The "exit" hole on the front cylinder head cannot be seen with the radiator on. Perhaps with a mirror you can see it. I can reach it with my finger though. Looking at the bike from the front, it would be slightly to the right(riders left) and below the crankcase vent fitting where the plastic tube leaves the engine and goes to the air box. there is an identical hole on the rear of the rear cylinder head. If this hole is not clogged up, any water that you put in the spark plug tube should exit this hole. This would be the spark plug on the riders left on the front cylinder and the riders right on the rear cyliner. Keeping the spark plug in place so as not to allow any water to enter the engine, pour a small amount of water in the spark plug tube ( I think it is called a spark plug retaining tube) and see if you can see where the water exits. Once you have located the hole on the front and the rear, run the bike and see if there is any oil coming from the hole. If there is, then the o rings are bad. the retaining tubes can be removed using a 27mm nut (if you cant locate a nut that fits, the rear axel castle nut will work. If the drain hole is plugged, oil will come out of the spark plug tube as it fills up, you can clear the hole and passage with a piece of wire.
