it turned out to be spark plugs or ignition coils. we changed both right before i went out for the last bit of practice before the race. i was blowing corners pretty bad because i finally had more power. i instantly increased my times by a second to a second and a half without much practice with the new, more lively bike. too bad i couldn't keep it together and i had to chuck myself down the track and break my neck, wrist, and hand.
but i'm back and feeling and riding better than ever.
