Hi,

I'm building an NS400 project bike, an am planning to fit NSR MC18 carbs. But before i do, can anyone tell me if MC21 carbs are the same type? Are they larger bore?

I've seen a few threads where people have recommended MC21 carbs asthe best option, can anyone give specific details (size etc) as to why the MC21 carbs would be a better option than the MC18?

Any advice appreciated!

thanks, Mat.
