I know this isn't the best site to ask a question on a Quest, but here it goes anyway... I'm in the middle of getting this machine and was wondering how they are when it comes to deep water (up to the headlights). Does the belt stay dry? Does the water stay out of the air box? Also, how are the tires for mud and snow? I like to ride in the winter time, so having a good tire for snow is a plus. Also, are there any cheap mods to boost the power on these things, or are they pretty well maxed out as the are? Thanks for the info.
