I was researching, and I saw that some stroker cranks will make a stock bore z400 a 450, is that true?? Also what causes that if it is true?

Yes i do belive its true.. It makes it true because engine cc is the measument of open space between your head and the top of your piston when the psiton is as far as it goes down(BDC). A stroker kit make the stroke longer which means that there is more open space in the cylinder between the head and top of the piston.

Also, I know that ur looking to stroke it but im just wondering what your gonna do with it because... (Stroking) Longer stroke smaller piston means higher quicker reving engine... (Over bore) Bigger Pisotn shorter stroke means more flat out top end power, Im just not exactly how darastic of a diffrience it would make

Hopefully tihs helps,
