Hi, can antone help me out.
My dad has a banshee with FMF Gold Series pipes + Silencers, reeds, Shaved head, and jetting. It was all set up by Yamaha themselves, who really knew what they were doing. they dialed it in perfectly, and when they dyno'd it, it was around 52-54 Horsepower.

Does anyone know what just a port job done to it will make?
Were thinking of sending the cylinders out to be ported, probably an mx port.
Thanks!

You shouldn't have any problems getting 60+ horsepower out of it, and still have a somewhat smooth powerband, if there is such a thing on a banshee!
