Yamaha YFZ350 Banshee (1987-Present)
So im new to bansheeeees!!Its also my first build but my question is about jetting! i just got Toomeys T5s and K&N dual filters and as far as airbox goes that is still to be determined by what is best? getting cylinders bored out to 64.50 and everything else is stock!So what would be my best...
