1999 Honda 400ex fuel problem?

Was riding last nite, bike was running fine came back to camp let sit bout 20 mins. Got back on it and it started fine but when I gave it a lot of gas it just kinda bogged down. Maybe it was hot? Or Crap in the tank maybe? Help! Still out riding!

It runs fine at low rpms, but when you hit the gas it has no power

Did you fix your issue? Thread was posted in the wrong section.
