I would check to see if your getting spark first. If not something in your ignition system is wet or shorted from being wet. Dry it out. Blow air in the spark plug wire cap etc..
If you have spark, check to see if you are getting fuel to the combustion chamber. Even squirt a little gas into the spark plug hole if you have to.
If you have fuel and you have spark it should at least start or try to start. Whether it will continue to run or run well is another matter... --RR

You dropped it in deep water. Was it completely submerged? Did water get in the airbox? How much water do you think your bike ingested?

I would go the electrical route and make sure you get all wiring as dry as possible. I dropped a cell phone in the water, after a week of drying out it works fine. Use a hair dryer to speed up drying time.
