Wierd smoke

I have a jet star 3 super that when it runs and is shut down it has a white smoke pour out of the hood, it doesn't smell like burning oil, belt or antifreeze, it doesn't heat up past 170 what could it be?
 
It could possibly be coming from the crankcase breather. That is a place I would check as it might be blow by.

It's coming off the manifolds, and it only does it when it's hot, I have taking the oil cap off to see if it was blow by but it is not blowby
 
If it's white, I would bet it is coolant. Is it a
pressurized system? It may be squirting out onto
the manifold from a leaky gasket or hose. I was
running my W-30 MD one day & I could feel a mist
every once in a while. I finally got to looking &
the head gasket had split at the cylinder ring. It
was non-pressurized, so when it went into
compression it would blow coolant out between the
gasket layers to the outside.
