There plenty of people around here that ride in a lot of water with no problems. I think if you are running in deep water for extended periods of time, as in minutes not seconds. You may consider it. Since your mainly a trail rider I would not sweat it. Just leave it as it is. I put some RTV on the pull handle to seal up the top better, but that is it.
As far as voiding the warranty, Dunno. Depends on what you are taking it in for. If you broke a CV, I don't see how the leaksheild would have anything to do withit. But if you got water into the motor from something other than the recoil, I doubt it would be covered. I would consult your dealer before installing one. There some dealerships that sell them.
