the frame hinge unbolts for the SOHC supersport seat so just use that, if you absolutley need to weld then weld it insetad of bolt it to the frame. If you try to weld an assembled seat you will catch it on fire (ask me how I know). Supersport seats open opposite of 69-76 K seats so you really can't reuse the hinges anyway (although they both fit the frame - the shape of the pans are different. Also I don't know what you are going to do about a lock (not that you need it, several of my bikes have not had seat locks for years), the lock bosses are welded to the frame.quote:Originally posted by 75SevenFityFo
Geeto, Yes, no rear fender. I hate the look of the tail like bracket. I was planning or making a custom one to hold the plate/light. Easiest way I figured. I am looking to have a tail of some sort and still have room for two. the 75'-78' supersport seat sounds like the most logical. I definatly like to function of the hinged seat. If not drilling, i could cut and weld the old hinges onto the new pan? Now to find a supersport seat ... thanks very much for the all the info.
