It seems failures on SMT subframes are all too common - there's a ton of repair/bracing jobs to be seen online.
Now...I normally never fabricate or repair motorcycle parts for anyone but myself; I don't want to put anyone at risk. Wouldn't do it for paying clients either - compared to many, Australia isn't a very litigious society but again, why risk legal hassle. But this guy is a very good friend and he understands that the repair comes with no guarantees and no comebacks. (He's priced the new replacement part

Now...the part is probably 6061 (I know...cue the guesswork already!). I would normally clean, create a jig and weld with 5356. I am aware that none of this is ideal, that annealing will be a concern and that ideally, this part really needs professional welding and re-tempering.
Would love to hear any thoughts and advice you people might have. I seem to remember that Dunkster is the man for this kind of thing, but there are lots of other smart people on here. Cheers!
EDIT: Is it just me who finds it strange that the factory welds are only along the sides of the joint?
