Start basic, check for fuel, spark, and air.

Is there a whining/whistling noise coming from your cdi box when the key is in the on position? If not, then it is likely the box is bad.

 

yes it is in the same time than the antenna , radio , etc.... sound like a light whiiiiiiiiii!

how do you check for fuel?

Remove the air filter and with the key on, see if there is pressure on the fuel plate by pushing on it. If it pushes up with no effort, then there is no fuel. If it pushes up, but there is resistance, then the fuel pressure is probably ok.
