Stopped really hard, now bike sputters/flat spot

So I took my hawk home today, had to make a hard stop, like 60 down to almost 5 mph. After that the bike ran awful. Seemed like it was out of gas or it was stumbling/flat spotting from 2000-3500 rpm with 1/8 or 1/4 throttle. It would clear up after 3500-4000 rpm and pull hard to 7k, didn't go to redline or anything since the bike was running weird. If I tried to keep it in the trouble range and get on the throttle it'd buck and surge.

I had probably .5 of a gallon of usable fuel left so I'm thinking the fuel sloshed forward and starved the carbs, but I refueled and it didn't fix the problem.

The bike has 14,000 miles on it, manual ccts, and is stock otherwise.

What's causing this issue?

What year is the bike? Also do the float bowl vent lines still go through the stays and cross between the carbs?

2002. I'm unsure on the vent line routing. Can I check that without pulling the tank?
