Pete,
Once again, thanks for the feedback. From what I've seen Kelly's frame has some rather shallow relief machined into the top and bottom of his frame. Nothing of any significance and hardly noticeable once the gussets, fuel & air tank are installed and the whole thing painted. Once detailed, I doubt many could tell the difference. Again, don't get me wrong Kelly's a good guy and filled a need but I'll take the brass any day over aluminum.
Jay
