Sounds like water in the carb bowl. Probably water in the tank/s also. I would clean and blow out the carb, fuel cell and another fuel filter and see how it runs.

While you have the carb. bowl off spray carb. & choke cleaner through the main jet making sure it's fully open.

Check your safety under the seat. Wiggle the black box and make sure it is tight.
