How do I know if I need bigger carb?

[Carlos motors]

I have just finished rebuilding my engine. I have ported it a bit, like 1-2mm on eaxh side of exhaust and intake. Im not 100% sure but I think my intake is 24 at top 26 at bottom and exhaust is around 26mm. My exhaust is somewhat of expansion chamber, anyway better than stock. I was wondering do I need a bigger carb. I have some money left behind so should I condider buying some mikuni or oko carb and is it worth the money?

Unless your going reed i would stick with that. The only thing i would get with a mild ported engine is a delorto clone, and a pack of jets. A oko or mikuni is overkill if you dont have reeds, if you get a g2 reed then go for it.
