I have a stock bike with only a dg slip on . I ride some slow trails but a lot of farm roads and fields . I would like a little more bottom end without losing top end . I also love the fact that I can stand the bike up in 3 rd gear for a wheelie and don't wanna lose that either but just want more quickness . So which sprocket set up should I go with , also was thinking about which air filter should I change 2
