Does the fuel pump turn on when you turn the key on? If so, take your spark plugs out of the cylinders and turn the bike over. See if any gas mists out, if so your getting fuel. Then again check your plugs and make sure they're arcing. If they are then put them back in.
If the bike doesn't run then, try unplugging your tuner if you have one. like stated already, check all your fuses, and make sure there's no cracks or holes in any of your lines or breathers, allowing to much air in.
