hello all. Im new to the site. i dont have my 'busa yet, but am looking for 1 now. but here is my question. i like the 2k (unrestricted) busa's the most.. but not the colors of their fairings.. but im TOTALLy digging the 2k4 black/purple fairings. are these fairings/gas tank interchangable or will modification b needed? just checking to see if i can save alot of $ and just put new fairings on or just save a few $ and get a 2k4 model.
