fully charge your battery as you will need it chances are its crap fuel in the lines if its been stood turn the bike over and keep the button pressed for quite some time while messing with the choke on and off some bikes hate crap fuel and the only way to start it is the way above do not open the throttle as it will just weaken the mixture and not fire you will get good fuel through eventually it will run crap when it does fire up but just keep it running till it warms up properly if after doing the above and it still doesnt start you will probably have to remove the plugs and give them a good clean up before proding further in to it also is your bike fuel injected or carbs ? if its carbs it could be a different story
