u can get a 24mm dellorto too
I am really curious as too how much a difference just that carb makes on a sick setup, it would be an interesting test to run an 80metra with simonini on both carbs and the same intake and see what the difference really is, bigger is not always better.
but they do rip, however so do large delloto's, for example, my polini setup with dellorto 19mm and techno boss, is in the same speed bracket as most peoples 80metras, gillas, and 8p, simonini, 24 flatslide setups. It has been my experience that while there are faster bigger setups than mine, there are just as many if not more slower bigger setups.
My point is the larger carb does not guarantee speed, and I think the dellorto is more versatile since it can be used on smaller setups as well. honestly a simonini pipe will make more of a difference.
its all very debatable.
