i thinking about purchasing a 250f in about a month or so after coming off a 250 two smoker. i rode a kawi 250f 2 years ago in B class and felt better on it than the two stroke. Im pretty set on getting a honda. i have been riding since i was 4, and racing since i was 10. This year im moving to A class and want a bike that will treat me good. i was wondering what mods people have made to their crfs that had made the most noticeable change for the money spent. And what can i do to avoid some early problems that the crfs may have right from the factory. Also i dont know if i should grab an 07 now and try and get a cheap deal, or wait for an 08? any feedback would be alot of help thanks!
