Try removing the the throttle body and underneath it where it bolts to the engine you will find the reed block,lift this out of the engine and hold it up to the light if you can see light through the reeds and the housing it needs either cleaning if its debri or replacement if its worn out. if open the engine looses the compression and it wont start at all. mine did this and i couldnt beleive that it could have stopped it. good look

if you have checked the spark and its ok i would remove the throttle body from where it bolts on to the engine and underneath that is the reed valve this will just slide out of the caseing. hold it up to the light and looking through it from the hollow side see if you can see any light shining through the reeds, if you can it will be this, if its just a peice of dirt holding it open clean it out and make a good seal. if its worn you will need a replacement.the bike should start.
this valve creates a seal when the piston is on its downward stroke which creates crankcase preasure this pressure is lost if the valve is worn out or stuck open.
