FIX IT!!!!
strip down the frame.
remove all paint about 2 inches on both sides of the weld.
take it to an aluminum welder with a TIG welder.
the way i would do it is:
replace the tube or
get the measurement recorded.
cut straight thru the crack so a good penetration weld can happen
slip a short piece of aluminum inside the tube from the bb hole to create a liner.
drill some holes before and after the crack-in these holes the liner can be attached by welding
this also re-inforces the area
weld up the crack and smooth it down.
should be one hour of a welders time.
I am sure frank the welder will be around soon-ask him!
