Ok so I was just crusing down a trail in 2 gear and my bike made a loud cracking sound and just shut off and now it wont start. I was thinking that it was the valves because it had barely any compression when i started it and it back fired alot..whats the most likely problem?

^Timing would be my guess also.  Do a search in this forum and you will find some details on how to check the timing.

ya i would say piston problems..  at very least you need to take the top end apart and check everything.
