My brute 750 is still sputting when i ride it for a long time and than go into some fairly deep mud and water. Nothing that i would think should cause the brute to sputter. It is not even that high of water. over the tires of course but not even close to the front rack. I have already took out and removed "Carb vent" (the little clear plastic tube on the front of airbox and rerouted to under the handle bars )
have not tried putting dyelectric grease on coils yet but i just don't know why it will sputter out like this. I am going to be getting a dyna fs soon will this stop the sputtering. It doesn't go completely dead but it just seems like it has to catch up after you hold the gas for a little while. I have also heard that the steam could cause this but I find this hard to beleive ANy help would be great!
This is an 05 brute

 

Any help would be great I hope I'm not the only one who has had this prob.

 

I had the same problem and it was "Steam".
You just need to make some Mods to prevent this "steam" to enter the poor design of the air-induct system on the BF's.
