There's a couple of basic things you need to do.
#1--After kicking it a few times (3-5 should be goood), pull the plug and check to see if it's wet. If so, you've got excess fuel in the cylinder and will need a new plug (this one is fouled now).
#2--If the plug is dry (It MUST be brand new--not used once or twice), put it back into the plug cap, lean the electrode part (end that goes into the engine) up against the cylinder head and kick a few times (5 or so should be good) at the same LOOKING closely at the electrode for a nice blue spark.
#If you get a good spark and the plug WAS dry when you pulled it out of the head, put a couple of tablespoons of fuel from your gas tank into the head, screw the plug back into the engine and reattach the plug cap. Kick the bike a few times, it SHOULD try and run.
Let us know how this goes or if any step above isn't as it should be, report back.
