[400EXracer74]

today i was riding at my friends dirt bike track. it was sick, the jumps were so much fun. A 60 footer and a 50 footer are sick. but then i came down off of the 60 footer and pulled in the clutch and went to down shift and the thing stalled and wouldnt start. then i would start and run for like a second and then die and if i tried to rev it nuthing would happen. kinda like there isnt any compression but i dont know that much about engines. so when i got home i cleaned the spark plug and that didnt change at all. then i emptied the oil and it smelled like gas. i dont think that is good at all. so if anyone can help please do

Im sorry... But I have to ask... Is there gas in it?

check if its getting spark, fuel, air. Then check to see if the carb came off the airboot. Visually check all of the things on the entire engine/intake. Then, take your carb off, maybe your main jet came loose. If the carb is fine... Then its probibly internal.
