If i were to put a 20-21mm carb on my bike, i would have to upjet the carb due to the larger amount of air coming through right? more air + more fuel = more power. I'm putting on a 70cc cast iron kit, 70cc high comp head, and ninja g3 exhaust. I would have to upjet my current carb, but with the new exhaust and more air being pumped out, shouldn't i pump up the air and fuel being pumped in? btw i was thinking of starting in the 90's nad working my way down till im not rich anymore.
