I was out riding the other day for a few hours, stopped for about 10 or 15 mins. to take some videos. When I got back on my bike and went to start it, it took a few kicks, and a couple of times the compression kicked the kicker back at me pretty hard. Then when I got the bike started and just barely let out of the clutch to start moving, there was a pop, or something, and it stalled, then when I tried to kick start it, there was no compression, and kind of a rattling in the top end.... Any idea what might have happened? I didn't have any problems with the bike up until this point...

Pull your sparkplug first and look for signs of damage. If the sparkplug is damaged you probably ate a valve.

Thanks, I'll do that (and hope its just the timing)
