At my first race a few weeks ago, my mouth got very dry during the first moto, and then again in the second moto. it sucked. felt like i was going to die of thirst. i was breathing through my mouth in both motos but i don't know if that has anything to do with it, because i've seen pros doing it in pictures, and i think it's kind of hard not to breath through my mouth when i'm riding. how do you all keep your mouths from getting so dry when you ride? thanks.
