I just purchased a 1998 kx 250, and it has v-force 3 reeds on it, what are these suppose to have improved, unfortunately i have never experienced the bike stock.
From what I understand they will provide a better fuel/air mixture thereby increasing performance across the entire rpm range. I've got friends that swear by them but I havent taken the plunge yet.
I don't regret my buy because I ride a 125 and already have an exhaust system so this was the next best thing on the list, besides porting but that makes the bike less reliable, these are meant to make it more reliable.
