What it will do is warm up the air inside your motor enough that condensation will accumulate on the internals of the motor. Unless you are going to be running that motor for a good 30 minutes or so, that water wont have a chance to burn off. The air inside the motor is going to heat up faster than the metal of the motor.
Warm air + cold metal = condensation..... Just like a glass of iced tea during the summer.
I'd just leave it sit till the first ride of the spring.
When spring comes around:
Pull the plugs,
Pull the oil dipstick,
Look inside the oil tank,
You'll notice that it appears the oil level is low, but DO NOT add oil at this time.
Oil level appears to be low due to the check ball has let some oil seep into the crank case.
Softails are noted for this when they sit for extended periods due to the oil tank being higher than the crank case.
Crank the motor over without the spark plugs installed while watching in the oil tank rise to its proper level.
Re install spark plugs and go for your first spring ride.
