strange running problem
I have an '03 hawk w/ 13k and tonight after fueling the bike started running
on 1 cyl. then die at a stop. I limped the bike home about 3 miles, during this time I would feel the other cyl kick in, but only briefly. It sounded like a thumper on crack!!! By the time I got home it started idleing, but would backfire terribly. I checked the spark plugs, not fouled. No indication of flooding. I put the bike back together and now it seems to be running great. I don't think I over filled it. I put some seafoam in the gas thinking I had a vat of bad gas. What do you all think???

I think you did fill it a bit too much, or wheelied or stoppied soon after the fill-up. You had what's called vacuum lock, where fuel gets into the tank vent and then as fuel is used a vacuum is drawn in the tank. Since the vent line has fuel in it air cannot get into the tank. The vacuum prevents fuel from flowing to the carbs. Next time it happens, pull over, open and shut the filler cap, then be on your way. Shouldn't happen twice in a row.

Because I am THE MAN! Don't question my authority, son!
Just kidding! I've been on some form of Superhawk email list or forum since 1998 when I first got the bike. I've read a LOT of information about it, people's experiences, and my bike has never been to the dealer since I rode it off the lot. I'm a Navy mechanic by trade (nuclear) so I think I have somewhat of a clue when it comes to things mechanical. I don't think I've ever steered anyone wrong here and if I don't know the answer I've no problem saying so.
