HELP!!! 2007 KFX50 won't start.
 

My son's 07 KFX50 just stalled out today and would not since. It turns over and has plenty of battery juice to start but just wont get running. It happened after my nephew was doing some wheelies. Can anyone think of why? it has gas and the battery is good but seems like the gas is not reaching the carb. Anyone????? please and thank you for helping.

Check that red plug thats used for a kill tether thats on the back of the bike. It might look like its attached,but thet come dislodged very easily.
