Motorcycle Repair: yamaha banshee, good luck man, high grass

Question
I was riding my banshee one day through deep water and high grass two days in a row.  The second day in the middle of a donut it started bogging.  I put new plugs in but it didn't change.  It runs fine straight through 4 gears.  fifth gear and hard turns it bogs real bad.  I took the carbs, removed the bowls and cleaned with carb cleaner.  I sprayed the jets out and reinstalled them.  No change.  I have no idea what to do.  I can't afford a 90 dollar an hour bill at yamaha.  Hopefully you have an idea and even better would be a simple, cheap fix.  Thankyou for you time and input.

Answer
Hey Brain,

Why are you rideing a banshee in water, HaH joking.
I would have to think you have water or some type of mostier in the sater the point's. Take off the side cover and use  brafe parts cleaner and make sure u get it all clean.. Banshee's are a pain i have a drag Banshee that has Ran in reverse, lost 1-3 gear for no reason and one day would not start..They have there day's but good luck man.
