I got something for the turbo yfz. Lol. The 450 came out in 04 and has always been a fourstroke. The banshe is a yfz 350. With ur mods u should take out the yfZ. He might get u out of the hole but youll pass him. I have both yfz 450 and banshee on alcohol but the banshee is way more modified and no 450 will be close to it
