No spark

Can anyone tell me the best things to check first and how, I have never done any electric work on a bike so I'm really unsure on where to start and what to do. I went to drive home and it wouldn't start checked and there was no spark after kicking for a while

first thing is a new plug, then check the wires from kill button to the case, even disconnect the kill button. After that its tank off and check ground and wires thereand the plug cap-be sure it is screwed on good. Then its on to the stator and the CDI. The CDI can be cracked by the fork stop not being adjusted right and the forks hitting it.
