i am new to this site and not very proficant with a typwriter that being said i will give it a try. i have bought a xs 400 my son wanted the seat lowerd so i chopped the tubing up by the back bone and at the shock mounts wanting to put acurve in it but i dont have a tube bender so trying to improvize i noticed that 5/8 rebar fits in the tube was wandering if anybody knew if the rebar would be sufficiant enough to put in the tube hole and run back to new shock mounts
