Both engine lubricating oil and gasoline are introduced into the combustion chamber when the engine is running - so it is not impossible that a *small* amount of gasoline could end up mixed with the oil.
The most common cause of oil becoming diluted with gasoline is idling - when the engine is cold there are greater clearances between the piston rings and the cylinder walls, and this greater clearance allows small amounts of unburned fuel to slip down into the crankcase. For this reason, most experts recommend trying to avoid excessive idling. With a EFI bike like the V-Rod, you can usually start her up, and in the time it takes to zip your jacket and adjust your glasses, she's ready to ride - obviously don't push the engine too hard till its warmed up - but its best to warm the engine through moderate riding, rather than sitting at idle.
Since gasoline is lighter than lubricating oil, any gasoline mixed with the oil will tend to float on top. For that reason, when you drain your oil and look at the container even a few milliliters of partially burned gasoline will be very apparent. Obviously, this dilution of the oil effects its lubricating properties - as well as the corrosive effects of the other nasty chemicals in partially burned gasoline.
Change your oil frequently - 2000 miles is (IMHO) the absolute maximum you should ride between changes.
