How can I fix my son,s 50cc neo,s two stroke2009 scooter?

I had a similar problem with a Yamaha Majesty & it was a intermittant dodgy brakelight switch inside the brake lever. If it's nots starting using the left lever then try the right one. If it's still not starting, check if the brakelight is coming on when you pull in either lever assuming the bulb is okay, you'll know then if any switches need replacing.
