Hey Trav, Been ceeping the page for quite some time! Lots of info on here I needed. I wanna hardtail my 400 but I was wondering what your opinion would be seeing is ive never done it. I wanna switch it to a single back bone, do you think it would be better to buy the 1 1/8" and sleeve the lower rails, or just buy the 1" and butt weld it?
