To be honest this is kind of a new issue for me we stop boats for boats and four wheelers or four wheelers but if you don't have all your carburetor vents up towards the handlebar as high as you can get them in the chassis you're going to get water in the vents. She won't tend to suck the water down but she also won't allow the carburetor to vent properly

Do you have a watertight plug cap? Is water getting in your fuel tank?(fuel floats on water) Have you checked for any leaks around the carb, rubber inlet boot etc? You could have a small air leak (intake) would run fine until you dunk it in a puddle.

Also, does it bog/misfire at full throttle if your just in deep mud, no water?

No no, not fuel leaks, air leaks... You could have a tiny air leak that may not be affecting the way your machine runs (yet) but, if air can pass through so will water. Water would cause a misfire.

I did two things I'm not sure which one did it but I replaced the coil and there was a spot on bottom of carb that looked like it needed a vent line on the bottom right it wasn't the over flow it was another so I ran a vent line and it seemed to work
