okay quick question. does anyone know how much modification would be needed to put an sr250 front end on a first year xs400? Im going to go ahead and assume that it won't just swap outright, but I like the look of the complete sr fork assembly better than the xs, so would like to figure out if a swap is even possible thanks! (oh ps been lurking for a bit and doing lots of research and snooping. will put some pics up of my brat/bobber/tracker/jobber/dealie project when I have some good ones)
