since you guys mentioned the 450 i was wondering who would win in a cross country race against my cr500 banshee and a yfz450. my mods are" cr500 engine, ftz drag pipe, ported, wheels and tires and some stickers. oh yea i have handlebars too. the yfz is all stock. who will win and how much money should i put on this race? i think i can take him but he says his 450 has a jet engine in it. im not sure but i think he said he has retractable wings too. so he might be able to fly. i dont wanna let this 4 stroke chump beat me so i dont know what to do. any suggestions??
