That is one fancy bike there. looks really nice. You need to figure out what system the water is affecting - fuel or electrical.

The fuel problems could be water getting in through the air cleaner or small leaks in/around the carb, if you are really diving into deep water.

The more obvious problem is electrical. You have water grounding out the components somwhere. Start with checking the plug wire for cracks and also how well the boot fits the plug to seal it. The check your coil and other components for open wiring. You should be able to drive through water without problems.

First thing to do is determine if you are losing spark. See if you can get it to die by letting it idle and spraying water on components (spark plug, coil, cdi box, stator to wiring harness connector, etc.)

Believe it or not, water is an insulator (made of hydrogen and oxygen - neither conducts electricity). Sometimes water gets into a connector and causes a poor connection and the spark goes away. You might need to tighten the connector pins and use Petroleum jelly or die-electric grease to seal out the water.

By the way - although water is an insulator, mix a little salt or other compound with it and it will conduct very well. Pond water is mixed with sodium, potassium, phosphate and virtually hundreds of other minerals that will conduct electricity.
