they really dont list our bikes but i did call them and they offer a kit that make the 475cc motors we have to 535cc. you send them you cylinder and stuff and they send it back to you already done. i think he quoted me around 350-400 bucks. i also asked about any additional cooling add on would be needed. he told me none. just thought i'd share this with you guys. dont know if i'm ready for that yet. i know the more you modifiy things the more they break
