Sounds like something electrical!
May have a faulty ground somewhere.
Did you check for spark?

How long has it been since it was ran?
Check compression. and/or
Valves may need to be adjusted.

Also try and clean the pilot jet!
Spray carb. cleaner,
use a trash bag metal twist tie to clean the pilot, and then blow some air through it.

well found out what it was there is two clamps on the carb that hold the air filter tube the first one is right on the carb holding that plastic tube thats the small one then after that there is a big clamp i guess the srew came off while they were riding and the carb sucked in all kinds of sand. i took the carb off and aprayed carb cleaner and it starts right up now so thank you guys for the help:D

Change that oil and check it to make sure there is no trash in it. Hopefully not alot of dirt got in there to mess anything up.
