If your tank was full there shouldn't be build up inside. Like you, I was a little sloppy with my shut down for the year as I was riding right up until they put salt on the road. I didn't run the carbs dry with the petcock off like you're supposed to. I did put Stabil in it however. It ran fine when I fired it up and I found no discernable choppiness or stuttering.
Not something I would do as a habit if your bike sits for a long period of time but if it starts, ride it and run it for a while. If the bike seems to handle fine, just fill it up and add some Lucas gas treatment every other tank.
If it runs choppy, drain it.
