I have a 1996 Yamaha Banshee. Everyone says they are speed demons and have a ton of hp.. With mine, that's not the case... It has dual fmf powercore 2 mufflers and dual fmf fatty gold series headers, and a k&n air filter. It hits about 75mph and from what I hear online, 75mph is horrible.. I also have a hard time doing wheelies and i'm pretty built.. It's not peppy enough at all and when i race, i'm always way behind because it has horrible acceleration at the start.. I need help with mods. What are some mods I can do to my banshee that will make a big improvement that doesn't cost too much. I'm not interested in boreing it out, that takes the reliability out of the motor. I want it to go at least 85ish and have much more hp.. Also, how much hp gain do pipes get when they are jetted?
