I have a 2010 yz 450 I recently had the bike lock up do to the timing skipping a tooth from a loose chain. I put a new timing chain on and respeced the valves everything appears to be at the bottomend of the tolerence scale for the bike but when i got to kick it the engine turns but the the kickstarter flys back up at about 100 miles an hr feel like it wants to break my leg on way up. Any suggestion on why it would do this would be greatly appreciated completely stuck never had this problem before

This might be a stupid question but you aren't giving it gas while kicking are you?
