Has anyone ran a 15 tooth sprocket before? I am curious on how the banshee will run. My banshee has a 13t, cool head with 21cc domes, lighten flywheel, 4 degrees advance, fmf gold series pipes fatties, no air box, the filter are directly on the carbs, it has been rejetted, pretty much stock. I drag race and like dunning just as much. I treid a 12t before and it was just way too much shifting in the dunes.
