I've seen a few pictures and a youtube video of a 1990 GPX 600 streetfighter that had a R6 tail, but I can't find any info on how to mod it other than the angle of the tail needs to be raised. Just wondering if anybody has done this or something like it? any advice before I try it myself is appreciated. Mainly if I should just extend the frame to get the proper angle, or just buy a R6 subframe? And would I still be able to use a stock R6 seat or have to make a custom one?
