I was riding it one day and it shut off and when i kick start it, it only has a little bit of compression and it backfires when its being kicked, what is wrong with it? i dont think anything broke in the engine because nothing broke when it shut off.. its a 99 kx 125, it has spark and enough compression to start.. it just wont
 
Let me get this straight..... First you said it has a "little bit" of compression... Bu then it has enough compression?
Sounds like you have a bit of water in the line, or may need a new spark plug wire. Try using some dry gas and/or replacing the spark plug wire. Could also be a bad carb. try taking the carb off if those two things don't work and replace or rebuild it.
 
Sounds like carb problems

ck air filter also

A little comp but enough ????????????
 
If the compression dropped dramatically, you burned a hole in the piston is my #1 Guess.
