When folks mention the blocking of the crossover, I can't help but get a visual of using a grinder w/cut-off wheel and creating a slot in the crossover from the underneath side. (Pipes still on bike)
Slot would be 'across' the pipe and approx. 1/2 the way through. Insert a metal disc into the slot and,,,,,,,,,,,,,,,,,,,,,,,,,,,,

We used to be able to weld on vehicles safely if certain electrical items were disconnected first,,,
Does anybody know for sure what has to be disconnected on a Wing before arc welding can occur??? Is it even possible? What about 'old school' gas welding/brazing?
(I'm no welder, so I can only 'guess' at what might or might not be possible)
Or,,,,, if the slot/disc had a tight fit,,,, would a band clamp work???
