98 220 all stock.I ride mainly woods with some open sand pits and an occasional mx track.What I'd like to know before forking out the bucks.Does a new exhaust really "wake up the kdx" as I've heard?I just don't want to fork out alot of cash for mods,ie.fork springs,reed valves and exhaust if it doesn't really make a significant improvement.Maybe I should just sell it and get a kx 250?sorry for the long post.Just undecided.
