Nope. It's either on when the engine is pulling a vacuum or off when the
engine is off. I'm going from experience with the later bikes, though.
In addition to normal and reserve positions, the newer bikes also have a
"prime" position to bypass the vacuum controlled valve. I expect you have
the same, or starting up after a long lay-up would be a pain.
