Today I was riding like always and in one corner my bike had a big bog. Then I was riding fast and when I stopped the bike died. I was trying to start it but it started only on hot start. It had idle but died on throttle blip. When I'm riding everything is ok but on idle it dies and on throttle blip from idle also.
What could it be?

A small amount of water in the fuel can cause this. So can a flake of rust. Drain the carb and catch the fuel for examination. It you see water, dump 2-300cc of ethyl or isopropyl alcohol into the tank, then fill it with fresh fuel.
