Difference in Carbs?

[2004LEBanshee]

I am confused as to what carb uses more gas. I have a friend with a rappy and it has like 28mm carbs and around 180 jets ( I think). Mine are 26mm but use 330. If we all use the same style main jet am I useing more gas? If so what is the purpose of a bigger carb, can't you just get bigger jets?

Bigger carbs do give you more gas yes. But its the higher volume of air that also goes into your motor with that extra gas which results to a bigger combustion or explosion in your cylinders, therefore more power.

I think you are runnig a Mikuni carb and your friend is using a Keihin one... Main jet numbers are in a different scale....

Let me rephrase this. I have a banshee with stock carbs he has a raptor with stock carbs. The raptor has bigger carbs then the banshee but my bansshee runs way bigger main jets then the raptor. They are both minuki carbs. I believe a 200 in one is the same as a 200 in the other. So why have a bigger mm carb when you could just run bigger jets?

bigger carbs = more air

 

bigger jets = more fuel

this is a good question.

I read that a 2 cycle needs more fuel to air ratio than a 4 cycle engine does.

I know it's not what you are looking for in a answer. But i though i would add this.
