I'm sure you already know this but your bikes engine must have 3 things to start.
Compression, the right fuel/air mixture and spark.
Have you removed the spark plug, connected the wire and rested the body against the cylinder head while kick starting? You should have seen a nice big blue spark at the electrode. If you didn't you've found one of your problems.
No spark can be caused by a low battery voltage, transmission not in neutral, the side stand down (in later models with a side stand switch), dirty or incorrectly adjusted ignition points, blown fuses....
The list goes on.......
Is the engine getting fuel? Sniffing the freshly removed spark plug can give a good indication.
If there is no fuel smell it's possible your fuel tap (off/on valve) on the tank is plugged with dirt or rust, the carburetor needle valve is stuck shut or the fuel tank lid is not letting in any air.
If these things seem to be operating OK you might try carefully pouring 1/2 teaspoons worth of gasoline down the spark plug hole, reinstalling the spark plug and giving it a kick. It should fire at least once.
If the spark plug is wet with fuel the engine is flooded.
If so, make sure the choke is off and the decompression release is on.
Then, with the throttle wide open kick the engine thru at least 4 full kicks.
Usually, kicking the engine thru is not fast enough to draw much if any fuel thru a wide open carburetor so the carb won't add any fuel and all the fresh air will remove a lot of the excess fuel in the cylinder.
You might want to leave the ignition on while doing this because often when things get dry enough the engine will fire.
