I was wondering if anyone could tell me how well a stock 250x pulls through mud and water? as well as how well it keeps water out of the air box? I currently have a 230f and it doesn't like water at all, always bogs and dies. thinking about a switch to a 250x I do alot of mud/water/single track where torque is most important so i was also wondering what year 250x has the best torque stock? i think i read the 2009's changed the head and has less. so are the 2008's and down all the same?
