I have an 03 Vulcan Classic carb'd 1500. Is it possible to put an 04 Mean Streak 1600 fuel injected engine in it? Or any other fuel injected Vulcan engine?

I am asking here because I searched and have read that it is possible to put a fuel injected engine in a carb bike and with just a couple extra holes drilled to make the conversion back to carbureted. I would prefer to keep it carb'd if that is less work. Is this a possibility?

So from those of you who have done the conversion or are familiar with swapping an engine..... do you have any pics of the holes or mods? Or how much of a task is it?
