street 500 and 750 bore kits

curious what people think about boring out the motors. how big can you bore out the 500 and 750? with the cheaper price of the Street - this could be something to consider to get some more power. since the 500 and 750 are pretty much identical apart from the displacement. maybe you could bore a 500 to a 750 and a 750 to something larger possibly?

I'm sure Harley designed some displacement growth into this engine. It won't remain a 750 forever.
