Bike Carbs on pinto and cvh

[Rik178m]

Got 2 engines which will eventually go in my roadster a 1600 CVH and a 205 pinto.

Just got a set of ZX9R carbs as they were fairly cheap. Are they suitable for either engine?

I notice on another forum alot of people are using 600cc carbs. Are these better? I would have thought bigger the cc the better for car engines?

Whats should I be looking for ?
