Should have grounded closer to the weld, (on the kickstand) so the current didnt have to run through the frame. (CDI's and such).
Here is mine. Im NOT a row of dimes tig welder, I tend to just run a bead... Has MANY miles on it now, so its dirty, scratched etc.
weld was never touched with anything more than a wire brush, (and now some rocks, sand, brush).. the 2 lumps are due to kicking the breaker on the welder. had to crank her up to more than the wall liked
