YOu need 2 hammers & a friend. A 3 pounder behind the stem & a 1 pounder to spank it with. If thats enough to move it, & I suspect it would be, if not, a 4 pounder behind & maybe a 2 pounder in front,, thats the thing with bendin stuff,, sometimes ya need a bigger hammah,,
anyway,, put the heavy hammer up high on the back side, looks like about where the spring hooks on is where it starts, with the bike leaned away & the big hammer behind the stem, hit it below where the big hammer is. Dont try to get it all in one whack,,just spank it a couple o quick taps & look at it & SEE iF ITS MOVING, WHERE ITS MOVING & HOW MUCH. Ooop[s Caplox, sorry,.Anyway, the distance between the big hammer position in back & where the smaller hammer lands in front gives you a "fulcrum" but, if you step too far, youll need a heavier hammer in the back, Youll feel it when you get the right distance, youll feel the big hammer "buck" when you hit it with the one pounder. Walk your way down, its tapered, so, the hammer smacks will get lighter. I doubt youll need to mess with the angle of the foot if you get the stem right. Id really rather not see ya smack that part..

Thanks again for the help!  I used my 8 pound hammer as a backup and my 2 lb hammer to bend it back straight.  Also found a hard rubber puck and attached it to the pad with a machine screw.  The bike stands up much straighter now and I am no longer worried it might fall over.  

Now I am trying to build a center stand for it.
