this weekend i went riding and i submerged my 2010 kx250f and it hydro locked its self. i changed the plug, and my oil it started to run back fired shut off. then after a couple of kicks it would pop not start but pop like a gun going off. changed the oil i just put in it and it was very milky in color. before i did this i for got to mention i took my pipe off and kicked it 20 or so times with out a plug or cap on the bottom of my bike and lots of water spewed out. thats when i put the oil in and started it and it stopped. after emptying my oil i did the same thing emptied the oil took the plug or and my pipe and kicked it no more water. put everything back together new oil and it will not start. just a pop here and another pop after10 kicks or so. just sounds like a 1 shot from a gun. how would i fix this?
