2013 yz450f wont start

My bike only has 13 hours on it...today at the track as I landed from a jump I stalled and now it will not start..I had to push it off the track after I got home I tried starting and still nothing.. always started on second kick..any ideas what it could be?

Verify spark. If none check over the harness for a broken wire or loose connection...

Un hook the kill switch. Mine did that also hopefully its that simple

@domdomfielding1 genius it was the kill switch. Thanks

Having this same problem with a 2012. Tried kill switch. Any other ideas.

Hey rzr33, have you checked for spark, fuel , air? Do you have all that? My 2010 yz450 recently didn't start either and when I took it apart I noticed that the flywheel was rubbed open.

Yep. Has spark and fuel.

Try to check your flywheel anyways. I had spark on mine too but not enough.ImageUploadedByThumper Talk1409897723.127290.jpg that's how my flywheel looked
