kit on flea bay just for this and it only cost a few bucks. do a search for "huntech2006" might have to shoot him a not there and tell him you are looking for them.

Or, it could just be doing it's job and draining water that collected in the plug hole (rain, wash, etc.) IF it is just water.
