Most of the modifications in this thread are old-hat and well-proven on the airhead frames. Unfortunately they all conspire to deliver a lot of stress to the main top tube which will eventually get overstressed and bend or crack. That said, I've seen at least twenty g/s & GSs with these mods and only one of them had a broken top tube.
It does make the rubber cow less rubbery.
Not one of you bastards welded a bottle opener to the frame....WTF?!
