Guys, How much of an upgrade are the VF3's? I've heard from some of my buds that they do more than a pipe?? Right now I'm running the Boyesen Pro Series Reeds....When i get up in my rpms, my bike acts funny and sorta sputters out but keeps running....I'm gonna try to look for em on ebay for cheap or may even buy them from Wildcard...I thought this might be a good upgrade from Boyesens....Give me some input on this and i can getcha rep!
