Ok here goes. I built this banshee a couple of years ago, and have never been able to nail the jetting. Mods are 4mill, bored .02 over, dune play port by FAST, + 4 timing, VItos hemi head two @150 psi a hole, boyeson rad valve reed cage, 32mm Mikuni tm flastslides, KNN pods, and toomey t5's. Current jetting is 300 main, stock pilot needle at lowest clip and airscrew 2.0 turns out.
The machine is breaking up in the mid...but will wind out given enough time.
Thanks for the help guys...
