So that repair lasted about 35K km (& just the one or 2 jumps with full luggage

)

Found this yesterday. So off with the subframe, out with the TIG. Added an extra gusset.

Still a bit of a learner on the TIG so the welds are slightly ugly. Will see how it goes. Just used ER70S2 rod. Word on the street is that if the weld area stays good & red for 5-10sec after welding post heat treatment should not be required.

Cheers
Clint
