Need help making a decision on 212cc or 420cc

[Drewborice]

I’m thinking about buying a billt rod flywheel spring maybe cam for my 196cc clone either that or a stick 420cc to put on my chopper project or maybe my yard kart idk yet I need help which option would you pick and if I go with upgradeing the clone about how many Rpm’s whill it be able to handle like that and how can I make it get that high I heard I would need stiffer springs

Wow that's kinda wall of text... How about some punctuation.... So it makes better sense....
