so i was at the track today making some major improvements on my turning abilities. when i went off a jump and in the air the bike revved out of control all by itself so i pulled in the clutch shut it off when i landed. i tried starting it again and it was kicking back. i got a few full kicks in but they sounded empty and didnt feel normal. no visible damage. someone at the track said it is my valves. i think it might also be leaking anti freeze but its coming from the case. if you need pictures i can take some. plz help.
