I have never seen a 1500 with the covers off, but if it has the water pipes with o-ring seals across the engine like the 1000's and 1100's, it is probably one of the o-ring seals in these pipes. They are the most common leak on 1000's and usually give more trouble in cooler weather.

There's two very short pipes going to the carbs to heating them. They are under the carbs and very hard to see them, MAYBE one of them is leaking, and when the bike is on it's sidestand, the fluid flows to the left head. I'll see what about the O-rings around the head...

I checked the manual but it's not clear if the pipes going across the end engine or not. If there are water in the head and oil too, O-rings and the head gasket can cause the problem. If the water is only on the outer surface, check the pipes. Check the manifold, it's also heated.

Found my problem , it was the top " Y " hose connecting at the thermostat cover that had a loose clip .
