I recently cleaned the carbs out on my 1990 katana 600, they were filthy, so we cleaned them out, also cleaned the gas tank and put a new petcock on. we ran the bike 8 miles and it started popping out and then died. we took the carbs back off and it had lots of dirt in it again? what should i do? what are some problems to consider? could it be a fuel line problem?

I dont think your tank is clean, get some kerosene slosh it around remove the fuel valve clean the filter that is atached to the fuel valve and purchase cream which is a three step process to reline your tank good as new. also since you removed the carbs to clean they need to be synchronized.
