welding xr650r subframe and frame

[chicago650r]

Hi. Sorry I mistakenly posted this originally as a reply instead as a new thread, first time user. Anyhow, I want to stiffen my subframe to accom-

omdate panniers and less importantly a passenger. I need to know what type

of aluminum(by number) the frames are made of and what type of tig welding rod to use.

I have 4043 and 5356 filler rods in my welding arsenal. Thank You.MM

They talk about welding the 650r frame in this thread.
