hey guys i just got my 06 foreman 500 es about a week ago, i've been reading through the post and love all the info on the site. i have a few questions to ask and sorry if they have been answered before but i recently moved into my new house and don't have dsl all i can get is dialup and don't have the patience to do a search. first i noticed a small hose coming from my fan, what is this? also does anyone know the factory horsepower, and how much is gained from the common mods, like exaust, jets and so on. i'm sure i'll have more to come and thanks in advance for your replys.
